Description
- The present invention refers to a crane for lifting loads, which can can be mounted on a relative vehicle and in particular mounted on a truck.
- In the field of truck-mounted lifting cranes, vehicle stabilizer means are known consisting of a first and a second telescopic stabilizer arms which extend outwards in front of the driver's cab of the truck in order to stabilize the front part of the truck during lifting operations. These first and second front stabilizer arms of the lorry extend outwards on opposite sides of a support base supporting the lifting boom of the crane and consist of arms which extend, retract and rotate, thanks to actuating means, with respect to the support base and which, in their rest position, are longitudinally aligned with the vehicle driver's cab, in particular, alongside the support base of the lifting boom.
- This stabilizing system with rotating telescopic arms is used in combination with a load lifting boom which also extends in its rest position lengthways to the vehicle to the rear of the driver's cab. This type of truck or truck-mounted crane is designed for lifting only and the body or flat bed to the rear of the driver's cab can only be used for stowing the lifting boom in its rest position and for no other purposes. Furthermore, this type of crane uses an excessive number of actuators for operating the stabilizing elements.
- Similar stabilizing means are used to stabilize the rear part of the truck.
- Another known solution involves the use of a lifting boom which in its folded rest position is located crossways with respect to the cab so that other loads can be carried to the rear of the cab on the truck bodywork.
- In this case, in order to obtain a conveniently long crane outreach, rotary telescopic arms to the front of the cab are not used as stabilizers because in this case they are provided with stabilizer jacks which are fixed to the front of the truck driver's cab directly to the truck support structure in such a way that the structure underneath the driver's cab requires structural stiffening so that the stabilizer jacks can be conveniently anchored to the load bearing structure of the truck.
- It is provided a crane for lifting loads mounted on a relative vehicle with a longitudinal axis and in particular a truck comprising a support base for the crane mounted on the vehicle from which vehicle stabilizing means extend where said means comprise an extending arm carrying support means resting on the ground, characterised in that the extending stabilizer arm is fixed to the support base and extends outwards from the support base in a direction at an angle to the longitudinal direction.
- In this way it is provided a convenient stabilization of the vehicle on which the crane is mounted without incurring the excessive manufacturing costs characteristic of the known solutions where an excessive number of actuators are required and modifications have to be made to the load bearing structure of the vehicle.
- These features and further ones of the crane according to the present invention.
- Further features and advantages of the invention will become apparent from the description of an embodiment which follows with reference to the annexed drawings, given purely by way of a nonlimiting example, in which:

Figure 8B shows a perspective view seen from a slightly different angle compared withFigure 8A of the support base and the stabilizer extensions of a preferred embodiment of a lifting crane according to the present invention; -
Figure 9 shows a rear view with the stabilizer arms in their extended position and shows the support base only and the stabilizer arms of a preferred embodiment of a crane according to the present invention. - The figures show a
preferred embodiment 10 of a load lifting crane, in particular a telescopic boom crane, which is mounted on avehicle 11 comprising a truck with, as shown in the figures, a driver'scab 11a and aflat bed 11b, partly illustrated in the enclosed figures. - The
present crane 10 is mounted close to the rear of the driver'scab 11a and could also be mounted on the truck on the rear end of theflat bed 11b. - The
present crane 10 comprises, as described more fully below, alifting boom 13 of a folding type which in its rest position extends crossways to the longitudinal axis "L" of the truck. - In particular, the
lifting crane 13 has amain element 13a on which is jointed or folded aboom element 13b comprising a plurality of telescopic elements 13'b and 13c which can be extended and retracted by the action of the correspondinghydraulic cylinders 13d. - In particular, as shown in the figures, the
boom element 13b of the crane extends, in its rest position, lengthways alongside themain element 13a connected to the slewing rack of the crane. - The
crane 10 comprises asupport base 12, connected to thelongitudinal support members vehicle 11, to which the lifting boom is connected by means of acorresponding slewing rack 15 which rotates around a vertical axis and from which the corresponding vehicle stabilizing means are extended when the crane is working. - These vehicle stabilizing means comprise a first extending arm, marked with the
reference number 14, which carries the corresponding ground supports which in turn comprise avertical jack cylinder 16 with afoot pad 16a. - In particular the
support base 12 extends in a substantially linear direction along the longitudinal axis "L" of the vehicle and has afront face 12a, aback face 12b and opposing side orlateral faces - Advantageously, the extending
stabilizer arm 14 can be connected, in a fixed manner, to thesupport base 12 and extends outwards from thesupport base 12 at an angle "A" with respect to the longitudinal direction "L" of the vehicle. - In this manner the invention provides an
arm 14 which is solidly anchored to thesupport base 12 and is able to stabilise the vehicle in the area in front of the driver'scab 11a as illustrated inFigure 7A . - However, it should be understood that wherever the present crane is mounted in the rear position on the truck, that is, on the rear end of the
flat bed 11b, thepresent stabilising means 14 must be able to rest on the ground lengthways beyond the rear end of the truck thereby making the truck more stable in this situation. - In practice, the stabilising
arm 14 fixed to thesupport base 12, when fully extended, extends with itsend 14' fitted with the ground support means alongside the respective side of the driver'scab 11a of thevehicle 11. - The angle of orientation with respect to the longitudinal axis "L" is marked in the figure with the reference letter "A" and is an angle of less than 90°, as shown in the
Figures 7A and7B . - Advantageously, as shown in the figures, the
stabilizer arm 14 extends from thesupport base 12, starting from an intermediate zone of therespective side face 12c of the support base, in particular from a zone of theside face 12c of thesupport base 12, which is situated in the front part of theside face 12c. - Advantageously, the
stabilizer arm 14 is part of thesupport base 12 structure and in particular of the intermediate zone of thesupport base 12. - In particular, the
stabilizer arm 14 defines part of the structure of thesupport base 12 at or close to the zone of the crown wheel 15' of the slewing rack of thelifting crane 13. - As shown in the figures, the
stabilizer arm 14 has atail end 14', which extends outwards from thesupport base 12 at theside 12d which is opposite to theside 12c from which thearm 14 also extends. In particular, as shown in the figures, thetail end 14' of thestabilizer arm 14 extends from an intermediate and rear zone of theside face 12d of thesupport base 12. - As shown in the figures, the
stabilizer arm 14 extends crossways and diagonally through thesupport base 12. - In this way the invention provides a
stabilizer arm 14 which has a considerable length when fully extended and thereby provides effective vehicle stabilizing in the area in front of the vehicle. - Advantageously, the
stabilizer arm 14 has a plurality of extension sections and, in particular, has anelement 14a which is fixed to thesupport base 12 thus defining part of this structure, and one or more extension elements, and in particular a first and asecond extension elements - In practice, as the figures show, the
fixed extension 14a receives coaxially inside its interior the firstmobile extension 14b and the secondmobile extension 14c which in turn is coaxially contained inside the secondmobile extension 14b and which carries on itsfree end 14" theground jack 16. - In particular, as shown in the figures, each of the
elements stabilizer arm 14 has a quadrangular cross-section and is longitudinally linear or straight. - Advantageously, as the figures show, the
element 14a of thestabilizer arm 14, which is fixed to thesupport base 12, has a head end 14'a from which one or more of the extension sections of thearm 14 extend and where the head end 14'a of thefixed element 14a extends out of thesupport base 12 beyond therespective face 12c of the support base. As the figures show, the fixed element of thestabilizer arm 14 has a head end 14'a which extends from arespective side face 12c of the support base and in particular from the front part of theside face 12c. - Advantageously and as shown in the figures, the
fixed element 14a of the stabilizer means 14 has atail end 14' which extends from theside 12d of thebase 12 which is opposite to theside 12c from which thestabilizer arm 14 extends. - The
fixed element 14a of thestabilizer arm 14 has, advantageously, a height which is substantially the same as the height of thesupport base 12. - In particular, the
fixed element 14a of the stabilizer means 14 defines part of the structure of thesupport base 12 and extends diagonally to this and, in particular, diagonally to the longitudinal axis "L". - Furthermore and as illustrated in
Figures 7A and7B , thefixed element 14a of the stabilizer means 14 extends from the fixing zone 15' for the rack of thelifting boom 13 but remains under this and in particular remains under therear zone 15" of this one. - Advantageously and as illustrated, the
fixed element 14a has atail end 14' which extends out of the support base at the intermediate zone of theside face 12d of the support base and in particular at the zone to the rear of theside face 12d of thesupport base 12. - As illustrated, the
fixed element 14a of thestabilizer arm 14 has atail section 14' which is positioned in a longitudinal direction to the rear of the tail end 14'a of the samefixed element 14. - Advantageously, and as illustrated in particular in
Figures 1B ,2 and 3 , thecrane 12 has alifting boom 13 which in its rest position has an end 13', in particular defined by the corresponding end of theboom element 13b which extends below and alongside thesupport base 12. - In particular, the end 13' of the support boom in its folded state extends alongside the
side face 12c of thesupport base 12. - In particular and as shown in the figures, the
lifting boom 13 in its rest position has a lower end 13' which is located close to the extension zone of thestabilizer arm 14. - In practice and as illustrated, the
stabilizer arm 14 has afixed element 14a which extends below thelifting boom 13 in the crossways rest position, in particular below themain part 13a of the lifting boom, while theboom part 13b is vertically positioned to the side of the part 14'a of the stabilizer fixedelement 14a. - In particular and as illustrated, the
stabilizer arm 14 has an end 14'a from which themobile elements main fixing element 13b of thelifting boom 13 in the crossways rest position. - In particular, the end 14'a of the
stabilizer arm 14 is, as can be seen in the figures, vertically aligned or substantially aligned to this end 13'a of theelement 13b of thecrane 13 in its folded rest position. - Furthermore and as illustrated, the
rear part 13" of thelifting boom 13 in its rest position is also located above thetail end 14' of the fixed element of thestabilizer arm 14. In particular, thetail end 14' of the fixed element is vertically aligned or substantially aligned to the rear end of the telescopic or liftingpart 13b of the lifting boom. As illustrated, thesupport base 12 has on itsside face 12c a recessed portion defined by a surface inclined at an angle to the vertical where this recess defines a seat or zone for the end 13' of thelifting boom 13 in its rest position. This recess is marked with thereference number 17 in the enclosed figures and the inclined surface, delimited by the recess, is marked with thereference number 17a. This arrangement makes it possible to obtain a lifting boom with a particularly long outreach. - As illustrated, the
section 14a of the fixed element of thestabilizer arm 14 projects from thesupport base 12 immediately to the side of therecess 17 and extends along the inside of the base 12 to the rear of theinclined surface 17a, in other words, in a position immediately to the rear of theseat 17 for housing the corresponding end 13' of the lifting boom in its rest condition. - As illustrated, to the rear of the
recess 17, theside face 12c of thebase 12 has a rear portion 12'c which is longitudinally aligned to theportion 12"c which is in front of therecess 17. - As illustrated, from the
side 12d, opposite toside 12c, which is the extension of the diagonal stabilizingarm 14, there extends a second stabilizing arm marked with thereference number 18 advantageously in the form of an extending arm comprising a plurality of elements and, in particular, a base ormain element 18a which is connected rotationally to thesupport base 12 by means of avertical pin 20 so as to permit the rotating stabilizer arm to rotate from a stabilizing position angled with respect to the longitudinal axis "L" extending forwards alongside the driver'scab 11a and a retracted, rest position where thearm 18a is located to the side of the base 12 positioned in a longitudinal direction as indicated in particular inFigures 3 to 5 . - In this retracted position, the rotating
stabilizer arm 18, as shown inFigure 3 , has its rear end 18'a of the main element on the extension and alongside thetail portion 14' of the fixedelement 14a of thefirst stabilizer arm 14. - In practice and as illustrated, the rotating arm pivots on a front and side end of the
support base 12 and has second and third extendingsections vertical jack cylinder 22 fitted withfoot pad 24 resting on the ground. - The
rotating arm 18 in its extended working position extends to the side of the driver'scab 11a of the vehicle side opposite to the side on which the fixedarm 14 extends and is oriented at an angle B with respect to the longitudinal axis of the vehicle. - The extended working position is reached by rotating the
arm 18 forwards, starting from a position where the extension sections are retracted as shown infigures 2 to 5 and where the arm is located substantially lengthways alongside the support base. - As shown in the figures, the angle B between the
stabilizer arm 18 in its work position and in its longitudinal position is an angle of less than 90°. It is clear in particular fromFigure 7A that it is provided a lifting crane with a considerable outreach or extension of the lifting boom and at the same time provides optimum vehicle stability also in the area to the front of the vehicle. - As it is clearly shown, in particular in
Figure 6 and inFigure 5 , the end 18'a of the main extension element of the second stabilizingarm 18 is located, in its rest position, below the rear portion or end 13" of thelifting boom 13 and in particular below theend 13" of thetelescopic element 13c of thelifting boom 13. - As the figures show, the rotating
stabilizer arm 18 comprises a plurality of extensions coaxially contained one inside the other. In particular, theextension 18c is contained inside theextension 18b which in turn is contained inside thejointed extension 18a; the extensions or elements of thestabilizer arm 18 have a matching quadrangular section and extend in a straight line. - It must be understood that the location of a diagonal fixed arm on one side of the support base and the location of a rotating stabilizer arm on the other side of the support base, irrespective of the side of the support base actually used, is possible according to the present and advantageous lifting crane.
- Obviously, in a layout where the support base is in a position to the rear of the crane truck, the rotating
extension 18 can be extended longitudinally beyond the rear edge of the crane truck thus advantageously providing stabilising in this area. - The
support base 12 has the form of a box section body comprising first andsecond profiles base element 12a of thediagonal stabilizer 12, extending longitudinally and parallel to each other but having different lengths. - The front profiles 121, 122 of the
box section body 12 have front projecting ends 121', 122' and extend until they reach the corresponding side wall of the fixedprofile 14a of thediagonal stabilizer 14. - The
support base 12 further comprises first and second rectangular section profiles 123, 124, which extend to the rear of thebase element 12a of thediagonal stabilizer 12 and which also extend longitudinally and parallel to each other on the extension of thefront profiles - The
rear profiles box section body 12 each have projecting front ends 123', 124' and also extend until they reach the corresponding side wall of the fixedprofile 14a of thediagonal stabilizer 14. - The base
box section body 12 has anupper plate 125 which is applied above the upper wall of theprofiles lower plate 126 which has acentral portion 126a which extends between the lower walls of theprofiles side portion 126b extending outside the same lower walls of theprofiles - The
side wall 12a of thebase 12 coincides with the corresponding side wall of theprofiles - The outer parts of the
box section body 12 comprise a frontvertical wall 12a, a rearvertical wall 12b andcounter-opposing side walls side wall 12a has arecess 17 for housing the corresponding end 13' of the lifting boom in its rest position and where theside wall 12d has a longitudinal profile or design which is recessed at the rear part of the same wall and where thetail end 14' of the diagonal stabilizer arm extends beyond therear part 12"d of thewall 12d and terminates in a position which is substantially aligned with thefront part 12'd as shown inFigure 3 . - In practice, the
front part 12'd of theside wall 12d is situated laterally to the outside of therear part 12"d of thesame wall 12 to which it is connected by acurved radius section 12e. - The
rear profiles - The
joint pin 20 of thesecond stabilizer arm 18 is supported by twohorizontal plates part 12d of thewall 121 at the front edge of thebase 12. - A section of quadrangular,
tubular profile 128 supports thehinge plate 127 in a position which is raised with respect to theupper surface 125 of thebase 12. - It is provided a support base structure which is strong and enables the optimum fitting of the components supported in compact overall dimensions. The present invention provides a crane structure which provides considerable stability for the vehicle mounting the crane. It enables optimum use to be made of the space available on the vehicle for loading other elements. It also enables a relatively long outreach for the lifting boom.
- The invention described is susceptible to industrial application and may be modified and adapted in several ways without thereby departing from the scope of the inventive concept. Moreover, all the details of the invention may be substituted by technically equivalent elements.
