Description
- The present invention refers to a lifting vehicle, comprising:
- a self-propelled chassis,
- a telescopic boom articulated to the self-propelled chassis and fitted with a connection for the mounting of equipment, and
- at least one cylinder for lifting/lowering disposed between the telescopic boom and the chassis.
- Lifting vehicles of this type can be equipped with different types of equipment, such as forks, shovels, aerial platforms, etc. During operation, the load applied on the equipment located at the end of the telescopic boom may vary within very wide ranges.
- One of the fundamental safety elements of a lifting vehicle is its stability to longitudinal overturning.
- Usually the vehicle is equipped with a load diagram that indicates the maximum load that can be applied at the end of the lifting boom depending on the position of the equipment.
-
EP-A-1312579 discloses a lifting vehicle according to the preamble ofclaim 1, wherein an electronic control system generates an electronic load diagram and displays on the electronic load diagram a cursor located at the working position of the boom. However, compliance with the load diagram is left to the operator. - Usually, vehicles with a telescopic lifting boom are equipped with a safety anti-overturning system which blocks or reduces the speed of movement of the lifting boom when the rear axle load falls below a predetermined reference threshold. In fact, the reduction of the load on the rear axle below a critical threshold indicates that the vehicle is close to a condition of overturning. An example of an anti-overturning system of this type is disclosed in
EP-A-1897847 . - One problem of the known solutions is that the anti-overturning safety system of the known type is not a sufficient safety guarantee in dynamic conditions. The anti-overturning system of vehicles of known type is essentially designed for safety against longitudinal overturning under static conditions. If the anti-overturning safety system blocks the boom during the lowering of the boom at high speed, the inertial force may cause overturning of the vehicle.
- The situation is made even more complex by the fact that the risk conditions vary considerably depending on the type of equipment that the vehicle uses.
- The present invention aims to provide a lifting vehicle with increased safety against longitudinal overturning under dynamic conditions.
- According to the present invention, this object is achieved by a vehicle having the characteristics forming the subject of the claims.
- The claims form an integral part of the teaching administered in relation to the invention.
- The present invention will now be described in detail with reference to the accompanying drawings, provided purely by way of a non-limiting example, wherein:
-
Figure 1 is a perspective view of a lifting vehicle with telescopic boom, -
Figure 2 is a simplified diagram of the control circuit of the vehicle boom ofFigure 1 , and -
Figures 3 and4 show two load diagrams of the lifting vehicle with different loads and indicating ranges with different maximum speeds of lowering the telescopic boom. - With reference to
Figure 1 ,numeral 10 designates a lifting vehicle comprising a self-propelledchassis 12 having afront axle 14 and arear axle 16. Thevehicle 10 comprises atelescopic boom 18 articulated in the rear section of thechassis 12 about atransverse axis 20. Thetelescopic boom 18 is equipped at one end with anattachment 22 for the connection of different types of equipment. - The
vehicle 10 comprises at least one cylinder for lifting/lowering 24 with ends articulated to thechassis 12 and theboom 18 aboutrespective axes 26, 28. Theboom 18 is also equipped with a cylinder (not shown) which controls the telescopic extension and retraction movements of the boom. - With reference to
Figure 2 , thevehicle 10 has ahydraulic control circuit 30 which includes a main pump 32 driven by thethermal engine 34 of the vehicle. Thehydraulic circuit 30 comprises ahydraulic distributor 36 that receives fluid under pressure from the pump 32 and controls thehydraulic cylinder 24 by means of ahydraulic supply line 38. Thedistributor 38 is connected to areservoir 40 via adischarge line 42. - The
hydraulic control circuit 30 comprises ablock valve 44 controlled electrically, disposed on thesupply line 38. When theblock valve 44 is activated it blocks the movements of theboom 18 that worsen the risk of overturning (lowering and extension). - The
hydraulic control circuit 30 further includes arelief valve 46 controlled electrically. Therelief valve 46 is adapted to limit the maximum speed of lowering of theboom 18. The lowering speed of theboom 18 is controlled by the operator through thedistributor 36. Therelief valve 46 limits the maximum flow rate of fluid on thecommand line 38 and consequently limits the maximum speed of lowering of theboom 18 as a function of the electric control signal which it receives. - Again with reference to
Figure 2 , thevehicle 10 includes acontrol system 48 which controls, among other things, theblock valve 44 and therelief valve 46. Thecontrol system 48 comprises anelectronic control unit 50 programmed to control therelief valve 46 in function of the position of theboom 18, of the load applied to it and the type of equipment applied to it. - The
control system 48 includes aload sensor 52 which provides an indication of the intensity of the applied load to theboom 18. Theload sensor 52 can be for example a load cell applied to the cylinder for lifting/lowering 24. Thecontrol system 48 comprisessensors boom 18 and the length L of extension of the telescopic portion of the boom 18 (boom extension). Thecontrol system 48 also comprises arecognition unit 58 adapted to recognize the type ofequipment 60 applied to theboom 18. Therecognition unit 58 can for example be based on RFID technology. - The
control system 48 further comprises one ormore sensors 62 for detecting the load on therear axle 16 of the vehicle. A plurality ofselectors - For example, a
selector 64 may be provided, for selection of the type ofequipment 60 in the case wherein therecognition unit 58 does not automatically recognize the type ofequipment 60 applied to theboom 18. Aselector 66 can also be provided which allows temporarily deactivating of the operation ofblock valve 44. - The
electronic control unit 50 receives signals from thesensors recognition unit 58 and from theselectors - The
electronic control unit 50 is programmed to control therelief valve 46 so as to limit the maximum speed of lowering of theboom 18 according to the type ofequipment 60, the load on theboom 18, the length L and angle α of theboom 18. - The
electronic control unit 50 limits the maximum speed of lowering of the boom with respect to the absolute maximum speed, in order to ensure that the vehicle operates in stable conditions regarding the risk of longitudinal overturning even under dynamic conditions. In particular, the limitation on the maximum lowering speed of theboom 18 enables the vehicle to be kept under safe conditions during the lowering manoeuver of theboom 18, which is the most critical from the point of view of the risk of longitudinal overturning. -
Figures 3 and4 show by way of example two load diagrams of thevehicle 10 with a different load P applied to theboom 18. The load diagram ofFigure 3 shows the working range of thevehicle 10 with a load P1 of 1500 Kg and the diagram ofFigure 4 shows the working range of the same vehicle with a load P2 of 3400 Kg. InFigures 3 and4 the diagrams relating to a vehicle operating with theforks 68 are shown. The load diagrams of thevehicle 10 vary depending on the type of equipment applied to the boom and as a function of the load applied to the boom. - In
Figures 3 and4 AMAX indicates the maximum work area of theboom 18, which represents the geometric coverage area of theboom 18. In the same diagrams AEFF indicates the actual work area with the load P1 or P2. The actual work area is reduced compared with the maximum work area with the increase of the load P. The maximum work area AMAX corresponds to the conditions in which the load P applied to theboom 18 is zero. - The actual work area AEFF is divided into work sub-areas with different maximum speeds, indicated with AEFF1, AEFF2, AEFF3, AEFF4 and AEFF5. The
electronic control unit 50 limits the maximum speed of lowering of theboom 18 in different ways according to the different work sub-areas. In the example illustrated inFigures 3 and4 in the work sub-area AEEF1 the maximum speed of lowering of theboom 18 is 100%, this means that in this subarea there is no limitation of the maximum speed of lowering of the boom and the lowering speed is equal to the maximum possible speed. In the graph ofFigure 3 , the subarea AEFF2 defines a work range in which the maximum speed of lowering of theboom 18 is equal to 75% of the maximum speed. In the sub-areas AEFF3 AEFF4 and AEFF5 the maximum speed of lowering of theboom 18 is, respectively, 50%, 25% and 10% with respect to the maximum speed. - In the graph of
Figure 4 , the work area AEFF2 has a maximum speed of lowering of the boom of 50% with respect to the maximum speed that it has in the area AEFF1. The work sub-areas AEFF3 and AEFF4 have, respectively, maximum speeds of lowering of the boom of 25% and 10%. Outside of the work area AEFF the lowering speed of the boom is zero. If the vehicle were to be found to operate outside of the actual work area AEFF for the load conditions and for the type of equipment installed, the operator must reduce the length of the boom to return to the conditions in which a manoeuvring speed of the boom is possible. - As already said the diagrams of
Figures 3 and4 vary depending on the load P and depending on the type of equipment installed on the vehicle. These diagrams also vary depending on the type of vehicle. The diagrams ofFigures 3 and4 have been provided purely for guidance in order to understand, on a qualitative level, the operation of the system according to the invention. The actual work areas for the type of vehicle, for the type of equipment installed and for the different loads P are determined experimentally in order to maintain thevehicle 10 under conditions of dynamic stability with regard to the risk of longitudinal overturning during the lowering manoeuver of theboom 18. - Of course, without prejudice to the principle of the invention, the details of construction and the embodiments may be widely varied with respect to what is described and illustrated without thereby departing from the scope of the invention as defined by the claims which follow.
