Definitions

  • a hydraulically operated traveling crane includes a chassis or support constructed and arranged to permit the crane to be operated with a lattice boom or with a telescopic boom.
  • the carrying chassis includes plates which are mounted on a base and which include an inclined front wall with a pivot bearing at the lower end for either the lattice boom or for a whipping cylinder for a telescopic boom.
  • the upper end of the inclined front edge provides a rotatable support for a pivot journal for a backdrop support for the lattice boom or for the pivotal support for the telescopic boom.
  • the mounting plates on the carrying chassis include a rearward extension providing a rotatable support for two rotatable pulleys of the hoisting gear around which connecting cables for the telescopic boom or the lattice boom or an extension of either may be connected.
  • the mounting platform of the chassis provides means for mounting a support plate for cable winches which are employed with the lattice boom and these may be easily removed when the telescopic boom is positioned on the chassis.
  • the cable winches include the cable lines which are provided for raising and adjusting the lattice boom.
  • a pump unit for the hydraulic controls is arranged below the rearward extension mounting the cable winches.
  • Guide pulleys for the boom cables are advantageously mounted on a combining unit which includes an adjustable triangular plate member mounting the pulleys.
  • a hydraulic traveling crane which includes a fulcrum for a telescopic boom and a separate fulcrum for a lattice boom which are arranged at each end of the upper carrying chassis and which may be employed for the selective attachment'of one or the other boom as well as for the attachment of hydraulic cylinders on the upper carrying chassis for raising and adjusting the boom which is attached.
  • Such a known traveling crane has a particular disadvantage that its backdrop support for the lattice boom is not designed to prevent it from toppling over.
  • lattice boom is also shifted and held by hydraulic cylinders, though the use of a traveling crane equipped with lattice booms is accomplished as a rule over longer periods of time and unavoidable oil leak losses make it impossible to hold a boom for a longer period in a certain position.
  • the varying angular velocity and shifting movements of particularly long lattice booms hardly permits fine adjustments in assembly operations.
  • Another disadvantage of this embodiment is that the great number of levers and rods as well as the shifting cylinders for the boom greatly limit the width of the cable drums for the load hoisting gears in a traveling crane with a lattice boom, and so the cable-receiving capacity of the cable drums and thus the load lifting heights are very limited, particularly when long lattice booms and adjustable long telescopic booms are employed.
  • a particular disadvantage of the known traveling crane construction with a telescopic boom is that the load winch is arranged in front of the boom, and is thus on the same side on which the load acts on the platform support, so that the boom and its shifting mechanism are subjected to additional loading forces by the cable line of the load winch.
  • a design of a hydraulic traveling crane which includes a chassis for mounting a lattice boom or telescopic boom.
  • the mounting arrangement for either the telescopic or the lattice boom is such, that either boom may be used with the same possibilities of operation and the same safety of operation as a hydraulic traveling crane equipped specifically with only a lattice boom or with only a telescopic boom.
  • the inventive construction includes a rotatable mounting platform carrying an upstanding support structure which includes an inclined front wall providing a journal at its lower end for the lattice boom or the whipping cylinder for the telescopic boom.
  • the support structure also carries a journal at its upper end which may be provided for either the backdrop support for the lattice boom or for the pivotal support of the telescopic boom.
  • the whipping cylinder for raising and adjusting the telescopic boom is articulated to the lower pivotal support and to the associated telescopic boom.
  • the construction includes a rearward extension of the support plates which provide a mounting for the rotatable pulleys for drums of the cable winches.
  • a rearward extension of this part provides a means for mounting the guide pulleys for the lattice boom.
  • the cable winches and the necessary guide rollers for operating the crane with a lattice boom are also carried on a chassis by the forward location adjacent the support for the two pivot journals.
  • the lattice boom may be held safely in any position by self-locking brakes installed on the cable winches.
  • the arrangement is such that very wide cable drums may be provided for the cable winches, so that even long booms and, if necessary, with extension booms, can be used on a mounting chassis.
  • the winches for the lattice boom are advantageously secured on an upstanding bracket which is mounted on the chassis platform in a manner such that it may be easily removed when the telescopic boom is to be employed. These control winches can, of course, be left on the platform if desired, when the telescopic boom is installed instead of the lattice boom.
  • a particularly space-saving arrangement for the load hoisting gears, and which also enhances the carrying capacity of the crane, is attained when they are arranged at the ends of bearing plates secured as brackets on the platform of the upper carrying chassis, or on adjoining winch plates which are secured by means of welds, or securing screws. In the latter case, they are carried on plates which project toward the rear and in the case of a Diesel engine pump unit for the hydraulic plant, they can be arranged underneath the projections of the winch plates, and thus underneath, the load hoisting gear where they provide a counterweight for the operation of the device.
  • the hydraulic control and driving elements which are carried on the crane are identical for use either with a telescopic boom, or with a lattice type boom.
  • a type of fastening may be of advantage which permits the turning upwardly or downwardly of the various elements.
  • the boom is folded as usual, and the unit turns automatically downwardly, so that the height of the vehicle is reduced for transportation.
  • the load hoisting gears or the part thereof which may be provided for an extension boom are mounted so that they may be easily removed and can be replaced by a counterweight, in order to obtain the carrying capacity of the traveling crane by use of this counterweight.
  • a traveling crane which includes means for operating with a telescopic or lattice boom, and which comprises a mounting plate carrying a first pivotal journal for suspending a lattice type boom or a whipping cylinder for a telescopic boom, and a second pivotal journal located upwardly from the first forming a pivotal mounting for the telescopic boom or for a backdrop support of a lattice boom, and which advantageously includes a rear mounting plate portion carrying the hoisting drums or associated gearing.
  • a further object ofthe invention is to provide a hoisting crane which is simple in design, rugged in construction, and economical to manufacture.
  • FIG. 1 is a schematic side elevational view of a chassis of a hydraulic traveling crane having a lattice boom installed thereon and constructed in accordance with the invention

  • the platform 1 carries two spaced parallelupright mounting plates or bearing plates 6 which includes an oblique front edge 60.
  • a boom step bearing or mounting pin 2 is carried at the lower end of the front of each plate 6 and provides a pivotal mounting for either a lattice boom, generally designated 3, in FIG. 1, or a so-called whipping cylinder or fluid drive motor for raising and lowering a telescopic boom 30.
  • a higher pivot or abutment bolt 5 is supported by the plate 6 at a higher elevation and rearwardly of the pivot 2 and, it provides a pivotal support for either a backdrop support 4, as shown in FIG. 1, or for the telescopic boom 30, as shown in FIG. 2.
  • the bearing plate 6 includes a rearwardly extending upper portion which carries winch plates 7 which project rearwardly over a Diesel engine pump unit 17 for the hydraulic plant which is mounted on the platform 1.
  • the load hoisting gears or drums 8 and 9 are journalled in the winch plates 7, 7 and form a winch unit, generally designated 24, which is secured to the bearing plate 6.
  • the load hoisting gear 9 is provided for an extension boom which is not shown, but which can be used either with the lattice boom 3 or the telescopic boom 30.
  • the lattice boom 3 carries guide pulleys 3a and 312 at the outer end and a hook S8 is suspended on cable which extends back to the load hoisting gear 8.
  • the backdrop support 4 includes an adjustable threaded extension 40 which is pivotally connected to a pivot pin 62 carried on the lattice boom 3.
  • the lattice boom 3 also includes a diagonal brace 64 which is pivoted at a pivot pin 66 to the lattice boom 3 and which carries a puliey 68 at its outer end.
