Definitions

  • This invention is a mobile carrier with a vertical and horizontally controllable crane for a work station or bucket, often referred to as a "cherry picker", which apparatus is particularly adapted for the clearing of power line right-of-ways of tree limbs and brush. More particularly this invention is concerned with an improvement of such known bucket platforms of this type, the improvement residing in a means to horizontally move the crane laterally from the side of the carrier, usually a truck, underneath a power line so that the work station can be raised upwardly on the other side and moved side-to-side to permit limbing. By moving the crane in under the power line the effective reach of the crane can be increased 30 to 50% or more.
  • This apparatus can also be used for placing and repair of power and telephone lines in a known manner.
  • the present invention is the carrier for a work station or bucket and its supporting crane which comprises a vehicle and mounted to the chassis of the vehicle a laterally extensible platform carrying the bucket crane which platform can be extended telescopically out from the side of the vehicle 10 to 15 feet or so.
  • a laterally extensible platform carrying the bucket crane which platform can be extended telescopically out from the side of the vehicle 10 to 15 feet or so.
  • this invention is a mobile horizontally and vertically adjustable carrier and work station comprising a transport means such as a truck having a chassis.
  • An extensible platform is carried by the chassis and is adapted to telescope in and out from the truck laterally to the line of travel of the truck.
  • the extensible platform has extensible stabilizers or outriggers on either side, approximately midway when it is extended, that are adapted to be dropped down to contact the ground and support the platform when it is extended.
  • An articulated crane of conventional construction is rotatably supported by the extensible platform at its outboard end. As is customary the crane has at least two joints.
  • the upper end of the crane, or boom carries a work station or bucket that can hold a worker.
  • the extensible platform can be moved in and out by means of electrically powered screws it is preferred to operate by hydraulic power.
  • the extensible platform consists of three telescoping sections operated hydraulically for extension and retraction.
  • the rotating base and crane can be of conventional construction.
  • it can be a Versilift VO-50 manufactured by Time Manufacturing.
  • the crane and rotation mechanism are operated hydraulically.
  • the hydraulic power for both the extensible platform and the crane can be supplied from the truck in a known manner.
  • the stabilizers attached to the extensible platform preferably are capably of being extended laterally from each side of the platform before the feet are dropped down to contact the ground.
  • the stabilizers can also be operated hydraulically although mechanical screws could also be used to accomplish the outward extension of them and the downward placement of the feet. If the platform is 4 feet or so wide and the stabilizers each can be extended at least another 2 feet this gives a good 8 foot wide very stable base for supporting the crane and bucket in addition to the stability imparted by having the platform mounted to the chassis of the truck.
  • a particular advantage of this invention resides in the fact that the trend in the industry has been to go to larger cranes - ones that will reach 90 to 100 feet. Such equipment is usually maintained in good mechanical order. These operators have been loath to purchase the far more expensive, larger cranes.
  • the present invention ameliorates this problem in that the laterally extensible platform permits the smaller canes to continue to be used and to just as effective as the larger ones when the latter are used in the conventional manner to reach over the power lines.
  • a truck 10 has a chassis 11 to which is mounted the laterally extensible platform 12 of this invention.
  • the truck at the rear end may have a carrier 13 of some sort, such as one to receive wood chips.
  • the telescoping platform consists of three sections.
  • the main one 14 slides in and out of mounting bracket 15 affixed to the truck chassis.
  • Sections 16 and 17 extend therefrom.
  • the outboard section 17 has mounted to it, for rotation, the crane base 20 which in turn carries crane arm 21, boom 22 and work station or bucket 23.
  • the crane is operated by hydraulic cylinders 24 and 25.
  • Items 20 - 25 are commercially available and operated in a known manner with hydraulic power supplied from truck 10.
  • the platform will be extendable at least 10 feet and can be designed to extend 15 to 20 feet or more depending on the number sections utilized.
  • Stabilizers 31 and 32 are carried at the outboard end of the first platform section 14. When the apparatus is collapsed for travel the feet 33 and 36 of the stabilizers are retracted and the stabilizers nestle against the side of the truck as shown in Figs. 1, 2 and 3. In operation, after the platform 14 is extended the two stabilizers 31 and 32 are extended outwardly by arms 34 and 35 and feet 33 and 36 are lowered to contact the ground and stabilize the platform. This may be done hydraulically or more simply by manually pulling them out and pinning and allowing the legs to drop and pinning.
  • Fig. 6 is a perspective view of the apparatus of this invention.
  • a truck 50 is parked along side the road next to a power line 60.
  • Extensible platform 51 is extended laterally from the side of the truck outwardly under the power lines. It carries the crane bucket generally indicated at 52.
  • the worker or operator 53 rotates, elevates and positions the crane from controls within the bucket in a known manner to position himself to cut the limbs of tree 54 which might damage power line 60.
  • the whole of the system can be retracted to the truck bed and the truck moved to the next station between the power line poles.
  • Fig. 8 is a cross section of the beams on the left side when the platform is collapsed.
  • Channel beams 71 and 72 are braced by cross member 73 and attach to the truck body.
  • Nestled and sliding within these beans are channel beams 75 and 76 of the first stage.
  • Nestled and sliding within beams 75 and 76 are channel beams 77 and 78 of the second stage and, finally, nestled and sliding within beams 77 and 78 are box beams 79 and 80.
  • the box beams end in cross box beams 81 and 82.
  • a metal plate 83 Inset within the box beams is a metal plate 83 having an opening 84 to receive the crane.
  • a cross plate 74 is attached to the inner ends of beams 75 and 76 to space them and to receive the impetus from twin hydraulic pistons 91 and 92 the ends of which are held by cross member 93, attached to the underside of beams 71 and 72.
  • a two stage hydraulic piston 94 the ram of which is attached to box member 82, serves to extend and collapse the second and third stages of the platform.
  • Top surfaces for the spaces between beams 71 and 72, and 75 and 76 are indicated at 101 and 102 respectively.
  • Plastic glides as illustrated at 95, 96 and 97 extend along the bearing surfaces of beams 71, 72, 75, 76, 77 and 78. These tighten the assembly and help provide a smooth action.
  • the glides can be made of a polytetraflouroethylene, a polyester or similar material.
  • hydraulic cylinders 91 and 92 are activated and push out the first stage members 75 and 76.
  • Outriggers 87 and 88 are then hydraulically extended and legs 90 and 100 are hydraulically extended to the ground.
  • hydraulic piston 94 is activated pushing out the third stage which carries with it the second stage. Stops (not shown) prevent one stage from sliding out of its supporting stage. Retraction is accomplished by reversing the above steps.
