Abstract
A method and apparatus for a hoist system for a vehicle is provided. The hoist system includes a support frame mounted to the vehicle. A slidably extendable pair of parallel rails are mounted to the support frame. The front ends and the tail ends of the parallel rails can be connected. A crossbeam that supports a hoist mechanism is slidably suspended from the pair of rails. The support frame can be collapsibly hinged for transport. The support frame is mounted to the vehicle, at a height above the cab of the vehicle or alternatively incorporated into the ladder rack of the vehicle. The hoist system is light-in-weight with a versatile support frame that can transfer heavy and swinging or shifting loads. The hoist system is also heavy-duty and has an extended and side-to-side reach.
Claims14
A hoist system for a vehicle, which includes:
- a support frame mounted to the vehicle,
- the support frame having a first rearward member and a second rearward member,
- the first rearward member having a first lower pin,
- the second rearward member having a second lower pin;
- a slidably extendable first rail mounted to the support frame,
- the first rail having a first front stop pin and a first rear stop pin;
- a first support bar, attachable to between the first lower pin and the first rear pin;
- a slidably extendable second rail mounted to the support frame,
- the second rail having a second front stop pin and a second rear stop pin;
- a second support bar, attachable to between the second lower pin and the second rear pin;
- the second rail mounted in parallel relation to the first rail;
- a hoist mechanism;
- and
- a two ended mobile crossbeam for slidably supporting the hoist mechanism,
- the two ended mobile crossbeam having a first end slidably mounted to the first rail, and
- the two ended mobile crossbeam having a second end slidably mounted to the second rail,
- the first support bar supports the first rail and prevents sliding movement of the first rail;
- and
- the second support bar supports the first rail and prevents sliding movement of the second rail.
A method of a transferring a load, which includes:
- mounting a support frame to a vehicle;
- mounting a slidably extendable first rail to the support frame;
- mounting a slidably extendable second rail to the support frame, the second rail
- mounted in parallel relation to the first rail;
- slidably attaching a mobile crossbeam to the first rail, the mobile crossbeam having a
- first end and a second end;
- slidably attaching the second end of the mobile crossbeam to the second rail;
- slidably supporting the hoist mechanism from beneath the mobile crossbeam;
- lifting the load with the hoist mechanism;
- providing the support frame with a first rearward member including a first lower pin and a second rearward member including a second lower pin;
- attaching a first support bar, connecting the first lower pin to the first rear stop pin;
- attaching a second support bar, connecting the second lower pin and the second rear stop pin;
- preventing sliding movement of the first rail with the first support bar;
- and
- preventing sliding movement of the first rail with the second support bar support.
A hoist system for a vehicle having a cab, which includes:
- a support frame mounted to the vehicle, at a height above the cab of the vehicle;
- a slidably extendable first rail mounted to the support frame;
- a slidably extendable second rail mounted to the support frame,
- the second rail mounted in parallel relation to the first rail;
- a slidable hoist mechanism;
- a two ended mobile crossbeam for slidably supporting the hoist mechanism,
- the two ended mobile crossbeam having a first end slidably mounted to the first rail, and
- the two ended mobile crossbeam having a second end slidably mounted to the second rail;
- the support frame including a first rearward member and a second rearward member;
- the first rearward member has a first lower pin;
- the second rearward member has a second lower pin;
- the first rail has a first front stop pin and a first rear stop pin;
- the second rail has a second front stop pin and a second rear stop pin;
- a first support bar, attachable to between the first lower pin and the first rear stop pin;
- a second support bar, attachable to between the second lower pin and the second rear stop pin;
- the first support bar supports the first rail and prevents the sliding movement of the first rail;
- and
- the second support bar supports the first rail and prevents the sliding movement of the second rail.
