Abstract

A process of handling a frame of a vehicle and an apparatus for a lift truck for handling a frame of a vehicle. The apparatus includes a support frame operatively connected to and cantilevered from the lift truck and a carriage suspended from the support frame. The carriage includes at least two oppositely acting depending arms for handling the vehicle frame.

Claims

1. An apparatus for a lift truck for handling a frame of a vehicle, the apparatus comprising:

a support frame operatively connected to and cantilevered from the lift truck, said support frame including a lower frame, an upper frame and brace members, said brace members connected to said lower frame for supporting said upper frame in a raised position and cantilevered from the lift truck;

a carriage suspended from said upper frame by chain segments secured to said upper frame and to said carriage to allow said carriage to shift and sway, said carriage including at least two pairs of oppositely acting depending legs having feet members which extend laterally from said legs to engage an underside of the frame for handling the vehicle frame, said legs pivot about two parallel spaced cross members which are suspended from said support frame, said pairs of legs being connected by a cross brace which is actuated by a hydraulic device which extends between and connects said opposing pairs of legs.

2. The apparatus of claim 1 wherein said lower frame of said support frame includes two generally parallel elongated members, said elongated members each having an opening sized and positioned to receive a fork of the lift truck.

3. The apparatus of claim 2 wherein said upper frame includes two spaced parallel support members and a cross piece member perpendicular to said support members connecting said support members to maintain said support members in a parallel position.

4. The apparatus of claim 1 wherein said brace members extend between said upper frame and said lower frame, said brace members position said upper frame in a fixed elevated position a selected distance from said lower frame such that said upper frame is cantilevered from said lower frame and the lift truck.

5. The apparatus of claim 1 wherein said legs extend downward from and are pivotally secured to cross members and are actuated by a hydraulic device which connects said legs.

6. The apparatus of claim 5 further comprising a stop mechanism to limit the range of pivotal movement of said legs.

7. The apparatus of claim 6 wherein said stop mechanism includes a bolt threaded through a plate attached to said cross piece member such that by adjusting said bolt depth within said plate the range of movement of said legs may be varied.

8. A lift truck having an apparatus for handling a frame of a vehicle, the lift truck comprising:

forks mounted for vertical movement on a mast structure attached to said lift truck.

a support frame operatively connected to and cantilevered from said forks, said support frame including a lower frame, an upper frame and brace members, said brace members connected to said lower frame for supporting said upper frame in a raised position and cantilevered from said lift truck; and

a carriage suspended from said upper frame by chain segments secured to said upper frame and to said carriage to allow said carriage to shift and sway, said carriage including at least two pairs of oppositely acting depending legs that pivot about two parallel spaced cross members which are suspended from said support frame, said pairs of legs being connected by a cross brace which is actuated by a hydraulic device which extends between and connects said opposing pairs of legs for handling the vehicle frame.

9. The apparatus of claim 8 wherein said lower frame of said support frame includes two generally parallel elongated members, said elongated members each having an opening sized and positioned to receive a fork of said lift truck.

10. The apparatus of claim 9 wherein said upper frame includes two spaced parallel support members and a cross piece member perpendicular to said support members connecting said support members to maintain said support members in a parallel position.

11. The apparatus of claim 8 wherein said carriage includes at least two cross members and at least two oppositely acting legs, said legs having feet members which extend laterally therefrom and engage the underside of the frame.

12. The apparatus of claim 8 further comprising a stop mechanism to limit the range of pivotal movement of said legs.
