SELF-LEVELLING MECHANICAL SYSTEM FOR A MATERIAL HANDLING DEVICE
First Claim
1. A material handling device comprising:
- (a) a support trailer configured for movement thereof;
(b) a material holding device pivotally connected to the support trailer, the material holding device configured for reversible rotational movement between a first lowered orientation and a second elevated orientation;
(c) an accessory support pivotally connected to the material holding device, wherein the accessory support is coupled to the material holding device at a location wherein the accessory support translates when the material holding device is reversably moved between the first lowered orientation and the second elevated orientation; and
(d) a linkage system operatively interconnecting the support trailer, the material holding device and the accessory support, wherein the linkage system is configured to substantially maintain a desired orientation of the accessory support during reversible rotational movement of the material holding device.
