Rotatable and articulated material handling apparatus
A material handling apparatus for mounting on a support structure. The material handling apparatus comprises a telescopic riser portion coupled to the support structure. A telescopic boom portion is coupled to the riser portion. A telescopic jib portion is coupled to the riser portion. A hook is coupled to the jib portion. A control apparatus is coupled to each of the riser, boom, and jib portions. Wherein, each of the telescopic portions can be independently, selectively moved in a push-pull mode to manipulate material.
1. A land vehicle having a material handling apparatus, comprising:
a support structure coupled to a plurality of weight bearing elements;
a cab coupled to the support structure;
a riser having a first telescopic actuator, the riser coupled to the support structure;
a boom having a second telescopic actuator, the boom coupled to the riser;
a jib having a third telescopic actuator, the jib coupled to the boom;
a hook coupled to the jib;
a first hydraulic actuator coupled to the support structure and the riser;
a second hydraulic actuator coupled to the riser and the boom;
a third hydraulic actuator coupled to the boom and the jib;
a control apparatus coupled to the actuators and operable to move the riser, the boom, and the jib in a telescoping mode and an articulating mode to manipulate material coupled to the hook.
2. The land vehicle of claim 1 , wherein the weight bearing elements comprise wheels.
3. The land vehicle of claim 1 , wherein the control apparatus is operable from the cab.
4. The land vehicle of claim 1 , including a fourth hydraulic actuator coupled to the jib and the hook and operable to articulate the hook.
5. The land vehicle of claim 1 , wherein the telescopic actuators are selected from a group including a hydraulic machine, a pneumatic machine, and an electric motor.
6. The land vehicle of claim 1 , wherein the control apparatus is operable at a location remote from the cab.
7. The land vehicle of claim 1 , including an outrigger assembly coupled to the support structure.
