Abstract
An improved counterbalancing structure for counterbalancing a material handling machine having an elevated operator compartment wherein the counterbalancing counterweight is picked up by means of a material handling structure carried on lift arms at one end of the machine. The counterweight is provided with an upper hooking portion which is disposed in the line of sight of an operator in a normal operating position in the operator compartment with the lift arms and material handling structure being disposed below the line of the sight of the operator in a lowermost pickup position thereof. The counterweight may include a weight portion having a low center of gravity. The upper hooking portion may be defined by a bracket portion of the counterweight extending substantially upwardly from the weight portion thereof. The material handling structure of the machine may be provided with an upwardly projecting bracket which is similarly in the line of sight of the operator during the counterweight pickup operation.
