First Claim
Patent Images
1. A method for maximizing and varying a counterweight load on a variable counterweighing device attachable to a material handling machine, said method comprising:
- A variable counterweighing device attachable to a material handling machine, said variable counterweight device comprising a guide track, said guide track having extendable length, said guide track having one or more straight, angled or curved portions, a moving track held within said extendable guide track, a plurality of individual counterweight members attachable to said moving track, said moving track attached to a rotary axle connected to a drive device, said drive device connected to an energy source;
The method for maximizing and varying a counterweight load on said variable counterweighing device wherein individual counterweight members of said plurality of individual counterweight members are hingely and pivotally connected to said moving track, each connected individual counterweight member being adjacently positioned next to another connected individual counterweight member on said moving track without obstruction with each other such that any attached individual counterweight member may pivot freely at said hinged connection and be transferred in an unobstructed manner through angled or curved portions of said guide track in variable manner.

4. A versatile counterweighing system for counterweighing a material handling machine with movable boom, said system comprising:
-
A variable counterweighing device comprising a guide track, said guide track having extendable length, said guide track having one or more straight, angled or curved portions, a moving track held within said extendable guide track, a plurality of individual counterweight members attachable to said moving track, said moving track attached to a rotary axle connected to a drive device, said drive device connected to an energy source; Wherein said plurality of individual counterweight members is further comprised of at least a parent layer and attachable secondary layers, said parent layer comprising individual counterweight members hingely connected to said moving track in a nonobstructive manner and said attachable secondary layers comprising individual counterweight members connected to an exposed surface of a connected member of a prior layer, the connected individual counterweight members of the various layers having a size and shape dimension that allows the connected counterweight members of the parent layer to pivot freely at said hinged connection and be transferrable in an unobstructed manner through angled portions of said guide track without obstruction by connected individual counterweight members of any attached layer; Wherein the guide track of said counterweighing device is attached to a first side surface of said material handling machine and is continuously extendable to one or more additional adjacent side surfaces of said machine such that the moving track held within said guide track moves forward and rearward in variable manner between multiple adjacent sides of said material handling machine; Said versatile counterweighing system wherein said counterweighing device being further connected to a control unit and one or more sensors for monitoring and directing the load position of said individual counterweights relative to the load position of said material handling machine to achieve a desired counterweighing effect.
