Abstract

Abstract A construction vehicle has a rear bumper assembly mounted on a frame thereof. The bumper assembly comprises a horizontally disposed bottom plate and a plurality of upstanding plates which define a closed compartment having a counterweight disposed therein. The counterweight is attached to the bottom plate by a spacer which extends through the center of gravity of the counterweight and by a pair of bolts attached to opposite ends of the spacer. The counterweight is assembled by attaching a lifting eye to the spacer, lowering and simultaneously centering the counterweight in the compartment, replacing the lifting eye with one of the above-mentioned bolts and attaching the other bolt to the spacer.

Claim 14
Independent Claim 107 words
A method for mounting a counterweight in a compartment defined in a bumper assembly for a vehicle comprising the steps of threadably attaching lifting means to an upper side of said counterweight, lifting said counterweight by said lifting means over said compartment, lowering and simultaneously self-centering said counterweight in said compartment, securing said counterweight to said bumper assembly by replacing said lifting means with a bolt threadably attached to the upper side of said counterweight and duplicating said attaching, lifting, lowering and securing steps to mount a second counterweight in a second compartment defined in said bumper assembly in laterally spaced relationship relative to said first-mentioned counterweight.
Claim 15
Independent Claim 107 words
A method for mounting a counterweight in a compartment defined in a bumper assembly for a vehicle comprising the steps of threadably attaching lifting means to an upper side of said counterweight, lifting said counterweight by said lifting means over said compartment, lowering and simultaneously self-centering said counterweight in said compartment, securing said counterweight to said bumper assembly by replacing said lifting means with a bolt threadably attached to the upper side of said counterweight and duplicating said attaching, lifting, lowering and securing steps to mount a second counterweight in a second compartment defined in said bumper assembly in laterally spaced relationship relative to said first-mentioned counterweight.
Claim 16
Dependent Claim 26 words
The method of claim 13 wherein said lifting step comprises applying a lifting force to said counterweight at least approximately at the center of gravity thereof.
Claim 17
Dependent Claim 25 words
The method of claim 13 wherein said lowering and centering steps comprise interengaging mating frustoconically shaped surfaces defined between said counterweight and said bumper assembly.
Claim 18
Dependent Claim 20 words
