Dependent claims

A battery changing system for electric battery-powered vehicles, particularly for electric battery-powered underground mining vehicles having an axle and wheels supporting a main frame above a ground surface and a battery support attached to said main frame, and using exchangeable batteries, said battery changing system comprising:

a bellcrank connecting said battery support with said main frame;
a first pin mounting pivotably said bellcrank to said main frame;
a second pin mounting pivotably said battery support to said bellcrank;
an eyebar link connecting said battery support to said main frame in parallel with said bellcrank;
a third pin connecting pivotably said eyebar link to said main frame, said third pin positioned below said axle;
a fourth pin connecting pivotably said battery support to said eyebar link, and
means for pivoting said bellcrank around said first pin, whereby said battery support can be lowered to the ground.
