the trucks are danbach vna running with 700-ah chloride or hawker batteries no change over.
the dust is mostly from cardboard the area is industrial so its a naturally dusty environment anyway.
re abuse the trucks are used in a cramped location so strike damage occurs usually to the rotate stops or wire guidance sensors if our drivers are negilgent we deal with it but the units are certainly not caressed and the operators are sometimes temporary so so ownership care is difficult.
the reason i ask about running up time is our maintainance company attempts to keep above 80% (they tell me thats good) and i wanted to bench mark check with someone who's independand.
