introduction:Summary of electric forklift classification The electric stacker is a kind of light lifting and stacking equipment for indoor use,Relatively light body,The lever arm of the counterweight is lengthened by the support arm at the front of the body,To balance the load。Because the fulcrum is outside the center of gravity of the load,The counterweight lever is much larger than the load lever,So a smaller counterweight can lift a larger load。Electric stacker with timeless forceEJC 14Take... for example,Rated load1.4Tons of,And self-weight only955kilogram,Vehicle length、Vehicle width、The turning radius is correspondingly smaller,Jungheinrich also has its patented slow button device,Allows slow operation in the upright braking position
