That’s a very common question that is raised when decisions are made related to dock leveler selection.
Mechanical dock levelers use a series of springs and levers to raise the platform and extend the lip assembly. The mechanical dock leveler is then “walked down” into position on the delivery truck bed.
Hydraulic dock levelers, though structurally the same, use a push button control to operate the dock leveler. When the button is pushed, an electric motor starts and a hydraulic cylinder is used to raise the platform. A second hydraulic cylinder is used to extend the lip assembly. When the dock attendant releases the control button, the dock leveler automatically lowers into position on the truck bed.
Mechanical dock levelers are more cost effective at time of purchase.
Hydraulic dock levelers cost more to purchase, however require less maintenance and are more ergonomically accepted.
