The EH dock leveler uses hydraulic logic and

one-button operation for ease of use.

The dock leveler can be operated remotely using the

RAISE button (M) on the control panel .

Platform (C) is raised by pushing and holding the

RAISE button (M). This activates an electric motor

(E) which, in turn, drives a hydraulic pump. The

hydraulic pump forces oil into the platform cylinder(s)

(F), causing the platform to rise. Releasing the

RAISE button allows the platform to lower.

When the platform rises to the highest point of

travel left in the platform cylinder, valving in the

Powerpack directs fluid flow to the lip cylinder,

extending the lip.

With the lip fully extended, the raise button may be

released, allowing the leveler to float down on to the

truck for loading or unloading.

*See Operating Instructions for a complete operation

guide.
