’S
Mechanical Dock Leveler Hydraulic Conversion provides a practical alternative to
applications where “basic automatic operating characteristics” are desired. The unit is operated by a
single, remote pushbutton control box. An electro-hydraulic power unit delivers hydraulic oil to heavy
duty cylinders for platform and lip operation. It also includes an emergency safety system which
restricts uncontrolled platform drop.
Materials required for installation (not provided).
1. 1 to 1.5 gallons of MIL- H-5606 Hydraulic Fluid
2. (8) 5/8” x 4” (minimum) concrete anchors
3. Teflon plumbers tape
4. Grey paint
5. Shim steel to lock in movable rear hinge
(if necessary)
6. Electrical Cord / Conduit
Tools Needed
