INSTALLATION
8. Installation of platform to carriage.
A. Lower the RRH platform down centering
the platform hinge tubes with the carriage
pins. (Care should be taking to prevent
damage to hoist cylinder rod ends).
B. Lube (C) rear hinge pins using grease.
Install the hinge pins in the carriage embed
only through out the first hinge tube.
C. Fully insert the hinge pins. Start with the
outer left side outside first and work your way
to the other end.
D. Install and secure cotter pins into the end
of the hinge pins.
E. Make all hydraulic hose(s).
9. Make all electrical connection.(Only after all
welding is completed and touched up.)
10. DO not connect (B) hoist cylinders(s) at this time.
The system must be bled before connected see
(page 19).
Installation of RRH levelers from inside is
recommended due to combined height of leveler
and proper lifting equipment may be greater than
outside door height.
ALWAYS disconnect electrical power source and
ground wire before welding on dock leveler.
DO NOT ground welding equipment to any hydraulic
or electrical components of the dock leveler. Always
ground to the dock leveler frame.
Overall length of lifting chain and bracket must be
kept to a minimum to prevent interference
between the lifting equipment and the building
ceiling or door as the dock leveler is lowered into
the pit.
