LDL Dock Lift Owners Manual
This prevents personnel from standing upon or placing objects on the power unit.
Run the hydraulic lines from the power unit to the lift and flush with clean fluid before connecting the lines. If the lines
must be pushed through chases or enclosures, be sure to cap the lines to prevent contaminates from entering the
hose. Cleanliness is important in the maintenance of any hydraulic system.
6.
Remove all shipping bolts and hardware. (See “Figure 3: Moving the Dock Lift” on page 4).
7.
Connect the appropriate supply voltage to the motor control panel. (Refer to the
WIRING DIAGRAM
located inside
the motor control panel and the electrical specification label located on the side of the motor control panel).
NOTE: All wiring must be performed by a qualified electrician in accordance with all applicable codes.
NOTE:
a. On 3 phase units ensure phase polarity is correct. Incorrect polarity will cause the dock lift not to raise. The
motor will run backwards resulting in cavitation and possible damage to the pump.
b.
To prevent tripping the motor overload relay, the motor requires the specified voltage at the motor while the
motor is working under full load. If there is a problem, confirm that the supply conductors are sufficient in relation
to the run length. See Electrical Reference Chart. (Follow all applicable electrical codes as well.)
Ensure that the thermal overload relay is set to match the full load current as shown on the motor name plate. Follow all
applicable electrical codes.
