HOW TO SUPPORT THE DOCK LIFT DURING ROUTINE
MAINTENANCE AND INSPECTION
Figure 10: How to Support the Dock Lift for
Maintenance
ARC FLASH AND SHOCK HAZARD PPE (PERSONAL PROTECTION EQUIPMENT)
REQUIRED. DE-ENERGIZE EQUIPMENT BEFORE WORKING ON OR INSIDE. DO
NOT OPEN COVER WITHOUT APPROPRIATE PPE. REFER TO NFPA 70E FOR PPE
REQUIREMENTS. THIS PANEL MAY CONTAIN MORE THAN ONE POWER SOURCE.
HAZARDOUS VOLTAGE WILL CAUSE SEVERE INJURY OR DEATH.
NEVER GO BENEATH THE DOCK LIFT FOR ANY REASON UNLESS THE PLATFORM
AND HINGED BRIDGE(S) ARE PROPERLY SUPPORTED (SEE “Figure 10: How
to Support the Dock Lift for Maintenance” on page 15) AND THE POWER IS
DISCONNECTED, PROPERLY TAGGED AND LOCKED OUT. IT IS THE RESPONSIBILITY
OF THE OWNER TO ENSURE THAT NO LOAD OR TRAFFIC IS PLACED ON THE
PLATFORM WHILE THE MAINTENANCE STAND IS ENGAGED. THE CONSTRUCTION
OF THE MAINTENANCE STAND IS INTENDED TO SUPPORT THE WEIGHT OF THE
UNLOADED DOCK LIFT ONLY.
BEFORE DOING ANY INSTALLATION, MAINTENANCE, INSPECTION OR TROUBLE
SHOOTING, BARRICADE ALL AREAS FROM TRAFFIC AROUND THE WORK AREA
INSIDE (& OUTSIDE IF APPLICABLE) FOR SAFETY, POST APPROPRIATE WARNING
SIGNS AND BE CERTAIN THAT THE POWER IS DISCONNECTED, PROPERLY TAGGED
AND LOCKED OUT. ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED
ELECTRICIAN IN ACCORDANCE WITH ALL APPLICABLE CODES AND REGULATIONS.
THE BLOCKING PROCEDURES DESCRIBED BELOW ARE SUITABLE ONLY FOR THE
INSPECTION, TROUBLE SHOOTING AND MAINTENANCE PROCEDURES DESCRIBED
IN THIS MANUAL. THEY MAY NOT BE SAFE FOR OTHER INSPECTION, MAINTENANCE
AND REPAIR PROCEDURES THAT MAY BE REQUIRED. CONTACT YOUR AUTHORIZED
PENTALIFT REPRESENTATIVE FOR DIRECTION PRIOR TO UNDERTAKING ANY ACTIONS OTHER THAN THOSE
DESCRIBED IN THIS MANUAL. FAILURE TO PROPERLY ADHERE TO LIFT BLOCKING PROCEDURES IS TO
RISK THE SUDDEN AND UNCONTROLLED DESCENT OF THE LIFT DURING MAINTENANCE OR INSPECTION. A
FALLING LIFT CAN CAUSE SEVERE INJURY OR DEATH.
ONLY TRAINED AND QUALIFIED PERSONNEL SHOULD PERFORM INSPECTION OR
MAINTENANCE AND SERVICE PROCEDURES.
PRIOR TO PERFORMING ANY ACTIVITY WITHIN THE OPERATING PATH OF THE DOCK
LIFT, ALWAYS ENSURE THAT THERE IS NO LOAD ON THE DOCK LIFT AND THAT THE
INSTRUCTIONS LISTED BELOW ARE FOLLOWED.
NOTE: ANY LOADS INCLUDING LOADING/UNLOADING
EQUIPMENT, ETC., ARE TO BE REMOVED.
The blocking procedure is as follows:
1.
Raise the unloaded dock lift to its maximum height.
2. At the rolling end of the dock lift, the swing away
maintenance stand pivots on a pin. Swing the
maintenance stand as far around as possible into the
path of the rollers. (See “Figure 10: How to Support the
Dock Lift for Maintenance” on page 15)
3. Lower the dock lift until the leg rollers are securely
supported by the maintenance stand(s). Confirm the
scissor legs are now securely blocked from downward
movement.
4. Disconnect, properly tag and lock out power to the dock
lift prior to commencing inspection, trouble shooting or
maintenance.
