Access to the area beneath the raised carriage deck can be gained through manual
measures implemented by qualified maintenance technicians or automatically through the
use of a factory supplied option known as maintenance mode.
1. Call the carriage to the lower level.
2. Open the lower gate and bypass the gate open switch at the interlock or in the main
control panel. If there is any confusion about how to do this, call the PFlow Industries,
Inc. Product Support Department.
3. Barricade the lower level gate opening to prevent unintended access and provide
hazard warning signs.
4. Verify that the carriage is empty. Raise the carriage to the upper level making sure all
personnel are clear of the moving carriage.
5.
Lockout the lift in accordance with the facility Lockout/Tagout program.
6.
Secure the carriage at the upper level using adequately sized maintenance chains,
maintenance pins, or straps with shackles around the drivebase that are capable of
supporting the weight of the carriage to provide additional safety.
Do not attempt to do any work on the lifting system (e.g., hydraulic system, motor drive).
When work is to be done on the hydraulic system or mechanical drive system, a different
procedure must be followed. The carriage must be landed on stands or secured by another
means in order to prevent any weight from relying on the lifting means or when the
hydraulic pressure is fully relieved. Consult Factory.
7. Return to the lower level and verify that the gate and the carriage does not move if the
push-buttons are pressed. Wedge or block the lower level gate in the open position to
prevent the gate from closing while someone is in the pit area.
8.
Perform the necessary maintenance, adjustments, or cleaning under the carriage.
9.
Exit the pit and remove the wedge or block holding the lower level gate open.
10.
Reverse the process to return the VRC into service.
NOTICE
If the VRC is equipped with this option, refer to Maintenance Mode Sequence of Operation
Bulletin #15879-0009 for details.
