When the Lift Carriage Must be Raised
BLOCKING INSTRUCTIONS
1. All loads must be removed from the lift platform prior to engaging the maintenance
devices. These devices are designed to support an unloaded lift only. Failure to
remove the load from the platform prior to blocking could cause the failure of the
maintenance devices and allow the lift to fall unexpectedly.
2. Raise the carriage to the desired elevation.
If Operational: Press the UP button and then press the EMERGENCY STOP
button when the desired height is reached
If Not Operational: Use a fork truck or other lifting device to raise the VRC
carriage, taking care not to damage the carriage or lift actuator/drive.
3. Place maintenance leg across the mast channel as shown in Figure 10. Make sure
the square tubing of the maintenance leg rests against the flange of the mast-beam.
4. Position the maintenance leg so that all of the alignment tabs fit over the flange of
The mast beam as shown.
Note: You should not stand beneath the carriage while setting the maintenance
device into position.
DANGER !
To avoid personal injury or death, check the stability of the supports. If there
is any chance of the support tipping or otherwise not providing a safe and
stable condition, do not go under the platform!
5. Lower the carriage platform onto the maintenance device.
If operational – either press the DOWN button or open the manual lowering
valve until the platform lands onto, and is fully supported by, the maintenance
device.
If NOT operational - Use a fork truck or other lifting device to lower the VRC
platform onto the maintenance devices, taking care not to damage the carriage
or lift actuator/drive. Make sure the platform is level when supported.
6. Re-check to ensure that the maintenance device is fully and properly engaged with
the underside of the platform. If the maintenance device is not fully engaged the lift
could fall unexpectedly, resulting in permanent damage to the device or the lift.
