SAFETY DEVICES
DHOLLANDIA mobile column lifts are equipped with multiple safety devices in order to ensure that vehicles can be lifted with maximum
safety for the operator, any potential bystanders and the vehicle itself. The following safety devices are incorporated in the mobile
column lift:
1
Main power switch and indicator light : switch mounted on the electric control
box of the master column, enabling the operator to switch the main power to the
mobile column lift on / off. The indicator light indicates the status of the lift
accordingly.
2
Emergency stops: 2 switches mounted on the master and slave columns, enabling
the operator to immediately stop all electrically induced movements in case of
emergency.
After the emergency stop has been pushed, check:
whether anyone has been injured
whether damage has occurred to the mobile column lift or the vehicle.
3
Safety lock: 2 locks mounted on the master and slave columns, preventing that
the lift forks and the vehicle drift down in case of accidental loss of pressure in the
hydraulic circuit.
To avoid the risk of serious bodily injury or death of the operator or other bystanders
or property damage to the vehicle, the operator MUST ALWAYS engage the safety
lock as soon as the vehicle is raised to the desired elevation.
4
Electrical safety valves mounted on all cylinders: the safety valves lock the oil
inside the hydraulic cylinders as long as they are not energized via the electrical
controls. The purpose is to secure the lift forks in any given position, in case of
accidental failure of a hydraulic pipe (as soon as the electrical controls are
released).
DHOLLANDIA safety valves are equipped with a manual emergency control,
allowing the operator or repair agent to open the valve manually in case of electrical
failure (see MAINTENANCE AND REPAIR MANUAL).
