Operation
•
- The "open" and "close" functions are actuated by the valve control levers attached to the truck loading crane.
•
- The "open" and "close" functions are performed as long as the valve control levers are actuated
•
- The turning of the flange clamp with the turning motor must be carried out very carefully, otherwise the load may be
ejected
•
- The valve control lever equipped with a spring return must not be moved to its zero position with a jerk, as this will
build up pressure surges in the hydraulic circuit which may reduce the clamping force of the unit!
•
- The optimum holding or clamping force is obtained by holding the control lever in the closed position for two
seconds after closing the tongs
•
- In order to achieve an even load on the tool, it must always be placed in the middle of the grab goods (stone packs)
•
- When loading sensitive grab goods, the holding force of the device can be reduced by means of a pressure relief
valve
•
- Avoid jerky movements when the machine is loaded.
•
Carefully place the grab goods (building material packages) down again after transport
