Lifting and lowering device for e.g. pile, has outer casing held against inner casing by vibration damping device and provided with surfaces for centering and vertically positioning pile

摘要

The inner and outer casings are held together by a vibration damping device. The outer casing has a surface with a centering device for lowering the object, as well as another surface for positioning the object in the vertical direction. The device is designed to be temporarily fixed to a tool fastener on a vehicle such as an excavator and includes at least one hydraulic gripper and at least one hydraulic vibration damping device.
