Abstract (en)
[origin: WO0031364A1] The driver comprises a guide (12) having a hammer (18) thereon and an actuator (62) for urging the hammer along the guide (18) to a position where it can apply a driving force to a post or other member. A valve (68) is provided for reversing the operation of the actuator (62) after the driving force has been applied so as to urge the hammer (18) back along the guide. A cap is also provided through which striking load is applied by the hammer (18). The guide (12) is mounted on a mast (10) which can be raised and lowered by means of a further actuator. The actuator may be arranged to apply a load to the cap during the operation of the hammer. The actuator (62) drives the hammer (18) through an arm (48) and a resilient device (56).
