VIBRATORY HAMMER HAVING SEQUENTIALLY CONTROLLABLE SLIDING GRIPPER
Disclosed is a vibratory hammer used to drive a pile in a foundation work of a construction site. A pair of main grip portions of a main gripper capable of gripping a pile are mounted on a pair of sliding arms capable of linear reciprocation. While the main grip portions and the sliding arms make linear reciprocation, a gap between the main grip portions is adjusted depending on a size and a shape of the pile (primary sliding operation). While a jaw pad of the main grip portion that substantially grips the pile also makes linear reciprocation by virtue of self-power of the main grip portion, the pile is gripped (secondary sliding operation). The primary and secondary sliding operations are sequentially performed.
