Vibratory Hammer for driving sheet piles

Swinging Leads

These leads are attached to the crane at the top by the main cable.
They have a gate at the bottom which holds the leads around the pile and will sometimes have spikes on the bottom which are stuck into the ground or template to assist in aligning the hammer.

Pile Cap or Helmet

This is the section of the pile driving system which rests between the hammer and the pile.
For concrete piles, it contains the striker plate or drive cap, a hammer cushion, and the pile cushion

Hammer Cushions

Hammer cushions are constructed of man-made materials that are heat resistant, durable and absorb a certain amount of shock.
Common types of materials are aluminum, micarta and polymer which are in the form of disks

Pile Cushions

Pile cushions are placed between the pile top and the pile cap on concrete piles.
Pile cushions are not used on steel piles or timber piles.

Semi-fixed Leads

This type of lead has a pivot or sliding connection to the crane at either the top or bottom of the leads. Normally the connection is at the top of the leads

Leader

The Leader consisting of a pair of steel frame is fabricated with steel structure to mount the Hammer on it and it used in conjunction with Cranes, Pile Drivers or mechanical Excavators. The Leaders to mount BRUCE Hammer can be utilized as a Fixed Type and U-Type that are the leading Leader type allowing it access to a difficult area and relatively easy to set up for whole operation.

Long Pile Skirt for Crane Suspended Pile Driving

This type of Hammer operation has no Leader is used and normally is accomplished its sheet pile driving work on offshore project. The Hammer requires a lifting wire rope to lift it directly by a Crane due to the limitation of taking Cranes position when it is being apart from the land. The Long Pile Skirt is generally used for marine and offshore pile driving job.

Suspended Leader for Crane Suspended Pile Driving

Hanging leader consists of a pair of channels similar to the leader of a pile frame suspended from the jib of crane and positioned with the aid of adjustable strut. Hanging leaders are used in conjunction with cranes.
