Description:
CFM hydraulic pile hammer is the result of the hydraulic hammer designing, using and manufacturing experience for more than ten years. It is with simple design and fine design, and the striking energy can be adjustable according to foundation condition and pile depth. Pile in the same foundation condition can be program group pile copied by the trailing pile.

Besides that, the cap can be designed according to the customer requirement, to be suitable for each kinds and specifications of concrete pile, steel tube pile and steel plate pile. CFM can supply each kinds of hydraulic pile hammer, from 60kJ to infinity. Simple reliable design, find manufacturing and fast service can make sure the pile hammer give full play.

The off shore pile hammer is mainly for sea industry off shore foundation construction. Its working area can be big sea industry foundation construction, such as oil and gas platform on sea, big bridge, tube installation, deep water structure and wind power on sea and so on. It is mainly for each kinds and specifications steel pile and prefabricated pile.

 Comparison to onshore hydraulic pile hammer:
Off shore hydraulic pile hammer uses pressurized fully closed hammer body design (patent) and submarine design to make sure the hydraulic driving system, control system, striking system can be work normally under deep water and to improve its transferring efficiency.

Special designing cap water level control system can make sure the pile hammer can work without touching water under deep water to improve its transferring efficiency much.

Special hammer cylinder pressure control system can realize automatic control the pressure in the close hammer body.

Forged and heated ram with long axle, and close automatic lubrication system can make sure hammer striking system work with high reliability.

Special antiseptic and ooze proof designing can make sure hammer work for long time.

This off shore pile hammer can be suitable for deep water working. Besides hammer body and hydraulic station, there will be with another auxiliary devices, such as winch for tube line and control maintenance station.

 The key technology and features:
1) Pressurize fully close hammer body (patent) make sure it can work with high reliability in very bad outside environment, especially the deep water working.
2) High integrated hydraulic driving system can make sure it work with high efficiency, energy saving, environment friendly and high reliability.
3) Automatic close technology for high pressure pipeline if pressure losing, is to avoid oil leakage during unusual knocking.
4) Oil drain technology for pipeline can make sure the oil drain out when shifting to other place, to avoid oil leakage and pollution.
5) Modern program control technology can realize normal and automatic control for striking energy and frequency in the same foundation condition. The striking energy can be willfully preset in the rated range.
6) Fine sensor technology, remote technology and man-machine interface can automatic monitor the pressure, temperature, position and its condition, to realize pile hammer numerical control and malfunction automatic diagnosing and displaying.
7) It can be guiding pile or free lifting pile.
