BSP 357-9
Hydraulic Piling Hammer
Introduction
The BSP range of hydraulic hammers has been developed since the mid 1970's and aims to bring the most recent technology to pile driving techniques. With more than 70 years experience, BSP have maintained long contact with pile driving contractors and with their help have built a hammer which can meet most driving conditions likely to be encountered anywhere in the world.
As there is no exhaust these hammers can be used within pile tubes or noise reducing sleeves, thereby making pile driving in an urban environment more acceptable without reducing efficiency.
Design concept
The hammer system has been designed with flexibility of use as one of the major objectives. The modular form and interchangeability of parts allows a wide range of piling techniques to be undertaken with one complete hammer system. The hammer can be tailored to suit any customer and/or piling requirements without radical changes in design and be environmentally acceptable in the modern world.
It can be used in a piling lead, pile frame or freely suspended. The design incorporates either solid or segmental ram weights, and with its variable stroke control gives a wide pile driving energy range.
With extra sealing and modification of controls the hammer can also be used under water to depths exceeding 100 metres.
Versatility
A major benefit of the BSP hydraulic hammer is its versatility and it is suitable for driving all types of steel sheet piles, pre-cast reinforced concrete, pre-pressed concrete and timber. It is adaptable to a wide range of energy and pile requirements and the modular construction with interchangeable ram weights etc, leads to a more economical total hammer package.
Modifications for large diameter tubes
Watson & Hillhouse have increased further the versatility of the 357-9 hammer by building a special wide leg assembly to enable 1.2m O/D tubular piles to be driven. Further modifications to the hammer by ourselves also means that it can be fitted inside a Delmag MA270 leader to drive upto 2.0m O/D tubular piles
