The BSP DX-RT range of hydraulic piling hammers have been developed to meet the needs of Railway Infrastructure projects. It’s design allows quick and simple mounting onto the stick of a wide range of small Road-Rail excavators (aprox. 30T class machines). The hammer mounts directly to the excavators bucket linkage and the attachment allows for fast erection from horizontal transport position to a vertical plumb working position. Further side plumbing adjustment is possible to give a hammer position ±5° of vertical to deal with the cant of rail lines. During piling the hammer is guided or crowded in the vertical position by the attachment mechanism.
As standard the hammer is fitted with a 800mm diameter drive cap which is well suited to the common application of driving 610mm (24”) dia steel tube piles used in the construction of rail electrification stanchions. It also allows for other common pile sizes such as 457mm (18”), 406mm (16”) and 305mm (12”) steel tubes. Other pile types and sizes can also be driven by fitting alternative drive cap options.
A typical high production piling train will use an excavator mounted side grip vibrator to place, pitch and part drive the pile. The powerful DX-RT pile driver with its rapid blow rate is then used to drive the pile to the desired level, quickly and efficiently.
The DX-RT range of piling equipment have the following important features:
| Performance Data | Ram Mass | Max Impact Energy | Blow Rate @ rated Energy | Operating Pressure | Hydraulic Flow Required |
|---|---|---|---|---|---|
| Model | kg | kNm | bpm | bar | L/min |
| DX-RT 20 | 1500 | 20 | 80 | 140 | 140 |
| DX-RT 25 | 2000 | 25 | 80 | 180 | 150 |
The SL range of piling hammers are designed for driving sheet piles and small bearing piles of concrete, steel or timber. The SL range is available with legs and inserts for use freely suspended or with backguides for operating from a piling mast. The hammers have the following important features:
- Total control of hammer stroke and blow rate
- Allows precise matching of energy to suit pile driving requirements
- Double acting cylinder produces high impact energy from a short stroke to give a high blow rate
- Slim design allows hammer to pass between upstanding piles
- Economical - Low Hydraulic power requirement
- Available with BSP Hydropacks for optimum hammer performance
- Hammer can be operated directly from Hydraulic crane or excavator bases
- Can drive piles with ultimate load bearing up to 1800 kN

The BSP range of large Piling Hammers shown here can be used freely suspended or configured with backguides for leader use. They include the following features:
- Cylinder and dropweight connection parts easily accessible.
- Digital readout of hammer performance in choice of units (i.e. Stroke or Energy)
- Square section giving a shorter overall height.
- Attachment points allowing vertical or raking piles to be driven.
- As shown piles up to 2m dia can be driven. With special attachments larger diameter’s can be accommodated.
