Hydraulic pile-driving hammer DX series

The DX range of hydraulic piling hammers are designed for small bearing piles of steel, timber, concrete and many sheet piles. The DX hammer is available with back guides for operating from a piling mast or a slider for operating from an excavator. DX Hammer Main Image The DX hammer can be mounted on road, rail or tracked excavators with an operating weight of around 32t or greater. Applications include railway equipment installation and maintenance. Specifically developed to drive steel piles to support electrification stanchions, gantries and other railway projects requiring foundation piling. When mounted to the excavator’s bucket linkage, the hammer can be quickly erected from a horizontal transport position to a vertical position. Side tilt adjustment of five degrees left and right allows it to cope with the cant of the rail lines. During piling the hammer is automatically guided or crowded in the vertical plane.

Maximum impact energy is 20kNm, 25kNm and 30kNm respectively while blow rate at rated energy for or models is approximately 60 blows per minute. DX hammers can also be used to drive sheet piles, small bearing piles, tubular steel piles, timber or concrete piles with ultimate load bearing up to 1800kN. They can be operated directly from a suitable hydraulic excavator. A feature of the new hammers is an innovative BSP double-acting cylinder, whereby the ram is accelerated on its downward path to achieve higher impact energy.
