Restricted working room piling projects are the main target of a new piling rig created by a collaboration between manufacturer BSP International Foundations and rental specialist Colets Piling.
Following discussions with customer, Colets recognised the need for a piling rig to top drive steel or concrete foundation piles for small to medium-sized housing projects. The main criteria for the new rig was ease of transportation without the need for movement orders and to create a rig that would cut the costs of piling mats, as well as creating a rig that was fast to set up and efficient to use.
“This collaboration between our two companies has resulted in the JX model, the first purpose-built piling rig of its type in the UK, which was built and ready for work in six months,” said Colets sales manager John Walter.
BSP senior sales manager Ray Ransome added: “During the building process we encountered a few technical problems but these were resolved quickly with minimum production delay. Now that the machine is working in the piling field, we are extremely confident it will prove to be a valuable addition to the Colets Piling fleet and ultimately provide many years of productive service.”
The machine is based on a JCB JS excavator, which was selected by Colets as it already has a number of the machines in fleet with rotary drilling systems. The collaboration with BSP has led to the machine being fitted with 2t dropweight hammer on a 13m mast to allow installation of 8m long piles.
With a working radius of 3.1m, the mast can be placed in any position around the base of the machine while the five degrees of mast rotation, left or right, helps keep the mast vertical when working on uneven ground. The rig can self-erect its mast without the aid of additional plant. It also has two dedicated lift winches, one to raise the hammer and the other to lift a pile with a maximum weight of 1.5t. Hydraulic arms retain the bottom of the pile to guide it in place once positioned at any point around the machine. There is also the option of a telescopic foot fitted to the bottom of the mast to guide the pile.
One of the first projects involving the JS Rig was the driving of concrete piles on the third phase of a new housing development being built by Bovis Homes in Congleton, Cheshire. The new rig was hired to Tritech Piling and Foundations by Colets Piling to drive 200mm square concrete piles between 6m and 7m in depth on the site. All the piles were driven to a set with the DX hammer performing a 300mm long stroke.
