the H40 rig capable of piling up to 2,500mm diameter piles to 60m depth and the B135 compact selferecting rig, which can also sink casings with its rotary head.
Also on show will be the 30t C14 minipiling rig with a double rotary head which can handle casing up to 500mm in diameter and the new 7t C4 crawler drill.
The group acquired German manufacturer Hutte in April 2002.
The firm will be showing its HBR 609 rig, along with the new HBR 503 highly compact and lightweight 6t anchor drilling rig and the 10t anchor drill machine HBR 504 with double rotary head.
Caterpillar Caterpillar will introduce its new compact radius, utility and swing-boom excavators at Bauma.
The new C-Series excavators share many common features with other Caterpillar excavators in the 7t to 14t weight class but benefit from additional features enabling them to work on sites where space is limited, such as urban construction and road maintenance projects. These types of rigs are in high demand, the firm says, with about half of all machines sold in the fast expanding 7/8t class now compact radius models like the 308C CR.
Controls Construction material test equipment manufacturer Controls will show its full range of testing rigs at Bauma. Among them will be Sercomp 7, the digital console for controlling hydraulic frames and automatic testing programmes.
The system can store up to 500 tests, producing print outs and reports. It can control traditional and complex tests, such as cyclical testing to determine the elastic modulus of a specimen.
Dawson Bauma will see Dawson Construction Plant's 1,000t Universal Pile Extractor revealed for the first time, in response to the growing demand for removal of temporary steel sheet piles at the end of contracts.
While attaching a pile vibrator on the pile top to a crane is effective for this, forces generated are sometimes sufficient to snap the pile or to lose grip with catastrophic results.
Dawson says its extractor offers a viable alternative. It sits on the ground and grips the piles, pulling them out of the ground using two 500t hydraulic cylinders acting together. Practically any steel pile profile can be extracted, without vibration and with increased safety.
Also on show in Munich will be Dawson's quiet and vibration-free push-pull pile pressing system, designed for installing and removing sheet pile walls, box piles and for working close to buildings.
Finally, the firm will launch the HPH4500 hydraulic piling hammer, able to pitch and drive steel sheet piles, tubular piles, H-piles, timber or concrete piles.
EGT Italian drilling equipment manufacturer EGT will display all of its three main ranges, based around modular construction with interchangeable units.
