Piling on the power

Liebherr's new LB Series rotary drilling rigs are designed for operations using Kelly equipment, continuous flight augers and double rotary heads. These can be used in an array of ground stabilisation applications for construction projects and complement the firm's proven LRB range of combined piling and drilling machines. There are four models in the new LB range, with operating weights from 68.4-113.5tonnes and these are capable of drilling diameters from 1.2-2.5m and to depths from 35-70m using Kelly equ

718 Liebherr's new LB Series rotary drilling rigs are designed for operations using Kelly equipment, continuous flight augers and double rotary heads. These can be used in an array of ground stabilisation applications for construction projects and complement the firm's proven LRB range of combined piling and drilling machines. There are four models in the new LB range, with operating weights from 68.4-113.5tonnes and these are capable of drilling diameters from 1.2-2.5m and to depths from 35-70m using Kelly equipment. The powerful LB28 offers a maximum torque of 280 kNm and features a rope descent system with a 40tonne retraction force. The machines are said to be stable in operation and can be transported in a single unit. Where transport restrictions apply, the leader features a quick-assembly system to minimise set-up time on-site.

    To meet a need to carry out complex modern bridge designs, the Terex Bid-Well 3600 paver is available with truss transition inserts, increasing maximum paving width from 27.4-33.5m. The inserts adjust truss depth from 914-1219mm toward the paver’s centre, reducing frame deflection and this is said to increase surface profile smoothness. Offering paving widths from 4.6-33.5m with optional transition inserts, the 3600 gives companies more versatility for paving a wide variety of bridge designs, including mult

    Mike Woof reports on equipment developments in the demolition sector. The hydraulic hammer is a tough tool used in a wide array of demolition jobs. Highly versatile, the breaker has evolved from a simple design based on rockdrilling equipment into a sophisticated and reliable piece of machinery. German firm Krupp and French company Montabert were pioneers of the hydraulic breaker, being followed into the market by a growing array of other manufacturers. Early breakers had the unfortunate habit of tearing th
