More depth with the drilling rig LB 45.1

The new LB 45.1 is designed for all common piling methods in deep foundation work. These include Kelly drilling, continuous flight auger drilling or double rotary drilling. For applications with full or partial displacement equipment, the device can reach a drilling depth of 37 metres thanks to the optional lattice boom extension. This corresponds to an increase of six metres. The advantage of this is that customers can use a compact device for greater depths, even for geologically challenging drillings, and are therefore very flexible on the jobsite. The lattice boom extension can be easily retrofitted to any LB 45.1. The model has been equipped with a new powerful 450 kW diesel engine and impresses with a torque of 450 kNm. The maximum winch line pull is 420 kN and the maximum pull force is 1000 kN. At Bauma, the exhibit shines in a new design and is presented with full displacement equipment.

Automation, efficiency and comfort

The working processes of the LB 45.1 can be automated using a variety of innovative assistance systems, thereby increasing efficiency as certain work steps are completely taken over by the machine's control system. Examples include the drilling assistant to automate the concreting process during continuous flight auger drilling, slack rope monitoring to prevent undesired loosening of the rope with the help of the winch control and automatic leader alignment to automatically align the leader to the previously set inclination angle.

The new overload protection of the Kelly winch ensures that the locked Kelly bar automatically stops the crowd winch if the maximum permissible load of the Kelly winch is exceeded. The rope length measurement of the auxiliary winch measures the length of the unwound rope, which is very helpful when inserting reinforcement cages, for example. Locking of the Kelly bar’s telescopic sections is made significantly easier due to the Kelly visualisation system in the LB 45.1. Thanks to the real time display of the Kelly bar’s locking recesses on the cabin monitor, the operator is permanently informed about the actual distance to the next locking recess. Colour indications inform when the bar can be locked. Furthermore, false positioning of the Kelly bar during the shake-off process is indicated through a warning signal.

In the new cabin, the focus lies on ergonomics and operating comfort. This is accomplished with an orthopaedic driver’s seat, individually adjustable monitors and a cool box for food. The new refuelling position of the machine, which is easily accessible from the crawlers, also increases convenience on the jobsite.
