Diesel engine drilling rig LRB 19

electricmechanicalrotary

Overview
The LRB 19 is a specialized leader rig for deep foundations, combining piling and multi-method drilling capabilities. It supports Kelly drilling, continuous flight auger (CFA), full displacement, double rotary and soil mixing. The hydraulic quick-connection docking station allows fast attachment changes with automatic hydraulic, mechanical and electrical coupling. The rig features a 19 m carriage travel and a 450 kW engine for heavy-duty foundation applications.

Key features

• Hydraulic quick-change docking station for rapid, tool-free attachment swaps; automatic coupling of hydraulic, mechanical and electrical connections
• Improved hose routing with hose sledge to reduce interference during operation
• Compact transport design allowing transport as one unit (even with vibrator mounted on the leader)
• Working-area restriction: continuous monitoring of rotation range, working radius and machine height with automatic stop in restricted zones
• Optimally arranged LED work lights for improved visibility in the work area
• Obstacle recognition for early detection of subsurface obstacles to protect attachment and base machine

Product highlights

• Operating weight: 53.0 t (one configuration) or 48.2 - 50.7 t (other configurations)
• Max. torque: 180 kNm
• Max. winch line pull: 110 kN
• Max. crowd force: 250 kN
• Engine power: 450 kW
• Pile driving with slim vibrator — max. pile length: 18.0 m

Applications

• Kelly drilling for deep bored piles
• Continuous flight auger (CFA) drilling
• Full displacement (full-displacement) drilling
• Double rotary drilling
• Soil mixing and ground improvement
• Pile driving with vibrator and hydraulic hammer
