Excavation pit support

Duty cycle cranes with diaphragm wall grabs or hydro cutters are the most important equipment for foundation work and for sealing building ground and excavation pits. SENNEBOGEN duty cycle cranes are used as carrier equipment for the diaphragm wall grab. The flexible and all-terrain telescopic crawler cranes are excellent as feeders for the machines working the excavation and producing diaphragm walls.

The diaphragm wall technique can be used to great depths. The comprehensive concept of the SENNEBOGEN duty cycle crane is convincing due to:

• sensitive control, sensitive braking systems and excellent winch traction at high cable speeds
• hydraulic and electronic winch synchronization
• special equipment such as depth measuring device
