Sennebogen has announced a new 50 tonne lattice crawler crane, the 1100 E, the smallest model in its current range.

Boom lengths range from 10.3 to 52.3 metres and as with other Sennebogen cranes in the range the 1100 switches into a safe mode when the capacity on the hook exceeds 90 percent of the load chart and can also lift on slopes up to three degrees. Overall weight of the basic machine is just 30 tonnes and transport width three metres.

Power comes from a Cummins Tier Vlf diesel coupled to multi-circuit hydraulic system to ensure simultaneous crane operations. A Tier llla option is available for markets where permitted. The main hoist has a maximum speed of 125 metres a minute and is driven by a high pressure adjustable hydraulic motor for maximum efficiency.

The cab has been designed for maximum visibility and comfort and includes climate control and a heated air sprung seat.
