NBR adds platform model to crawler transporter range

Heavy lift transporter specialist NBR Offshore Logistics has a new crawler mounted 350 tonne capacity model. The C400PL is a heavy transport unit with a flat load platform on top of a pair of crawler tracks. They can be used singly, coupled in pairs or up to 20 units can be synchronised under large loads. It is designed as an alternative to heavy lift wheeled transporters, for example, self propelled modular transporter (SPMT).

Capacity of the new model is 350 tonnes per unit and its load platform is 6 x 5 metres. A multiple angle tilt function on the load platform allows it to remain flat while the crawler unit follows undulations in the ground. To do this it has an automatic computerised three point levelling system. Transport speed under full load is 0.5 km/h, the manufacturer said. Steering is computerised and there is a data logger with remote transmission.

Power is from a 306 kW power pack unit with MTU diesel engine. The hydrostatic track drive helps allow it to cope with a 21.4 % maximum gradient. Overall dimensions are 6.5 m long by 5 m wide. It stands 1.4 metres tall to the top of the load platform and the height to the top of the crawler tracks is 1,286 mm. The stroke of the lifting cylinders allows a variation from 300 to 500 mm. Each unit weighs 41.5 tonnes. For easier transport on flat racks or in open top containers they can be built as divisible units.

Other models offered by NBR is a range that includes the C250, C250B, C250BE, C350 and C520. Instead of a flat load platform these units have a vertical levelling cylinder with a ball type top mounting. In the model numbers the “B” designation is for wider crawler tracks and the “E” denotes longer track frames.
