Sumitomo announces 175 tonne crawler

A 175 tonne capacity lattice boom crawler crane has been announced by Sumitomo Heavy Industries Construction Cranes Co Ltd (HSC).

The Japanese manufacturer has launched the SCX1800A-3 hydraulic crawler crane with a main boom up to 84 metres. Maximum main boom and crane jib combination is 75 + 31 metres. It is designed to offer “outstanding work capabilities within a refined compact body combined with superb transportation and assembly system.”

While the name suggests 180 tonnes capacity, this is available with the addition of special equipment. A heavy-duty top gives 180 tonnes at 4.1 metres radius with a 12 metre main boom. Standard is 160 tonnes at 4.5 metres radius.

An auxiliary sheave option offers greater lifting performance and caters to increasingly diverse customer requirements, the manufacturer said.

Power is from a Cummins QSB6.7 diesel engine, either to EU Stage Ⅳ / US Tier 4 final or EU Stage Ⅲ A / Tier 3 exhaust emission regulations. An ECO winch and auto idle stop function are designed to allow operations using less fuel. Unnecessary fuel consumption has been reduced so that there is less impact on the environment, Sumitomo said.

Easy transport and assembly were primary considerations. Total weight for transport, including lower boom, winch rope and mast is given as 40.8 tonnes. The main crane body weighs 27.6 tonnes. All parts remain within 3.2 metres for transport. A new counterweight design sees the same slabs used for left and right, including the base, to help speed up and simplify assembly.
