Sumitomo Heavy Industries Construction Cranes Co. (HSC) has announced the launch of two new crawler cranes: the SCX1000HD-3, with a maximum lifting capacity of 100 tonnes, and the SCX1800A-3, with a maximum lifting capacity of 175 tonnes.

These follow the launch of the SCX800A-3 and SCX1000A-3 in December 2021.

SCX1000HD-3

The SCX1000HD-3, which succeeds HSC’s SCX900HD-2 model, has been developed based on the concept of HSC’s SCX-3 series cranes and is designed for heavy-duty tasks, such as foundation and trenching work, the company said. The crane’s engine meets EU Stage ? A/ Tier 3 exhaust emission regulations.

It offers an extra ten tonnes of lifting performance compared to the SCX900HD-2 model it succeeds. A 13.5 tonne rated line pull winch with free-fall function is included as standard. This can be upgraded to a 15.5 tonne rated line pull winch (with free-fall function) if required.

In addition to the standard hydraulic oil cooler an optional additional hydraulic oil cooler, with improved heat balance performance, is also available. According to HSC improving heat balance means the crane is even more suitable for high-load work such as trenching for continuous diaphragm walls.

In order to enhance safety the crane comes with a swing restriction device and swing brake pedal. A warning alarm and an auto drum lock remain installed as standard. A large display panel includes all required information at a glance via an easy-to-view layout without disturbing operator’s forward visibility, said HSC. Catwalk and upper house handrails (folding type) are also installed as standard.

Increasing the crane’s environmental credentials, said HSC, is a highly efficient engine, an ECO winch, and an auto idle stop function so that operations can be performed using less fuel.

The crane’s operating condition can be monitored via remote sensors which are installed as standard. This helps with preventative maintenance, said HSC, which, in turn, contributes to improved operating efficiency.

SCX1800A-3

The SCX1800A-3 is powered with a new-generation Cummins B6.7 engine that meets EU Stage V emission standards for the highest level of clean running performance, together with an advanced control system (ECO winch mode, auto idle stop function) for energy-efficient operation.

Exhaust post-processing systems consist of a muffler filter and urea SCR. The preliminary stage muffler filter reduces particulate matter (PM), while the subsequent stage urea SCR cuts down on NOx emissions.

The SCX1800A-3 provides exceptional lifting capabilities with a compact body. Maximum main boom and crane jib combination is 75 m + 31 m, covering a wide working area to further streamline operations on worksites. A two-auxiliary sheave is also available to provide greater lifting performance, catering to increasingly diverse customer requirements. An optional 132 kN (13.5t) rated line pull winch is available.

SCX800A-3 and SCX1000A-3

These two cranes come hot on the heels of HSC’s launch of the SCX800A-3 and SCX1000A-3 crawler cranes, launched December 2021, with maximum lifting capacities of 80 tonnes and 100 tonnes respectively. Both these cranes are powered with a new-generation Cummins B6.7 engine that meets EU Stage V exhaust emission standards together with ECO winch mode and an auto idle stop function) for energy-efficient operation.

Like the SCX1800A-3, both cranes have an exhaust post-processing systems comprising a muffler filter and urea SCR to reduce PM and NOx emissions.

According to HSC, both these new-generation crawler cranes provide outstanding environmental capabilities while retaining their high level of work capabilities and ease of transportation and disassembly.
