New and updated HSC crawler cranes
By Alex Dahm07 January 2022
Sumitomo Heavy Industries Construction Cranes Co., Ltd. (HSC) has four new and updated crawlers in 80, 100 and 180 tonne capacities.
A new heavy duty crawler joins three updated models introduced in December and January by the Japanese manufacturer.
The new 100 tonne capacity HD model replaces the SCX900HD-2. Capacity is 10 tonnes more than the outgoing 2-series model. The new SCX1000HD-3 is developed for heavy-duty work from the company’s SCX-3 series crawlers. Boom length is from 12 to 60 metres.
Applications include trenching for diaphragm walls and constructing foundations. As standard fitment it has a 13.5 tonne-rated line pull winch with free-fall. A 15.5 tonne version is on the options list. Maximum line speed on the main drums is 110 metres a minute.
Also standard is an oil cooler. Adding the optional second cooler allows the machine to do high-load trenching for continuous diaphragm walls, HSC said.
Other standard features include swing restriction, auto drum lock, catwalks and handrails on the upper works.
The 280 kW Cummins QSL9 engine meets EU Stage Ⅲ A or Tier 3 exhaust emission regulations. It has auto idle stop to save fuel and there is an ECO winch mode.
The three updated, SCX-3 series, models all have EU Stage Ⅴ compliant Cummins engines. They are the SCX800A-3, SCX1000A-3 and the SCX1800A-3, in 80, 100 and 180 tonne capacities, respectively. Power for all three is from the new-generation 209 kW Cummins B6.7 diesel engine. They have the control system with ECO winch mode and auto idle stop for energy-efficiency. Two-stage exhaust aftertreatment includes a particulate filter and urea selective catalytic reduction (SCR).
The SCX800A-3 can have up to 54.5 metres of boom or a maximum boom and jib combination of 45.5+18 metres. For the 100 tonne SCX1000A-3 it is 60 metres of boom or a maximum boom and jib combination of 51+28 metres.
Maximum main boom and jib combination on the SCX1800A-3 Stage V is 75+31 metres, allowing it to cover a wide working area to further streamline operations on worksites, HSC said. Options include the two-auxiliary sheave to increase lifting performance and a 132 kN (13.5 tonne) rated line pull winch. The SCX1800A-3 was launched in mid-2020 with EU Stage Ⅲ A or Tier 3 engine.
