IN FOCUS / TUTT BRYANT
PERFORMANCE AND EFFICIENCY REDEFINED The New SCX2800A-3 crawler is the latest model from HSC Cranes to be released in the successful SCX-3 series. HSC CRANES, FORMERLY HITACHI Sumitomo Crane, is renowned worldwide for class-leading products of exceptional quality. Drawing from many decades of Japanese crawler crane development, HSC Cranes has recently been introducing to the market its new SCX-3 series. Following the local launches of the SCX1000A-3 (100t) and SCX1500A-3 (150t) crawler cranes, Tutt Bryant Equipment (the exclusive Australian distributor for HSC Cranes) is preparing for the introduction of the next significant SCX-3 model – the SCX2800A-3 (275t) crawler crane. Building on the highly popular SCX2800-2 crane, which is a mainstay on projects across Australia, the new SCX2800A-3 will likewise come in liftcrane or luffing/tower configurations and it headlines a number of advanced features to further increase performance and efficiency. With backward compatibility that allows interchangeability with Operators view of SCX 2800A-3.

components from the older model such as boom insert sections, owners will have much greater flexibility and economical reasons to upgrade to the new SCX2800A-3 while still utilising existing in-service crane components. Coming off a win at the Good Design Awards 2018 in Japan, the SCX2800A-3 boasts a familiar yet elegant design that will enable efficient transportation, assembly and disassembly, and much improved safety of the crane operator and those working in close proximity. Along with extra-wide windows, ergonomic designs such as a new large sliding door, a wide platform, and a comfortable and highly functional operator seat aim to reduce operator fatigue and increase functionality. For better visibility when moving loads at height, a tilt mechanism allows the cab to be angled by up to 18°. Optional handrails and walkways from the factory also ensure safety while working at

heights. Productivity is further enhanced by the fine speed control dials for hoisting, lowering, swinging and boom hoisting operations which are positioned beside the operator for ease of access, while a swing mode selector switch allows the choice between swing-free or swingbrake operation depending on work requirements and personal preferences. The all-new Load Moment Indicator (LMI) with data-logging capabilities records duty cycle and winch hours, as well as load moment and line pull. This should, in theory, increase the safe operational age of the machine from current methods employed in complying with the new Australian regulations. As a standard feature, remote sensing is installed in all machines to minimise downtime, ensure accurate maintenance and improve machine marketability. In addition to a powerful 13.5t rated line pull winch for steady operations, the SCX2800A-3 has an Eco-Winch mode which allows high line speeds under light loads without having to increase the engine speed (low rpm). Bringing lower fuel consumption and reduced noise, this is an eco-friendly feature that will save fuel costs and minimise environmental impacts. Productivity gains will also be achieved via a unique combined hydraulic circuit developed by HSC Cranes. By increasing and optimising the pump pressure through the use of a mixed circuit to control the hydraulic oil from two
