New Hydraulic System A choice of two hydraulic modes optimizes hydraulic performance in all working configurations by preventing interference during simultaneous operations. In Mode 1, designed for crane operations, one pump drives the main hoist and auxiliary hoist winches and the other pump hoists the boom winch. In Mode 2, designed for tower specifications, one pump drives the main hoist winch and the second Mode 1 (Crane operation) Boom pump drives the auxiliary Aux. hoist Main hoist (Tower jib hoist) hoist winch Engine (for hoisting Pump Pump the tower jib) and hoists the Mode 2 (Tower...

No compromise in KOBELCO’s safety policy Reliable Safety Features Two-Stage System to Prevent Boom and Jib Over-Hoists With primary and secondary over-hoist prevention devices, this new safety system can prevent boom overhoist at two stages. The primary stop function is activated when the boom or tower approaches the critical angle-toground during hoisting. This new system monitors the angle-to-ground of the boom, tower or jib with a sensor, and swiftly alerts the operator of danger. For the tower, the angle-to-machine is also monitored at this stage. The secondary stop function uses a...

Efficient Transportability and Assembly The base machine, with boom base attached, has a transport weight of less than 50 tons. Horizontally stacked counterweights are easy to assemble/disassemble and transport. Boom can be easily assembled with cantilever style up to a length of 36.6m. Intermediate support cables are not reguired for boom self-erection. Double-tapered pins for boom base enable the boom to be safely assembled/disassembled from the outside. The upper spreader storage guides make it easy to connect guy cables. Gantry raising/lowering cylinder, as standard equipment, makes...

For better man-machine communication Multi-Function LMI Display Multi-Function LMI Display The newly designed load moment indicator (LMI) system features a large, easy-to-read LCD display. The rated load, actual load, load ratio, and other information are displayed in large characters. Warnings and other items are displayed in color, and text messages and alarms alert the operator to prevent dangerous conditions from developing. Other information can also be displayed, including a rated load chart and rated load curve, in addition to a function that regulates the working range. The...
