Kobelco Cranes has responded to demand from customers for equipment to meet ever more challenging foundation projects around the world with the launch of the new 120t BMS1200HD heavy duct foundation crawler crane with lattice boom.
The company says the machine is the successor to the BM1200, which was first introduced in 1991. The crawler crane can also be used for conventional lifting duties and also barge-mounted for either foundation or lifting operations.
The new model is equipped with high-performance winches that offer up to 314kN of line pull on the main winch and an auxiliary winch with 36mm diameter rope. The third winch has a rated line pull of 132kN. Kobelco says the line speed offered by the winching system on the first layer is twice as fast as those offered by its competitors.
According to Kobelco, the crane has a high spooling capacity that makes deep excavation possible while working from the first layer, which has the advantage of increasing the lifespan of the wire rope to reduce running costs and improving on site efficiency.
The design of the crane has focused on ensuring it can work with a number of different attachments, including clamshell bucket, diaphragm wall-bucket, hammer grab bucket, oscillator casing drive and rotator casing drive up to 3m in diameter, fly-drilling from 1.5m up to 5.5m in diameter and vibrohammer by centrifugal force and from 700 up to 1624kN.
Kobelco has said that it is aware that the 120t weight of the crane presents some issues for transport, so has worked to minimise the weight of the base machine to 46.9t.
