Lightweight, Solid Upper Frame The upper frame has been newly designed to increase sectional strength and optimise the frame’s stress capacity. This enhances rigidity and contributes to the crane’s exceptional lifting capacity. High-strength Lattice Boom, Ready for Hard Work Large-diameter main pipe strengthens the boom to significantly boost  lifting capabilities. Double Motors for Smooth Travel The crawler has double motors, one in front and one in the rear,  delivering steady, powerful traction for  smooth on-site travel.  Smooth Hoisting Increases  Work Efficiency Hoisting speed increases by approximately 30% ensuring faster,  more efficient work. Wide, Large-capacity Winches for Smooth High-rise Work The wide hoist winches provide an  impressive spooling capacity of 1,080m*  of 28mm hoist rope. Their large  capacity and large diameter prevent  uneven spooling and wear while  ensuring smooth operation during  high-rise work with a long boom  combination.  *SL6000S figure. Powerful Line Pull Winch Makes Tough Jobs Easy With the efficient combination of a high-output engine and high performance hydraulic motors, the winches deliver plenty of line pull for single-line work. There’s also ample capacity to get even the heaviest loads off the ground.
