Stronger long boom
The use of upgraded high-tensile steel (690N/mm2) enables the boom strength to be enhanced by 15% compared with the conventional one. To reduce a shock when telescoping the boom, a valve is newly fitted with inside the telescoping circuit.
New type of the outrigger
The employment of a new parabox-type outrigger enables the outrigger to secure a maximum extension width of 4.8 meters which enhances crane performance substantially in a stability zone.
Centralised control panels
A horn switch and displayed in panels together with an empty chassis rated lifting capacities chart - one on each side of the crane.
Excellent function at the boom head (except ZR566)
A wider space secured between sheaves at the boom head prevents the wire rope frombeing twisted, and this helpes prolong the life of the wire rope.
