SUNHUNK Knuckle Boom Crane
1、The key structural components are welded with Q690 high-strength steel plate, which has high strength and light weight.
2、The slewing reducer has a rated torque of 4400 N.m, which is the highest torque among its peers, providing stronger operational capability.
3、The boom is an enhanced hexagon structure with stable telescoping and a lifting capacity 20% stronger than conventional hexagon structures.
4、The boom telescoping mechanism is imported with a three-stage cylinder and rigging telescoping, sequential extension, and the first two telescoping arms are driven by independent cylinders. The medium and short arms have strong load-bearing telescoping capabilities.
5、The maximum operating range is 18.7 meters, which is the largest in the industry for the same tonnage and has strong cross-obstacle capabilities.
