Both the chord and pull rod of the jib from Dahan Construction Machinery are made from Q345B manganese steel. The diagonal web member is a high-toughness seamless steel pipe. Adopting twice tempering process and stamping process to eliminate cracks can greatly improve the safety and reliability of jib bearing.
The inverter, contactor, circuit breaker and other main electrical components are derived from Schneider Electric for increased reliability and durability.
The steel wire rope is designed with an anti-skipping device. The trolley is designed with an anti-slip device, an anti-drop device and an anti-shedding and tipping device.
A combined length of 60m, 55m, 50m, 45m, 40m and others can be achieved by changing the number of counterweight and adjusting the jib, which can meet your requirements on different construction sites.
