Mainly applied for quick repair and majintenance of the wind power electric devices. The crane adopts se1f-climbing type hydraulic hoist ing systemto replace the past expensive wind power maintenance device-large-scale crawler crane.Its se1f-climbing hydraulic platformis connected to the tower cylinder harmlessly by multi-touch, which matched with safety monitoring protecting system, could realize the interlock between the hydraulic and mechanicalmechanism. The domest ic advanced leve1 successfully.
This crane is consists of four major components: adaptive clamping system, high folding winch lifting system, hydraulic system and electrical control system.Automatic climbing, electric hydraulic drive, flex ib1e operat ion, quick maintenance.and reliable performance.
Adaptive climbing system is connected by four sets arms device made by special polymer materials with the wind tower, which increases friction at the same time reduces damage to the tower. During working, 4 holding arm legs will work into 2 groups and are driven by telescopic cylinders to achieve climbing.
High folding winch lifting system consists of winches, slewing, and luffing telescopic devices, achieving vertical and horizontal movement. The rotary, telescopic luffing make crane in full range of work but also make the whole easy to transport.
Two variable hydraulic proportional control systems not only improve the security of the entire hydraulic system, but also reduces the energy consumption of equipment and safety problems, to provide protection for reliable operation of the entire device. Currently, Weihua self-climbing crane for wind turbine maintenance have been declared 4 national utility model patents and 1 national invention.
