Wind Turbine Installation Boom Crane
Our QLY2150 wind turbineinstallation boom crane adopts intelligent suspension tires which are fullyhydraulic and rotary. It also uses imported electro-hydraulic components, andthe lifter arm can realize straight, oblique and horizontal movement. Inaddition, the equipment can be conveniently transferred without having todismantle the arm and is applicable to only 5 meters wide dirt road. Dueto a maximum lifting height of 110m and maximum lifting capacity of 120t, thecrane is widely applicable to wind turbine installation with the power of 2.5MWor below.
The boom crane has an effective control system, which has the functions ofdisplay, commissioning, calibration, inspection, maintenance, etc. The displayis used to show the actual lifting weight, boom angle, working radius, liftingheight, speed, working hours, mileage, wind speed, engine temperature, fuelconsumption, cylinder temperature, and other parameters. Entering the password,the user has easy access to parameter setting. When a failure occurs, thedisplay can indicate relevant information and prompt operations or cut off thewindow for maintenance.
The crane control system makes use of imported RC controller and display,encoder and torque limiter, as well as closed-circuit surveillance unit. Ourlifting, slewing, luffing,servo, anti-backward, and auxiliary hydraulic systems adopts closed loop,featuring energy saving, high efficiency, good controllability, smooth start,stop and steering, non-impact, fast response operation, less heat, long servicelife. It also uses electro-hydraulic proportional control components tofacilitate accurate and intelligent control. While the electrical controlsystem uses CAN bus technology to for data transfer and improved reliability ofthe system.
The displays of the torque limiter, closed-circuit monitor and otherinstruments are all in the operator's direct field of vision. The torquelimiter display equipped in this boom crane is used for real-time detection ofcrane torque and other parameters, and the monitor display is used to show theoperating status, control parameter and alarm. There is an operating handle onthe left and right armrest, and the handle action can be switched by themonitor display button, with the separate action or allowable compound actiondisplayed in the form of text and graphics.
Our wind turbine installation boom crane is equipped with a variety of safetyprotection devices, such as the torque limiter, over-wind and over-dischargingprotection for the hook, mode switch, limit device and anti-overturn device forthe main boom, brake for the lifting mechanism, closed-circuit surveillancesystem, fault diagnosis system, black box, navigation light, anemometer,electronic level, lightning protection, boom tilt alarm, hook anti-loosingdevice, slewing and traveling alert, power limit load regulation and stallprotection, as well as monitoring instrument for the engine, etc.
