Product Description

Mingdao Crane Brand Topkit / Topless / Flat Top QTZ Tower Crane

Brief Introduction:This type tower crane has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work efficiency.

The QTZ series tower crane is mainly used for housing construction in the vertical and horizontal transportation of materials and the installation of building conponents.

It is widely used in infrastructure construction ,high-speed rail,oil fields,large ports,nuclear power,wind power and other construction fields.

According to the shape of the tower crane ,it can be divided into topkit type,topless type and luffing boom type.

According to the working efficiency ,it can be divided into ordinary type and frequency conversion type.Different models & Parameters:

Features:
1.Suitable for all kinds of construction project and can work under all kinds of work condition. 2.It has high working speed, good speed-adjusting performance, steady operation and high efficiency. 3.The crane has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment. 4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting structure, which enables heavy load low speed and light load high speed. 5.Planet gear decelerator is applied in the circumcise rating structure, together with moment-limiting hydraulic couple, which can realize high load capacity, steady starting and reliable operation.
Safety Decices:

Weight limiter	If the material is over the capacity, the crane will give a sharp warning for protection itself
Moment limiter	Real-time monitoring and detection of crane working conditions, with its own diagnostic function, rapid dangerous status alarm and safety control.
Height limiter	Control the lowest and highest extreme position of lifting hook
Slewing limit	Control the extreme turns number of turn left and right.
Emergency brake	If the operation staff encounter some emergency situation, we could start the emergency brake system to protection the related treasure.

Control Mechanism:Hoisting mechanism is driven by three-speed electromotor with high working speed and good speed-adjusting capability and high efficiency; Derrick mechanism using worm-wheel reducer can meet operating needs. Slewing mechanism that is driven by two-speed electromotor; Make operation more stable and reliable.Advantages:1.Robot automatic welding system;2.Automatic impeller blasting and spraying assembly line;3.CNC plasma cutting machine;4.Precision machine tools;5. France Schneider contactor;6.Jiangte motor;7.Equipped with complete set of safety devices
