Topkit Hammered Self-Erecting Tower Crane QTZ250(TC7032) 12T
>> ABOUT US <<
We are committed to the professional manufacturing of tower cranes and construction hoists. Our firm has manufactured and sold approximately 50 thousand sets of tower cranes and construction lifts. We have been exported to over 50 countries and regions. Our product portfolio comprises 4 main series and over 60 types of products, such as high-top tower cranes, flat-top tower cranes, luffing jib tower cranes and construction hoists. All products come with ISO, CE, and other certificates.
We provide full ranges of tower cranes with hoist weight from 2t to 50t.
Minglong Tower Crane products can be used independently or with attachment anchor, and the length and height of the boom can be adjusted according to construction requirements. The products feature high working speed, good adjustment performance, and high efficiency. The hoist structure adopts 3-speed electric motor and single speed ratio redactor which can achieve heavy load at low speed and light load at high speed.
Characteristics of QTZ250(TC7032) Tower Crane
1) The Crane adopts standard section hydraulic lifting and connecting, can decide the crane height according to the actual height of the building, and at the same time, the lifting capacity will not be affected.
2) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerators are applied in the lifting structure, which enables heavy load low speed and light load high speed.
3) The machine has complete set of safety devices, which can guarantee the safe and high efficient operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter and circumgyraing limiter, etc.
Good quality, competitive prices and excellent after-sale service.
Product advantage:
The Steel Structure with Long Lifespan and High Safety The flat-top tower crane is designed without any pull rod so as to reduce the height of the tower top and meet the requirements on different work sites. Especially suitable for disassembling and assembling on restricted construction sites or during the multi-tower cross operation The height difference between tower bodies can be reduced to save much space and cost.

Hoisting Mechanism
Speed regulation mode: variable frequency motor speed regulation, The reducer adopts F610 type, and the improvement effect is obvious; Brake: the brake is Jiaozuo brand. Wheels are made of cast steel. Dynamic balance test. Reliable, safe and durable braking; Steel wire rope: long service life, high safety and low maintenance cost.
Trolleying Mechanism
Variable frequency speed regulation, stable and reliable starting and braking Low maintenance rate gear reducer The operation efficiency is 10% higher than that of ordinary trolleybus.
Hook
Increase the weight of the hook, effectively improve the rope lining effect during lifting; adopt new structure to prevent the hook pulley from falling off, completely solve the problem of rope falling off. A movable joint is added between the hook plate and the cross beam to facilitate the hook operation.
Trolley
A semi-circular protective ring is added to the lower part of the sports car pulley, which fundamentally solve the wire rope groove failure caused by high-speed lifting during the turning process.
Mast section
Overall processing after welding, high connection accuracy, more effortless disassembly; Each section is equipped with a rest platform, which is convenient for disassembling the pins, and the inclined aluminum alloy ladder makes climbing safer and labor-saving;
Electric Box
The electrical control system design uses the European advanced frequency conversion + PLC + heavy-duty plug-in electrical control box design system, which is simple, easy to install and disassemble improve work efficiency.
Cabin
Convenient installation, low operation cost and long service life of products.
Telescopic
The frame, lifting cylinder and lifting beam have been assembled before leaving the factory, which can be directly hoisted on site
Hydraulic Jacking Mechanism
The mechanism and the jacking system have been refueled, the wire rope has been wound, and the tower crane is ready for use; saving on-site installation costs.
Safety protection device
The weight limiter and torque limiter adopt a tension ring structure. Lifting, slewing, and trolleying limiter adopts cast aluminum casing with long service life, and adopts products from Guiyang Electric Control Factory.
