Zhejiang Construction Engineering Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of boom 50m topkit tower crane in China. With abundant experience, we warmly welcome you to buy advanced boom 50m topkit tower crane made in China here from our factory. Good service and quality products are available.

QTZ63 (ZJ5012) Topkit tower crane, load moment is 63t.m, max capacity is 6t, jib length is 50m, free-standing height is 31m, attachment height reach to 142m. This tower crane is commonly used in the cities, rising hundreds of metres in the air to construct huge skyscrapers.

Boom 50m Topkit Tower Crane adopts a variety of advanced technologies to ensure stable operation and reliable management. The tower crane is equipped with a variety of devices, such as hydraulic self-propelled devices, variable frequency slewing devices, and a series of reliable safety devices, such as lifting height limiters, slewing range limiters, and multi-function limiters. Therefore, this 5012 construction tower crane makes it easy for this heavy lifting equipment to more accurately control the lifting capacity, load moment, and trolley travel range. In addition, various electrical safety devices such as anemometers and obstruction lights can effectively prevent the trolley axle and wire rope from breaking.

Raw materials are the basis of products and the first step to ensure quality. Our cranes directly purchase steel in bulk from large steel mills such as Baosteel and Wuhan Iron and Steel, which improves product safety.

• Lifting mechanism

The brake wheel is made of steel material, surface hardened, and cylindrically ground, and the runout is strictly controlled. At the same time, dynamic balance tests are conducted, and each lifting mechanism undergoes no-load, static load, and dynamic load tests to ensure that the brakes are safe, durable, and reliable.

• Slewing mechanism

The rotating motor adopts a winding motor, hydraulic transmission, and stable rotation.

• Control device

The cab adopts a humanized design, which is convenient and comfortable, making driving easy and safe.

• Protective device

Complete protection devices can effectively improve safety.

Weight: the weight of the underground section without load and ballast with the longest jib and maximum free-standing height.

The machine is composed of steel structure, driving mechanism, hydraulic lifting, electrical control, and safety protection devices.

The steel structure mainly includes tower body, boom, climbing frame, tower top, balance arm, upper and lower supports, boom pull rods, balance arm pull rods, and attachment devices.

 

The tower body is divided into two types according to different standard section heights. One standard section has a height of 3 meters, and the other standard section has a height of 2.8 meters, equipped with different racks. The basic section is divided into two types according to the different forms of the foundation. When users choose a flange foundation, the bottom of the basic section is configured in the form of a flange plate; When selecting the support form, cross-shaped frame, or underground section, the bottom of the foundation section should be configured as a connecting sleeve form.

The climbing frame mainly consists of a frame, a platform, a hydraulic lifting device, and a standard section introduction device. The climbing frame is installed on the outside of the tower body, and the upper end is connected to the lower support with a pin shaft. It is a frame structure composed of welded steel and steel plates. To meet the safety requirements of jacking installation, a work platform is specially designed.
