Product Description:

QTZ50(5008) tower crane is hoisting and conveying machinery which is designed by fully utilizing the group technology, the combinational design technology and the finite element analysis technology and taking the tower crane microcomputer design platform as a tool and has excellent performance.

The crane is a horizontal-arm-rest trolley-amplitude upper-revolution hydraulic lifting type crane which has the effective amplitude of 50m and the maximum lifting moment of 500kN•m. The tower crane has the lifting height of 30m and the adhesion lifting height of 120m (2 magnification) during independent use.
All the speed indexes of the crane meet or surpass national standards.
The crane has the total installed capacity of 25.5kW, features advanced parameters, excellent and reliable properties, attractive appearance, high quality, simple and practical structures, advanced safety devices, convenient maintenance, safe usage and reasonable prices, and is ideal construction machinery for many medium-small construction enterprises.

The lifting boom and balance boom adopt cantilever boom structure, which reduces the hoisting modular and makes it more safe, convenient and flexible to install and uninstall, and reduces the requirements for hoisting equipment and the site.
2. Multiple special mounting brackets are available, which saves the installation time and ensures safe and quality installation.
3. The lifting boom adopts cantilever boom structure and variable cross-section materials, featuring more reasonable structural stress and long service life; and it is easier to make different combination of boom length.

Q:How many tons are tower cranes QTZ125?
The performance parameters and technical indexes of this machine are up to or better than the national standard. The maximum working range is 65m, height is 50m independent, attached type lifting height up to 180m, the maximum working range of 65 meters, the rated lifting torque 1200kN - M.The machine parameters is advanced, reliable performance, beautiful appearance, good quality, simple and practical structure, equipped with advanced safety device, convenient maintenance, safe use, reasonable price, is the ideal construction machine for construction enterprises.
Q:What is the inspection certificate for tower cranes?
Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate. As for the reasons, the main consideration is the actual needs.
Q:When the tower crane is installed in the fertilizer tank,
When the tower crane is installed in the fertilizer tank, is the elevation of the upper surface of the tower crane foundation flat with the elevation of the bottom of the new building? Or lower than the trough mark
Q:What kind of bodies are tower cranes made of?
First, the working mechanism of tower cranesThe working mechanism of tower crane is usually composed of lifting mechanism, luffing mechanism, slewing mechanism, hydraulic jacking mechanism and running mechanism.The hoisting mechanism to realize heavy vertical up and down movement; luffing mechanism and slewing mechanism to achieve weight moving in two horizontal directions; hydraulic lifting mechanism of standard section, increase or decrease, so as to increase or decrease the tower; range of weights can achieve walking mechanism in tower crane and force of arbitrary space motion.
Q:How many meters does the tower crane installation height require expert proof?
The mounting height of the tower crane is determined by the manufacturer's manual,It has nothing to do with experts,After the tower crane is installed, it needs to go through the provincial construction quality and safety supervision station, and the designated testing institution will meet the technical requirements of the production plant, and the method can be used only after the use of the permit.
Q:What is the difference between a jack up tower crane and a fixed tower crane?
The jack up tower crane is a tower crane (that is an internal climbing tower crane) that is added and reduced by its own special device, namely, the standard section of the tower (that is, the attached tower crane) or the whole climbing tower itself.
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
1. Tower crane consists of three parts: metal structure, working mechanism and electrical system. The three main technical parameters are lifting moment, lifting weight and working speed. Lifting moment refers to the boom as the basic arm length maximum amplitude corresponding to the rated lifting weight of product, product or maximum weight with the corresponding inflection point.
Q:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
