QTD jib tower crane

QTD 125 jib tower crane

QTD 125 jib tower crane

QTD 125 jib tower crane operating mechanism, luffing mechanism, slewing mechanism and metal structure. The QTD 125 jib tower crane is the basic working mechanism of the crane, which is mostly composed of the suspension system and winch, and some lift heavy objects through the hydraulic system. The operating mechanism is used to move heavy objects longitudinally and horizontally or adjust the working position of the crane. It is generally composed of motor, reducer, brake and wheel. The luffing mechanism is only equipped on the jib crane. The QTD 125 jib tower crane when the jib is raised and increases when it is lowered. It is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to rotate the boom and is composed of a driving device and a slewing bearing device. The metal structure is the framework of the crane. The main bearing parts such as bridge, boom and gantry can be box structure or truss structure, or web structure, and some can use section steel as the supporting beam.
QTD 160  tower crane

QTD 160 tower crane

QTD 160  tower crane is compiled in extremely diversified ways. In the past, China has made unified provisions on this. Although this regulation is still implemented, many tower crane manufacturers still have a set of expression. There are two main parameters expressed by tower crane model: one is the rated lifting torque, and the other  QTD 160  tower crane is the maximum boom length and boom end lifting weight. Several typical compilation methods are introduced as follows. There are three common classification methods: 1. Numbering method specified in the standard According to zbjo4008, the model composition of tower crane in China is: class group code + form + characteristic code + main parameter code. Class: Q - (from) Group: T - (tower) Type: upward swing jack up type Z - (self-propelled) Fixed G - (fixed) Internal climbing type P - (climbing) Lower swing jack up D (L)

Structural composition and function of the good price and quality Qtz100 tower crane

Structural composition and function of the good price and quality Qtz100 tower crane

Generally, according to the size of the good price and quality Qtz100 tower crane, there are different installation heights, and the space distance of this height decreases with the rise. When the distance is less than ten meters, the hoisting of the good price and quality Qtz100 tower crane starts to become difficult, which will affect the hoisting. Therefore, it needs to be raised to a certain height again, and this process is called jacking.

How to identify the quality of the Best SC type construction elevator products

How to identify the quality of the Best SC type construction elevator products

The first is the electrical components. Although the structure of the electrical components of the Best SC type construction elevator is very simple, the quality of the components must be good. Good quality components rarely cause problems, high safety, and higher prices. The second is load. In the early stages of design, the Best SC type construction elevator products are easily deformed and bent if cheap steel structures or other poor-quality materials are used.

Why does the good price and quality QTZ250 (7030) tower crane have the problem of the tower crane tipping over

Why does the good price and quality QTZ250 (7030) tower crane have the problem of the tower crane tipping over

Different types of cranes usually use lifting torque as the main control. When the working range of the good price and quality QTZ250 (7030) tower crane increases or the heavy object exceeds the corresponding rated load, the overturning moment of the heavy object exceeds its stable moment, which may cause the tower crane to collapse.
