QTZ250 (7030) tower crane

QTZ250 (7030) tower crane

Model QTZ250 (7030) tower crane with lifting torque of 250tm.Tower crane: the boom form of tower crane is divided into horizontal type and pressure bar type. When the boom is horizontal, the truck runs along the horizontal boom and the luffing motion is balanced. The boom is long, but the boom weight is large. When the boom is of compression bar type, the luffing mechanism leads the boom to pitch luffing. The luffing motion is not as stable as the horizontal type, but its self weight is small. The lifting capacity of the tower crane varies with the amplitude. The product of lifting capacity and amplitude is called load moment, which is the main technical parameter of this crane. Through the slewing mechanism and slewing ring, the tower crane has large lifting height and large inertia mass of slewing and walking, so it needs to have good speed regulation performance. In particular, the lifting mechanism is required to be fast under light load, slow under heavy load and micro motion in place. Generally, in addition to resistance speed regulation, eddy current brake, frequency modulation, pole changing, thyristor and electromechanical combination are often used for speed regulation.

Qtz100 tower crane

Qtz100 tower crane

Qtz100 (tc6013) tower crane instruction manual qtz100 (tc6013) tower crane (hereinafter referred to as crane) is a new type of construction crane developed by Jinan Construction Machinery Co., Ltd. according to national standards. The machine is a multi-purpose crane with horizontal boom, trolley luffing and up swing. The standard arm length is 50 meters, the extended arm length can reach 55 meters and 60 meters, the maximum lifting capacity is 8 tons, and the rated lifting torque is 960 kn M, and the lifting torque is 1000 kn Meters. The main features of the machine are as follows: The climbing frame is mainly composed of frame, platform, hydraulic jacking device and standard section introduction device. The frame is sleeved outside the standard section of the tower body, and the upper end is connected with the lower support with bolts. It is 6.93m high and 2.3m in section × 2.3m is a frame structure composed of section steel and steel plate. In order to facilitate the safety needs of jacking installation, there is a special working platform. 16 adjustable rollers are installed on the inside of the climbing frame along the main chord of the tower body, which are supported on the outside of the main chord of the tower body. On the cross beam of the climbing frame, two padeyes are welded and hinged with the oil cylinder of the hydraulic system to bear the jacking load of the oil cylinder. The lower part of the climbing frame has two swing claws operated by the lever principle, which are used as the weight of the climbing frame to support the upper structure in the process of recovering the piston of the hydraulic cylinder and introducing the standard section. The upper and lower chords of the jib are square tubes welded by two angle steels. The whole jib has a triangular section, with a height of 1.2m, a width of 1.4m and a total length of 63.20m. It is divided into ten sections. The sections are connected by pins, which is convenient for disassembly and assembly. In order to improve the lifting performance and reduce the weight of the boom, the boom adopts double lifting points and variable section space truss structure. The trolley traction mechanism and hanging basket are placed at the first section of the jib to facilitate installation and maintenance. The first section at the root of the boom is connected with the slewing tower body with a pin shaft.
QTZ125 tower crane

QTZ125 tower crane

 Fushun Yongmao QTZ125 tower crane is a kind of up rotating fixed light tower crane, which can be widely used in various industrial and civil buildings, especially in construction sites with narrow site and complex terrain.

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.
