1. Plan the erection process: Before starting the erection process, a detailed plan should be made, including site preparation, tower crane assembly and dismantling. 2. Prepare the site: The site should be cleared of any obstacles and leveled to ensure a stable foundation for the crane. The crane's foundation should be designed according to the manufacturer's specifications and local building codes. 3. Assemble the mast section: The tower crane mast section is assembled on the ground and lifted...
A suspended platform is a type of Suspended Working Platform that is suspended from a building or structure using ropes, cables or chains. It is commonly used in construction, maintenance, and repair work on high-rise buildings, bridges, and other tall structures. The Suspended Cradle Platform is typically made of steel or aluminum and is designed to support workers, tools, and materials. It is suspended from the building or structure using a series of ropes or cables that are attached to a...
A tower crane is a type of construction tower crane that is commonly used on large building projects to lift and move heavy materials and equipment. It is typically mounted on a tall tower or mast and has a long horizontal jib that extends out from the tower. The crane operator sits in a cab at the top of the tower and controls the movement of the crane using a series of levers and pedals. Tower cranes are capable of lifting very heavy loads and can reach great heights, making them essential...
Luffing Tower cranes are especially demanded tall buildings on congested sites. They have a very short counter jib and a variable working radius, which permit high productivity in extremely narrow spaces. It's common to have limited space and clearance when working with a tower crane in an urban metro area and downtown work sites. A luffing tower crane is ideal for building projects where there's not much space on either side of the site and you need to work safely. A luffing crane is able to...

Alimak Galvanized VFD Construction Hoist SC200/200 1. Introduction of Construction Hoist A construction hoist is a lifting system often used at construction sites to lift personnel and materials to upper levels of unfinished buildings. The passenger hoist consists of a cage (or two) in which people will stand during transport, and a track that is mounted to the building. The cage will travel along this track by means of a rack and pinion drive system, and the cage can be stopped at various...
A luffing crane is a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius is highly reduced in comparison to standard tower crane types. The luffing tower crane also has a higher lifting capacity because the weight is transferred from the crane’s jib much more effectively. Topkit Tower Cranes also called hammerhead tower crane. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing...

SC series construction hoist is a vertical transporting equipment driven by Rack & Pinion, it is ideal for construction of high buildings, bridges, cooling towers, power stations and large chimneys. It is installed and dismounted conveniently, and can grow as high as the building grow in height. It has reliable electrical and mechanical safety device such as speed governor, overload limiter, various limits and interlock protector etc. It is efficient and safety vertical transporting...
Introduction of mast section The standard mast section of the tower crane consists of four independent steel frames. The four-beam type steel frame is connected together by a hinged hole bolt to form a standard section. Each type of steel frame is composed of a main limb, a fishtail plate, a diagonal web, a connecting plate and a gusset plate. BQ S24 model of tower crane mast section is 1.2m Tower Crane Mast Section, which could be used for Potain MC80 tower crane mast section. The main chord...
Topkit tower crane also called Hammer head Tower Crane is the tower crane with tower head. The tower head is the fulcrum of tie-bars chains connected to jib and counter jib. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing invulnerability and lowers the weight of jib & counter jib (simple transforming beam in mechanical model). This type of tower crane is lower in production cost, but is more demanding on the erecting and dismantling...
The anti-fall safety device is a crucial spare parts for construction hoist, it is consist of a circular cone, brake cone, spring, centrifugal weight and so on. When a cage is overspeed, the centrifugal weight will overcome the pressure of spring, causing the brake cone to rotate and the shaft pointed to brake cone will forward spirally. The friction force between the brake cone and crust will be increased gradually ensuring that the cage is stopped gradually. The anti-fall device is assembled...

A crane is a machine that is capable of lifting heavy goods to great heights with little human assistance. Depending on the nature of the project, cranes can either be fixed or mobile. Fixed cranes, as their name suggests, remain on-site for the duration of the project and must be dismantled before shifting to another location. Common types of fixed cranes include tower cranes and overhead cranes. What is a flat top tower crane? Flat top tower crane (Topless Tower Crane) is easy for assembly....
A luffing crane is also a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius is highly reduced in comparison to standard tower crane types. The luffing tower crane also has a higher lifting capacity because the weight is transferred from the crane’s jib much more effectively.

Safety Requirement for Construction Hoist Installation 1. Clean the erection site and fence it with railings. No admittance except on business, forbid constructing operation above the passenger hoist when installing to prevent anything fall down to the erection site. 2. There must be the person who has specific duty for installation. 3. Strictly forbid operating the construction hoist by non-working person during installing. 4. Operating hoist must be at the roof of cage, don't operate it in...
Topless Tower Crane is easier for assembly. Many topless tower cranes have been used on construction projects or near airports where overhead clearance is taken into a consideration. While luffing tower crane is a good choice for work sites where two or more cranes are working at the same time. This is because the slewing radius of luffing crane is highly reduced in comparison to standard tower crane types. The luffing tower crane also has a higher lifting capacity because the weight is...
1.The mechanical wear of wire rope is caused by the running of machine material. In the using process, the outer surface get in touch with the surface of the wheel groove, the drum, etc., causing wear, and the wire diameter will be thinned after the wear, and the outer steel surface of the wire is worn and smoothed. Wire surface wear contains single-sided wear and overall wear. 2.The bending fatigue fracture of the steel rope is caused by rope passing through the wheel groove and retracting of...
Jacking is an important work in the use of tower crane, and is also an accident-prone stage. Only by making full preparations and take the announcements during and after the completion of the construction, can we ensure the smooth progress of the work. There are some special notice for tower crane jacking: 1. Preparatory work before jacking of tower crane Prepare the mast sections to be added according to the required raising height of the tower, and line masts up along the jib. The on-site...
1. The air gap between the stator and rotor is very small, which is easy to lead to the collision between the stator and rotor. In medium and small motors, the air gap is generally 0.2mm ~ 1.5mm. When the air gap is large, the excitation current is also large, consequently affects the power factor of the motor. If the air gap is too small, the rotor may occur the friction or collision.Generally, due to the serious out-of-tolerance of bearing and the inner hole of the end cover is out of shape...
