The crane or crane is mounted on a rectangular truss that can move flexibly across the workshop. What is crane? Crane is a lifting device used to lift, lower, move goods in the factory, factory safely and securely. Crane lifting capacity from 1 ton to 500 tons is operated mainly by electric motor, so it is used in many industrial factories. Lifting equipment is electric winch or steering wheel mounted on a car or moving cluster along the crane. The lifting equipment runs on I-rail, on the flap under the main beam, running on the flap on the main girder. The crane operator is controlled manually using an electric drive system.
Crane is a lifting device used to lift, lower, move goods in the factory, factory Classification of crane Depending on the use, the design will have different types of cranes. Single girder 2-ton crane: Consists of an I-beam attached to two running girder tracks and one end truck, using a manual winch drive mechanism or by electric pallet running under the girder. Double girder overhead crane: The crane uses two beams together with the upper trolley or double girder Palang, which increases the lifting height of trolley or pallet. Box girder overhead crane: Using box shape in the fabrication of crane girder, helps increase load. The base of the girder is fitted with wheels to move. Gantry girder overhead crane: Designed to reinforce larger girder structure to increase load as well as aperture. A-shaped crane: Designed in the form of a triangular cylinder with wheels moving under the girder's foot. A-shaped cranes are usually installed at cargo terminals such as timber and containers at seaports. Tower Crane: A very large crane with large tonnage, often used at construction sites or for loading and unloading containers. Stacking crane: The crane type is equipped with a specialized lifting mechanism.
A-shaped crane is designed as a triangular pillar with wheels to move under the girder's foot.
The devices come with cranes
Coils or hooks C: Used to lift and lower coils of steel, corrugated iron in steel factories.
Grabbing: Used for mining factories, for wood scooping in hydroelectricity, scooping in steel mills often using mechanical or hydraulic systems.
Magnetic rims: Using magnetic fields to lift and lower types of steel, used in steel factories, mechanical processing.
Lifting beam: Support tool when lifting lever at the same time with two key points that the crane has only one lifting angle.
Crane price
In order to have the crane rack or the shaft gate, the user must know the purpose of use, the lifting height, aperture, operating time and working speed, working environment, noise ....
Once you know the requirements of the factory owner, businesses care about price and quality. The factory uses expensive cranes but little use will be wasteful, using cheap cranes that do not meet the standards and using 24/24 will lead to continuous maintenance, costly to stop production, causing damage. furniture for business.
For the above reasons, when investing in gate cranes, the cost of equipment is mainly different, mainly for equipment such as hoist, winch, trolley and crane accessories, and the structural part has a fixed price (main beam, border, track ...).
