An overhead crane is a lifting equipment that is horizontally mounted above a workshop, production line, or warehouse to lift materials. There are many types of overhead cranes, and the structures and usage environments of different types of overhead cranes are also different. Below, we will introduce you to different types of overhead cranes, as well as applicable environments, components, prices, etc., which will help you better understand overhead cranes.
What Is An Overhead Crane?
An overhead crane is a type of lifting equipment that is horizontally mounted above a workshop, production line, or warehouse to lift materials. Can move heavy objects from point A to point B accurately and stably. It is mainly composed of one or two main beams, two end beams, a lifting mechanism, a Travel Mechanism, an electrical system, and other components. Because its appearance and structure resemble a bridge, it is called an overhead crane.
What Are The Different Types Of Overhead Cranes?
There are many different types of overhead cranes, including single-girder overhead cranes, double-girder overhead cranes, suspension overhead cranes, explosion-proof overhead cranes, etc. Below, we will provide you with a detailed description of different types of overhead cranes and their features.
Single Girder Overhead Crane
Single-girder overhead crane is a common light-duty lifting equipment, widely used in Production workshops, warehouses, Repair workshops, construction sites, and other places for lifting and moving materials. Typically, single girder overhead cranes have a load capacity of 1-32 tons.
Features: Single-girder overhead crane has the characteristics of small size, low cost, stable operation, high load-bearing capacity, and wide application range.
Double Girder Overhead Crane
A double-girder overhead crane is a large-duty lifting equipment. It consists of two main beams and end beams, an electrical system, a travel Mechanism, a lifting mechanism, safety devices, and other key components. It can be equipped with different lifting Spreader to suit different working environments, such as hooks, grabs, electromagnetic suckers, etc. Normally, the lifting capacity of a double-girder overhead crane is 5-320 tons. It can also be customized with a higher lifting capacity according to actual usage.
Features: Double-girder overhead cranes have the characteristics of strong carrying capacity, stable structure, smooth operation, safety, and reliability. They are suitable for large-tonnage, high-frequency heavy-duty material handling operations. Its key components adopt a modular design, which is convenient for later maintenance and overhaul, effectively reducing downtime.
LX Type Electric Suspension Overhead Crane
The LX type single-girder suspension crane is mainly used in locations where no columns can support the overhead crane. The end beams of the it ride on the bottom flange of the runway beam. Typically, a suspension bridge crane suspends one the roof of the building and is available only for lighter capacities, no more than 10 tons.
Features: The LX type electric Suspension overhead cranes have the characteristics of saving space, simple installation and operation, lightness and flexibility, low production cost, and easy later maintenance.
European FEM Standard Overhead Crane
European FEM standard overhead crane is a kind that meets European design standards and the advanced technology of the bridge crane. Different from traditional overhead cranes, the maximum distance from the European Electric Hoist to the wall is smaller, lower clearance height. And European bridge crane can be closer to the front for operation, with a higher lifting height. European bridge cranes are divided into single-beam and double-beam types. You can choose the equipment that suits your production environment according to your specific needs.
Features: European bridge crane adopts modular design, which has of compact structure, small footprint, small operating limit size, high load-bearing capacity, and low energy consumption the features.
Explosion Proof Overhead Crane
The explosion-proof overhead crane is a kind of lifting equipment specially used in flammable and explosive environments. With all the motors and electrical equipment of it is manufactured in line with international standards and regulations. These parts are constructed with special safety features. Explosion-proof bridge cranes are divided into single-beam and double-beam types. You can choose the equipment that suits your production environment according to your specific needs.
Features: An explosion-proof bridge crane is a specialized piece of equipment designed for use in flammable and explosive environments. It features an explosion-proof structure, safety protection, high sealing, corrosion-resistant materials, stable operation, and complies with international explosion-proof certification standards.
What Are Overhead Cranes Used For?
An overhead crane is a common lifting equipment, mainly used for the transportation and handling of materials and goods. It is widely used in machinery production workshops, construction sites, warehouse logistics, steel mill industry, petrochemical industry, etc. The following are its main application scenarios and uses:
Machinery production workshops: Used to lift raw materials, semi-finished products, finished products, or large parts to achieve material transfer between each process and improve production efficiency.
Construction sites: Mainly used for lifting precast structural components, steel structure installation, and building material handling.
Warehouse logistics: Responsible for the loading and unloading, stacking, and transportation of goods within the warehouse, etc. Effectively improve the utilization rate of warehouse space.
Steel mill industry: Support the handling of raw materials, semi-finished products, and equipment in steel mills and foundries.
Petrochemical industry: Equipped with an explosion-proof bridge crane, it is used for equipment installation, storage tank lifting, and dangerous goods handling.
Electronics Industry: Cooperate with automated production lines to assemble electronic components with high precision.
Repair workshop: Responsible for tasks such as disassembly and assembly of heavy equipment, lifting of parts and components, and assistance in maintenance operations to improve maintenance efficiency and ensure the safety of operators.
What Are The Parts Of An Overhead Crane?
The overhead crane mainly consists of components such as the main beam, rails, end girders, hoisting mechanism, trolleys, control system, and electrical power systems other parts. The functions of each spare part are described as follows:
Main beam: Installation of rails for lateral movement of the trolley.
End girders: Mounting Bridge crane Travel Mechanism.
Trolley Travel Mechanism: Responsible for the lateral movement of the trolley.
Overhead Travel Mechanism: Responsible for the longitudinal movement of the crane.
Hoisting mechanism: Used for the vertical movement of goods.
Control system: The system used to operate the crane, including hitch controls (hand controls), remote control, or cab controls.
Electrical power systems: Provide power support for the crane, including motors, cables, and power distribution units.
Walkway: Walking paths for overhaul and post-maintenance.
