Electric Double-girder Bridge Crane
Double Girder Electric Overhead Crane is bridge crane with hook, suitable for indoor or outdoor fixed cross inter-cropping handling and transport work. Lifting capacity range 3T-50T, and it consisted with double girder bridge mechanism, traveling mechanism, trolley with frame and electrical parts and The lifting mechanism is equipped with CD/MD electric hoist with frame. Compared to single girder overhead crane, its structure is stronger, more secure use, so double girder overhead crane lifting capacity is larger.

Application
Electric double girder overhead crane is an important tool and equipment to realize the mechanization and automation of the production process in modern industrial production and lifting transportation.So the double girder overhead crane has been widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port and wharf, logistics and other departments and places.
By Control Mode
How you control your double girder overhead crane can impact both safety and efficiency. Different industries and workshop setups call for different control styles. Here are the common control modes available:
Manual Control
Simple and cost-effective. Operators use a direct manual interface, usually suitable for small workshops or places with minimal automation.
Pendant Control
This is the classic push-button control pendant. It allows operators to stand clear of the load while maintaining full control of crane movements. Pendant control is common across most industries due to its reliability and ease of use.
Cabin Control
For large spans or complex operations, a cabin mounted on the crane itself gives the operator a direct view of the load and surroundings. This is ideal for heavy industry or shipbuilding where precision is critical.
Wireless Remote Control
Increasingly popular for its convenience and safety. Operators can move freely around the site, controlling the crane from a safe distance. It’s great for hazardous environments or areas where visibility is limited.
How To Choose The Right Double Girder Eot Crane?
Choosing the right double girder eot crane is essential for maximizing efficiency and safety in your industrial operations. Here are some factors to consider when selecting a double girder eot crane:
Capacity
The capacity of the crane should be based on the maximum load you will need to lift.
Span
The span refers to the distance between runway rails. Ensure that the span of your crane matches your workspace’s width.
Lift Height
Determine how high you need to lift materials, taking into account any obstructions or limitations within your work area.
Speed
Consider how fast you want materials moved and lifted by the crane.
Duty Cycle
Choose an appropriate duty cycle based on how frequently you’ll use it during operation hours.
Safety Features
Look for essential safety features such as overload protection mechanisms, emergency stop buttons, and limit switches.
