Product Description

 

Single girder gantry crane with electric hoist is a kind of small and medium-sized rail operation type hoisting machinery and it should proper matching use CD1 and MD1 type electric hoist.
Single beam/girder gantry crane is a common lifting equipment, mainly composed of gantry frame, trolley, crane walking mechanism and electrical system. It is widely used in workshops, warehouses, docks and other places for lifting and handling goods, and can be equipped with multiple lifting hooks or grab. In terms of form, there are mainly MH type and L type.

The basic structure of a single beam gantry crane mainly consists of the following parts:
1. Main beam
Made by welding a single box girder or I-beam, the structure is lightweight and has moderate load-bearing capacity.The span of the main beam is usually 5-30 meters and can be customized according to requirements.
2. Legs
It is divided into rigid legs and flexible legs (fixed on one side and slightly movable on the other side), suitable for different spans and uneven ground conditions.The lower end of the support leg is usually equipped with walking wheels or track wheels.
3. Crane trolley
Installed under the main beam, equipped with electric hoists (such as wire rope hoists or chain hoists) to achieve the lifting and lateral movement of goods.The trolley can be manually or electrically driven.
 

4. Walking mechanism
The driving mode is divided into manual, electric or hydraulic. Electric drive is achieved through motors, reducers, and wheels, ensuring smooth operation.
The track is usually made of I-beams or specialized crane tracks, laid on the ground or on supports.
5. Electrical system
Including control box, remote control or cab operating device, realizing lifting, walking and speed regulation functions.
 

Feathers:
1. Lightweight design
-The single beam structure is lightweight, easy to install, and suitable for small and medium-sized loads (usually 0.5-20 tons).
2. Strong adaptability
-It can be operated indoors or outdoors, and the track laying is flexible (ground or elevated).
3. Economical and practical
-The cost is lower than that of a double beam crane, and maintenance is simple.
4. Diverse operation methods
-Supports manual, remote control, or cab operation.

 

Application scenarios:
1. Workshop/Warehouse: Handling materials such as molds and steel.
2. Logistics terminal: loading and unloading containers or bulk cargo.
3. Construction site: hoisting prefabricated components.
4. Production line: Coordinate material transfer with the process flow.

Advantage:
1.Steel structure: Q235B/Q345B carbon structural steel with seamless once forming technology more strong and elegant. Suitable for different operation temperature;
2. Lifting mechanism: Reducer, drum, motors protection class F class, China or World top quality motor brands,customer can specify brand;
3. Hook: Finest steel forged hook, long using life;
4. Wheels: Vacuum casting, with compact structure, convenient maintenance, high transmission efficiency and long service life;
5. Travel mechanism: With China or world famous crane motor, reducer supplier;
6. Electrics: famous brand.

 

Safety device:
1.Weight overload protection device.
2.Top quality long time bearing polyurethane materials buffer.
3.Lifting limit switch and traveling limit switch.
4.Emergency stop system.
5.Zero voltage protection.
6.Phases protection device and so on.

The transmission adopts a new generation of three in one system, the electrical appliance adopts contactless module speed regulation control, and can realize micro speed and two speed approach frequency conversion functions, so that the operation and lifting inching performance are particularly stable. It is equipped with overload alarm skew products, anti hook punching secondary protection, missing item overcurrent protection, etc. the operation console (handle) adopts 12V voltage to realize the multi-functional protection of the hoist and gantry crane. When the voltage is within 380v+5-- 10%, the electric control can be used for "2million" times for a long time.
