Rail type container crane
This machine is suitable for loading, unloading and handling materials such as mines, ports, docks, railway freight stations and open warehouses, and can be equipped with a variety of lifting appliances for special operations.
Main features:
1. This machine is composed of gantry, crane running mechanism, trolley and electrical equipment.
2. The gantry adopts box double beam and π shaped outrigger welding structure, which is safe and reliable.
3. The conductive form of crane is divided into cable drum type and sliding contact wire type (optional).
4. The trolley adopts special-shaped rail cable to conduct electricity.
5. All mechanisms are operated in the control room, which is convenient, flexible and comfortable.
6. Standardization, generalization and serialization of parts.
When selecting this machine, please indicate the high and low temperature and power supply of the working environment. The design can be changed according to user requirements.
Technical features
Hard tooth reducer, imported rope, three in one transmission. It is equipped with audible and visual overload alarm, anti hook punching self-stop secondary protector, circuit self-test protector, overcurrent missing item protection, intelligent self-stop limit and other all-round protection. The electric appliance has no contact, the module speed regulation control, and can realize micro speed and double speed, the operation and lifting inching are particularly stable, the electric control is simple and close to the frequency conversion function. The console (handle) adopts a 12V safety voltage of 380V, and the electronic control can be used for "2million" times for a long time within + 5~-10%.
Selection method
Use industry by job level. No matter which level you choose, you should first choose it according to the industry, I calculate the number of starting and jogging cycles /h, and indicate the daily practical time and continuous practical time (H). When selecting or signing, it is necessary to clarify the industry, each limit size, ambient temperature, speed, time (H), whether it is intermittent, continuous, start, point /1h. The above requirements are for your reference. Reasonable selection, design and matching can better improve work efficiency.
matters needing attention
At the operation site, when the crane stops working, the user should lock the crane in time. There is no wire above the main switch of this crane. It is strictly prohibited to lift high-temperature molten liquid, flammable, dry, corrosive, overloaded, dust and other dangerous operations. The total length of the external suspension of the gantry crane is less than 1/3 of the total span, and the gn90% at the limit of the external suspension can be operated only when the heavy object is moved into the outrigger. The weight GN that must be operated by the crane outside the leg shall be reduced by 10~20%. When the external suspension exceeds 1/3 of the midspan, GN shall be reduced by sections. Under the above conditions, the heavy objects must be close to the outrigger crane before operation. Small span should not be operated outside the legs, and the wind pressure is less than 150pa.
