Product Description:
This machine is suitable for loading, unloading and handling materials such as mine port wharf, railway freight station and open warehouse, and can be equipped with a variety of lifting appliances for special operations.
Main features:
1. the 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 reliable.
3. the 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 conveniently and flexibly in the control room.
6. standardization, generalization and serialization of parts.
When selecting this machine, please indicate the limitations of working environment, high and low temperature, power supply, etc. 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 operating console (handle) adopts a voltage of 12V and a voltage of 380V. When the voltage is within +5~-10%, the electric control can be used for "2million" times for a long time.
Selection method
Use industry by job level. No matter which level you choose, you should first select it by industry, I calculate the number of starting and inching cycles /h, and indicate the daily practical time and continuous practical time (H). During model selection or signing, the industry, various limiting dimensions, ambient temperature, speed, time (H), whether it is intermittent, continuous, start and point /1h must be specified. 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 operation, the user shall lock the crane in time. There is no wire above the main switch of the 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 limit of the external suspension is gn90%. The crane can run only after the heavy object is moved to the outrigger. The weight gn of the crane running outside the legs shall be reduced by 10~20%. When the external suspension exceeds 1/3 of the midspan, the GN shall be reduced by sections. Under the above conditions, the heavy objects must be close to the outrigger crane before operation. The small span shall not be operated outside the legs, and the wind pressure shall be less than 150pa.
