Product Introduction
This machine is suitable for material loading, unloading, and handling in mining ports, railway freight stations, open-air warehouses, and can be equipped with various lifting devices for special operations.
main features
1. This machine consists of a gantry, a large vehicle operating mechanism, a small vehicle, and electrical equipment.
2. The gantry adopts a box shaped double beam and π - shaped leg welded structure, which is reliable.
3. The conductive forms of cranes are divided into cable drum type and sliding contact wire type (optional).
4. The car adopts irregular steel rail cables for conductivity.
5. All institutions are operated in the control room, which is convenient and flexible.
6. Standardization, universalization, and serialization of components.
When selecting this machine, please indicate the high and low temperatures and power supply of the working environment. Design changes can be made according to user requirements.
FEATURES
Hard gear reducer, imported rope, three in one transmission. Equipped with sound and light overload alarm, anti hook collision self stop secondary protector, circuit self check protector, overcurrent missing item protection, intelligent self stop limit and other comprehensive protections. The electrical appliance is contactless, with module speed control, and can achieve micro speed and dual speed. The operation and lifting are particularly smooth, and the electronic control is simple and close to frequency conversion function. The control panel (handle) adopts 12V voltage and 380V voltage. When the voltage is within+5~-10%, the electronic control can be used for a long time up to "2 million" times.
selection
By job level, use industry. No matter which level you choose, the first thing to do is to select based on the industry, calculate the number of starting and jogging cycles per hour, and indicate the practical time per day and continuous practical time (h). When selecting or signing, specify the industry, various size limits, ambient temperature, speed, time (h), whether it is intermittent, continuous, starting, and point/hour. The above requirements are for your reference. Reasonable selection, design, and matching can better improve work efficiency.
precautions
At the work site, when the crane stops working, the user should promptly lock the crane. The main switch of this crane is not equipped with any wires. It is strictly prohibited to use it for dangerous operations such as lifting high-temperature molten liquids, flammable, dry, corrosive, overloaded, dust, etc. The total length of the external suspension of the gantry crane is less than 1/3 of the total span, and the outer suspension limit is Gn90%. The crane can only operate when the heavy object is moved into the support leg. The weight Gn that needs to be reduced by 10-20% when the large vehicle is running outside the legs, and when the overhang exceeds 1/3 of the mid span, Gn should be reduced in sections. In the above situation, heavy objects can only be operated when they are close to the supporting leg of the large vehicle. Small spans should not be operated outside the legs, and the wind pressure should be less than 150Pa.
