Product Description:

1、 The MG type double girder gantry crane is suitable for loading, unloading, and handling in open-air warehouses, material yards, railway freight stations, port terminals, and other areas. It can also be equipped with various specialized hooks for various special operations.

2、 A crane consists of a bridge frame, a large vehicle operating mechanism, a small vehicle, electrical equipment, etc. The bridge adopts a box type double beam welded structure, and the large vehicle operating mechanism is driven separately. All mechanisms are operated in the control room.

3、 The conductive forms of cranes are divided into two types: cables and sliding wires. Users can choose one of them, and the data in the chart is based on the sliding wire.

4、 The normal operating environment for the crane of this system should be within the range of 25 ℃ to+40 ℃, and the average temperature within 24 hours should not exceed 135 ℃. The altitude of other installation and use locations shall not exceed 2000 meters, and if it exceeds 1000 meters, the motor capacity shall be checked.

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, it is necessary to clarify the industry, various size restrictions, environmental 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 Gn90% of the external suspension limit is required. 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 must be close to the supporting leg of the large vehicle before they can be operated. Small spans should not be operated outside the legs, and the wind pressure should be less than 150Pa.
