Product Description:

1、 Mg double girder gantry crane is applicable to loading, unloading and handling of open warehouses, stockyards, railway freight stations, ports and wharfs. It can also be equipped with a variety of special hooks for a variety of special operations.

2、 The crane is composed of bridge, crane operating mechanism, trolley, electrical equipment, etc. The bridge is of box type double beam welded structure, the crane operating mechanism is driven separately, and all mechanisms are operated in the control room.

3、 There are two types of crane conductivity: cable and sliding wire. The user can choose one. The data in the chart shall be subject to the sliding wire.

4、 The normal operating environment of the crane of this system shall be within the range of - 25 ℃ ~ ＋ 40 ℃, and the average temperature within 24 hours shall not exceed 10.35 ℃. The altitude of other places of installation and use shall not exceed 2000 meters. If it exceeds 1000 meters, the motor capacity shall be checked.

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.
