single girder gantry crane

SINGLE GIRDER GANTRY CRANE

1. Product introduction:
MH type all inclusive box electric single girder gantry crane is used together with hoist. The windward side is small. It is a good light door in open places and windy areas. There are two operation modes: free operation and ground operation. Lifting capacity gn=2t-20t, span l0m-30m, working environment below 40 ºC, working level 25%, wind pressure not greater than 125pa.
2. Technical features:
The transmission adopts a new generation of three in one system, the electrical appliance adopts contactless module speed regulation control, and can realize micro speed and two speed approach frequency conversion functions, so that the operation and lifting inching performance are particularly stable. It is equipped with overload alarm skew products, anti hook punching secondary protection, missing item overcurrent protection, etc. the operation console (handle) adopts 12V voltage to realize the multi-functional protection of the hoist and gantry crane. When the voltage is within 380v+5– 10%, the electric control can be used for “2million” times for a long time.
3. Selection principle:
Industry of use, starting, inching times /h, daily practical time h. It must be noted: light crane. Starting and inching are gn/10-80 times /h, gn/2-40 times /h, gn/1-15-20 times /h, times /h ÷ 2 under high temperature of 50 ºC and severe environment.
4. Precautions:
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, explosive, 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 mid span, and 90% of GN at the limit of the external suspension. The crane can only operate when the heavy object is moved to the support drive. 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 can only be operated when they are close to the outrigger crane. Small spans should not be run outside the legs.
