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.

We are a professional manufacturer of all kinds of lifting equipment. Our company is located in Yangliu Town, the lifting hometown of Yangliu, at the foot of Mount Tai which is the world-famous top five mountains, with a registered capital of 51.7 million yuan.
We are mainly engaged in designing, manufacturing, installation, transformation and maintenance of various general bridge cranes, gantry cranes, metallurgical cranes, explosion-proof electric hoists, wire rope electric hoists, European cranes and other products.
We have strong technical force. The professional technicians with college or technical secondary school education account for 80% of the total number of employees. The high quality and technical level of the employees effectively ensure the rationality of the product technical structure, the progressiveness of the processing technology, and the technical performance and reliability of the products.
We have a lifting machinery research institute, equipped with advanced computer-aided design system and lifting equipment laboratory. We mainly cooperate with Beijing Lifting Machinery Research Institute and Shandong University to focus on the research, development and design of new crane products. Among them, the European standard crane has mature technology and reliable quality, and our products are exported overseas. At the same time, based on the advanced design theory and manufacturing technology of cranes at home and abroad, the original crane products and equipment have been fully redesigned. The new products have reached the same quality as international famous brands. The technological innovation has reduced the manufacturing cost and increased the market share.
Since the establishment, the output value, profits and taxes of our company have increased significantly. Our products were sold well in more than 30 provinces and cities across the country, and have been exported to more than a dozen countries such as Brazil, Iran, Pakistan, Nigeria, Tanzania and other African countries, which have been highly praised by users at home and abroad.
