Materials Handling Equipment, Single Girder Overhead Crane

Overhead crane (bridge crane) is developed rapidly with world technology and fast changed design concept.

Same like many other manmade tools, at the beginning of overhead crane turned up in history, overhead is mainly set up to be an equipment of many mechanisms that handling material is its main and only function.

As time passing by, customers have been putting forward new requirements on old overhead crane, such as power sauce, lifting speed, travel speed, wider span, and heavier lifting capacity. Thus electric overhead travelling crane (abbreviated as EOT Crane), even manual overhead crane, all show up. What's more, aesthetic conception is introduced to bridge crane design, too. Most modern electric hoist, known as its small size, beautiful look, and compact structure, has caught many buyers' eyes. And it, in a certain extent, replaces winch trolley to be lifting mechanism, especially when lifting load is not that heavy. (Capacity of Weihua's electric hoist ranges from 250k to 80ton, but winch can lift up to 1750t )

China is always a place where miracle exists. Our pioneers, they created a new style electric hoist, CD1, short after that, MD1 shew up, too. These two hoists have served china for tens of years.

In recent years, a very fashionable, high grade electric hoist have appeared in public, it started from west Europe, and soon spreads to the whole world, it is so attractive because 3 peculiar features:

1. High profile, with very good and original configuration.

2. Very good outlook.

3. Compact size and little space occupation

However, compared with Chinese CD1, and MD1, its disadvantage is also significant, that is price difference is much. So, ND hoist is only sold to those customers that have space limit, and more precise positioning requirement. In order to contend for market, CD1 and MD1 hoist is improving too by adding frequency converter, and customized motor. Some even changed their shape or original mechanism position to minimize headroom.

HD electric single girder overhead crane and NLH electric double girder overhead crane are the most advantaged single girder overhead crane designed and developed by Weihua group and Singapore crane designing company, it complies with DIN, FEM, ISO standards. This crane features strong stiffness, low dead weight, and outstanding structure design, particular travel system, etc, which can effectively save workshop investment and dimensions.

HD and NLH could widely use in industries of machinery manufacture, metallurgy, petroleum, petrochemical, port, rail way, aviation, power plant, food, paper mill, construction material, electronic workshops, warehouse and other indoor material handling area. It especially suits precise material handling occasions like big and heavy important component installation.

Temperature of working environment shall be -25~40
