20 Ton LH Model Double Girder Overhead Travelling Crane
LH Model Double Girder Overhead Travelling Crane Introduction
The LH Type Electric Double Beam Electric Bridge Crane is designed and manufactured according to the national standard JB/T3695-2008 "Electric hoist bridge crane". It uses a fixed wire rope electric hoist as the lifting mechanism and is installed on the centrally driven double-track trolley, which is connected with the double-girder bridge. Matching double girder overhead crane. Similar in structure to the electric double-girder bridge crane, it is composed of four main components: bridge frame, trolley, cart and electric.Compared with the double-girder bridge crane, the LH Type Electric Double Beam Electric Bridge Crane has the advantages of compact size, low building headroom, light weight and small wheel pressure.
This product is mainly suitable for transfer, assembly, overhaul and loading and unloading operations in machining workshops, auxiliary workshops of metallurgical plants, warehouses, stockyards, power stations, etc. It can also replace ordinary double-girder overhead cranes for production workshops in light textile industry and food industry. The working type is light and intermediate, the working environment temperature is -20-40 ℃, and it is not suitable for flammable, explosive and corrosive medium environments.
LH Type Electric Double Beam Electric Bridge Crane has two forms of cab control and ground control. There are two types of operation room: open type and closed type, which can be divided into two types of left or right installation according to the actual situation. There are three types of entry directions: side face, end face and top, so as to meet the user's choice in different needs.
