Features:

This series of products have features compact dimensions, low building headroom, light weight, and low wheel pressure.
This electric double-girder bridge crane uses fixed-type wire rope electric hoist for its lifting structure (the main hook and the sub-hook). These cranes are mounted on a two-wheeled trolley that is matched with a double girder bridge. They can be divided into two kinds: double speed crane and single speed crane. It is typically used in single speed if the user has no special request, which means single speed is most common during ground operation.
There are 144 specifications in two varieties: cab control and ground control (handle control and wireless control). There are two kinds of operation rooms: open operation rooms and closed operation rooms, and according to the actual situation-installation types, they can be divided into two types: left side installation type and right side installation type. In addition, there are three kinds of enter direction: front side, end side, and top side, so we can meet the user's choice in a variety of different needs.
This electric double-girder bridge crane consists of four main components: bridge, cart, trolley and electric accessory.
Lifting capacity is divided into1t, 2t, 3t, 5t, 8t, 10t, 12.5t, 16t, 20t, 32t, totally 10 tonnages.
The crane operation, trolley running and hoisting mechanism are all related to limit switches, which can prevent these mechanisms on movement stroke. So in this way we can guarantee the operation safety.
