AQ-QE 250T+250T Overhead Crane for Sale

AQ-QE Double Trolley Overhead Crane

The AQ-QE type double trolley overhead crane, as the name implies, is equipped with two hoist trolleys of equal lifting capacity, both of which can be used independently and simultaneously. The trolley overhead crane is capable of lifting hundreds of tons, and it performs the lifting work more efficiently and safely. The overhead trolley crane design is in line with GB / T3811 standard.

Functions of Overhead Crane Double Trolley

The double trolley bridge crane provides great flexibility for lifting long loads. The trolley mechanism which combines an electric hoist and a top running trolley provides two directions of load motion, up or down, left or right. The double trolley crane is composed of a main trolley and a secondary trolley, which can be used simultaneously for more complex operations, such as installation process. The double trolley can also be operated separately that functions the same with an ordinary single trolley bridge crane.

In actual engineering projects, there are often complex lifting situations that require two overhead cranes to work together, such as lifting long item. However, it will increase the construction cost of the plant. A double trolley overhead crane can perfectly solve such problems for clients. To get a free quotation, contact us online now!
