What are the specific models of overhead cranes?

There are three types of overhead cranes: general-purpose overhead cranes, single girder overhead cranes, and double girder overhead cranes

General-purpose overhead cranes:

Serial No. Designation Trolley Designator

1 Hook Overhead Crane, Single Trolley QD

2 Hook Overhead Crane, Twin Trolley QE

3 Bucket Grapple Overhead Crane, Single Trolley QZ

4 Electromagnetic bridge crane, single trolley QC

5 Grab hook bridge crane, single trolley QN

6 Electromagnetic hook bridge crane, single trolley QA

7 Grab electromagnetic bridge crane, single trolley QP

8 Triplex overhead traveler bridge crane, single trolley QS

Single girder overhead traveler:

The lift mechanism, trolley operating mechanism and the loaded trolley are fitted to a single crane. The lifting mechanism, trolley running mechanism and large trolley running mechanism mounted on the bridge are three kinds of working mechanisms, which are usually electrically driven. General trolley running track for the straight line, the crane in the rectangular field operation; bridge crane type varied, the most common, the most typical is the general-purpose bridge crane. It refers to the hook, grapple or electromagnetic suction cups as a pick-up device for the general purpose of the bridge crane.

Double Girder Overhead Crane:

Consisting of two main parts: the bridge and the lifting trolley. Both ends of the bridge through the running device, supported in the plant or open yard over the elevated track, along the track longitudinal operation; lifting trolley in the main beam of the bridge along the trolley track transverse operation.
