QD Double Girder Overhead Crane Application

Applied to materials handling between fixed span, and it's one of the most widely used crane with the largest number of varieties of different specifications.
Widely used in carrying, assemble and unassemble of general weights, and also can equipped with various special hoists for special operation.
Forbid to use in the conditions as easily combustible, explosive, corrosive (acid, alkali, plating, steam, etc.).

Working ambient -25℃～+40℃, moisture ≤85%, altitude below 1000 meters, power supply 380V, 50Hz, 3phases (Adjustable according to customer's different requirement).

Note: For example, QD5t-10.5 m means general overhead crane with lifting capacity 5t and span 10.5m.

QD Double Girder Overhead Crane Structure

Mainly consists of bridge, trolley, crane traveling mechanism and electrical system, etc.

There are three main operating mechanisms: lifting mechanism, trolley traveling mechanism and crane traveling mechanism. And each of them is equipped with separate motors for their own drive. For 5 ton and 10 ton cranes, normally single hook crane and only have one set of lifting mechanism. For 16/3.2～50/10t cranes, there are two separate main and auxiliary lifting mechanism with two hook.

Main hook is used for lifting heavy objects and auxiliary hook can be used for lighter ones. And the auxiliary hook can also be used to help the main hook tip and turn over workpiece. Should pay more attention that never allow two hook lifting two objects at the same time. The weight of the object is forbid to surpass the rated lifting capacity of main hook when they work together.
