Overhead Crane Trolley

1. Product introduction:

 

The grab-hook overhead crane trolley is a double-girder bridge crane commonly used in bulk materials sites. The model is QN. This crane can not only use the grab bucket to grab various bulk materials, but also use the crane to grab various bulk materials. Hook to lift other heavy objects.

 

QN model overhead crane is a kind of crane which with two purposes for grab and hook. It is a combination of QD type bridge machine and QZ type grab crane.

 

The advantages of dual-purpose overhead bridge cranes include complex structures, strong load-bearing capacity, and the ability to adapt to lifting needs of different heights, spans, and loads. At the same time, it is simple to operate and has high safety performance, and operators can operate it at a safe distance. The disadvantage is that it costs more and requires certain space and infrastructure.

 

2. Parameters:

 

The basic parameters of The grab-hook overhead crane trolley include:

 

① Rated lifting capacity.

 

② Span. Also called span, it refers to the distance between two parallel tracks on which the The grab-hook overhead crane trolley travels. The span of the crane is generally 1.5m smaller than the span of the workshop. The span is divided into one level every 3m, from 10.5m to 31.5m, and the span greater than 31.5m is a non-standard span.

 

③ Speed. The speed is determined according to the busyness of the QN overhead crane trolley. The speed for light work is lower and the speed for heavy work is faster. If the lifting weight is small, the speed can be faster. If the lifting weight is large, the speed should be slowed down. Otherwise, it will be detrimental to safety.

 

3. Component:

 

The grab-hook overhead crane trolley has two lifting systems, which are mainly composed of metal structure, lifting trolley, trolley operating mechanism and electrical control system. The recovery device is the grab bucket and hook on the lifting cart.

 

The metal structure part of the bridge crane refers to the bridge and the trolley; The electrical part includes electrical equipment and power lines. After reasonable configuration of each device, the overhead crane can not only be used for loading and unloading in open warehouses, material yards, railway loading stations, port terminals, etc., but also can use grab hooks and buckets for different operations.

 

Grab bucket is a kind of search device for crane loading and unloading of bulk materials, which is mainly used for loading and unloading a large number of bulk objects. Its gripping and unloading are operated by the driver in the driver's cabin, without the assistance of auxiliary personnel.

 

The hook is the most common type of spreader in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism by pulley blocks and other components.

 

4. Applicable environment:

 

The grab-hook overhead crane trolley is widely used in various places and can be used for cargo handling and loading and unloading operations in docks, factories, warehouses, logistics centers and other industries. It is an indispensable piece of equipment in modern production and logistics processes, and can improve transportation efficiency and production efficiency. And its equipped hook can be used for assembly workshop, machining, metal structure workshop, as well as various warehouse lifting jobs.

 

Although the The grab-hook overhead crane trolley has a relatively wide range of work, there are also prohibited places. For example, it is strictly prohibited to be used in flammable and explosive operations, high temperature solutions, corrosion, overload, dust and other hazardous operations, and must also be operated in accordance with the general operating specifications of cranes.

 

 

5. Wear parts:

 

Wear parts of double girder The grab-hook overhead crane trolley include limit switch, shock absorber, carbon planer and rope guide.

 

6. How to operate The grab-hook overhead crane trolley?

 

The double girder overhead crane with trolley hook and grab bucket has two types of operation on the ground and in the air.
