Overhead Crane Girder

1. Product Introduction:
 

Dejun brand Double Overhead Crane Girder series is a bridge crane installed on a trolley with a fixed electric hoist (seat type or hanging type) as the lifting mechanism. The structure is simple and light, and has the characteristics of compact size, low building headroom, light weight and small wheel pressure.The trolley electric hoist, also known as the monorail electric hoist, is a light and small lifting device that walks along a track suspended in the air and lifts heavy objects. Also called monorail electric hoist.

 

Double Overhead Crane Girder working types are light and intermediate, and the working environment temperature is -25°C ~ 40°C. It is suitable for factories, mines, workshops, warehouses and other workplaces within the range of medium and small lifting capacity. It is forbidden to use in flammable, explosive and corrosive medium environment, and the working class can reach: A3, A4.

3. Component:
 

The mechanical part of the Double Overhead Crane Girder with Electric Wire Rope Hoist Trolley is divided into three mechanisms: the hoisting mechanism, the trolley operating mechanism and the cart operating mechanism.

The hoisting mechanism (electric wire rope hoist) is used to vertically lift Goods, it is manufactured using high-grade materials that are resistant to wear and tear, corrosion, and rust.

 

The trolley running mechanism is used for lateral movement with a load;
 

The cart running mechanism is used to move the hoisting trolley and the goods longitudinally, so as to achieve the three-dimensional space for handling and loading and unloading goods.
 

Metal structure part: It consists of bridge frame and small frame.
 

Electrical part: consists of electrical equipment and electrical lines.

 

The crane is equipped with state-of-the-art safety features such as overload protection, anti-collision systems, and emergency stop buttons, among others. These features ensure that the crane operates safely and efficiently, minimizing the risk of accidents, injuries, and damage to property.

 

 

4. The difference between hoist trolley and electric hoist

 

The trolley on the Double Overhead Crane Girder generally refers to the whole body composed of running motor, hoisting motor, reducer, brake, overload limiter, drum, wire rope, hook (or spreader), electrical appliances, etc., and the working level is relatively high. The stability is very good, and the cost is also high.

 

Electric hoist is composed of motor, hoist main body, transmission, hook, sports car, and electrical parts. It is relatively flexible, has low working level and low cost.

 

Project	The trolley of a crane	Electric hoist
Shape	Motor, brake, reducer, reel, etc. Separately mounted on the trolley frame to form a whole	A machine that makes up a whole
Volume and weight	Generally large in size and heavy in weight	Flake
Elevating capacity	The lifting weight can be large or small	Small lifting weight, the maximum lifting weight of domestic electric hoist is 15 tons, the maximum lifting weight of 63 tons abroad
Speed control	A variety of speeds are possible with winding or electric motors	Squirrel-cage motor is used, which can be controlled by clicking, especially with 2-3 levels of speed
Control	Operate in the driver's cab	Button control on the ground, can also be operated in the driver's cab
Operating frequency	Hex bolt	The size is changeable.
Cost and maintenance	Generally high	Lower
Service	Call for expertise	General professional knowledge
