Structure and Characteristics of Double Girder EOT Crane

The double girder eot crane is mainly consists of bridge, trolley, crane traveling mechanism and electrical system, etc.
There are three main operating mechanisms for the overhead crane: 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, the double girder bridge cranes is normally designed with single hook crane and only have one set of lifting mechanism.
For 16/3.2 ton ～50/10 ton eot cranes, there are two separate main and auxiliary lifting mechanism with two hook, equipped on the double girder overhead crane.
The main hook is used to lift heavy objects, while the auxiliary hook is used to lift lighter ones. Furthermore, the auxiliary hook can be used to assist the main hook in tipping and turning over the workpiece.
It is important to remember that two hooks should never be used to lift two objects at the same time. When they work together, the weight of the object cannot exceed the rated lifting capacity of the main hook.

Bridge of Double Girder EOT Crane

Consists of main girder, end beam, walkway, railing, overhaul crane cage, cab and its platform, etc.

Main Girder

The double main girder, welded box girder, and camber all meet national specifications.
Q235B or Q345B steel is used.Equivalentto foreign steel type Fe37 or Fe52.
Lincoln welding and nondestructive testing are used for the main weld.

End Beam

The main girder andend beam is a rigid connection. The middle of the two end beams is detachable and bolted together.
For crane bridge with a long spenis divided into two sections foreasytransportation and installation.

Main girder of double girder overhead crane

Trolley

Consists of trolley frame, lifting mechanism and trolley traveling mechanism, etc.

Trolley Frame

Welded of steel plate with high intensity and strong rigidity.
Equipped with lifting mechanism and trolley traveling mechanism.

Lifting Mechanism

One independent driving device set for a single hook and two separate driving devices for a double hook (main and auxiliary).
The lifting mechanism operates on the basis of a high-speed rotating YZR type crane special motor and a gear coupling drive involute gear reducer. The wire rope drum is then turned by the reducer's low speed shaft. The lifting function of the hook can be achieved as long as the control of motors and their positive and negative rotation is maintained.
The brake is installed on the high speed shaft of the reducer to ensure the security and reliability of the lifting mechanism. To prevent overload, a load limiter is installed on the bearing pedestal that supports the drum.
The mechanical drawing as follows:

1. Main overload limitation;
2. Main lifting motor;
3. Main lifting gear coupling;
4. Main lifting drum;
5. Main lifting brake wheel coupling;
6. Main lifting brake;
7. Main lifting reducer

Trolley Traveling Mechanism

The vertical gear reducer is driven by a motor in the trolley traveling mechanism. In centralized driving, the reducer's low speed shaft connects to the active wheel of the trolley frame. The motor uses a double-output gear and has a brake on one end.
The trolley is equipped with four wheels. Two of them are driven wheels, while the others are active wheels.

Trolley Driving devices include 1. Motor; 2. Brake; 3. Reducer; 4. Compensating shaft; 5. Coupling; 6. Wheels, etc.

Crane Driving devices include 1. Reducer; 2. Motor; 3. Brake; 4. Coupling; 5.Coupling; 6. Wheels, etc.

Crane Traveling Mechanism

On each side of the two end beams, four traveling wheels are installed. Two of them are active, while the others are driven. The active wheel driving device is installed on the walkway. Here adopt two sets of symmetrical independent driving devices and we call it respectively driven.
The reducer uses a circular-arc gear, which has a higher load capacity than an gear reducer of the same type. All mechanisms use rolling bearings and an A.C. electromagnetic block brake.
All parts of the mechanism are connected by gear coupling. This allows it to function effectively even if there is a manufacturing or installation error or deflection between the parts brought on by a bridge that deforms under load.
Support for driven and active wheel axles on the angular bearing box for simple installation and maintenance.

Other Equipment

Bumper

The ends of the two end beams have crane bumpers installed on them. The trolley bumpers, which are typically polyurethane buffers, are mounted underneath the trolley frame. Additionally, options are available based on customer needs.
Use to lessen the likelihood of a collision between two cranes operating across the same span or the impact that results when a trolley reaches its limit at both ends.
Crane Conductor Wire Frame

To prevent the hook or wire rope from colliding with the high voltage supply when the trolley is in the limiting position, the crane conductor wire frame is installed on the end close to the power supply under the bridge's two main girders.

Crane Pantograph

The pantograph is mounted at the bottom of the main girder. The power line is installed in three sets of current collectors to power the entire double girder eotcrane.

Electrical System

The layout of the electric control box is reasonable and simple to repair.
Security trolley line or angle steel trolley line
External cables are labeled with the line number.
Flat cable provides trolley moving power.
The conductor is made of I steel or a C-shaped sliding line.
Safety sliding touch line with high conductive rate and low pressure drop; high-speed current collector.
The hoisting trolleyand overheadcrane can be controlled completely separately; they can also work together.

Limit and Safety Switch

Limit switches are installed in the crane traveling, trolley traveling, and lifting mechanisms to limit the travel distance of each mechanism.
When the limit switch is activated, the circuit is closed, and the mechanism is turned off. When you turn on the power again, it will move in the opposite direction. As a result, double girder eot crane safty is guranteed.
To protect the operators and maintenance personnel from an accident, a safety switch is installed on the access door of the walkway that leads from the cab to the bridge, as well as on the railing that leads to the end beam
