Introduction
A double girder overhead crane is an overhead crane with two girders (bridges) extending between the runways to accommodate the width between the cranes. End trucks are located at the end of each girder and move the girder and crane along the length of the runway as a whole. Typically, trolleys and hoists run on top of the beam.
Double girder overhead cranes have several advantages over single girder overhead cranes:
Double girder overhead cranes increase the hook height (the distance above the ground that the crane can lift) because the trolley is placed on top of the two girders, while single girder overhead cranes are usually designed with the crane suspended at the bottom flange of the crane girder.
Double-girder overhead cranes are high-strength cranes with a lifting capacity of 5 to 550 tons, which are used for lifting and handling operations in workshops, garages, maintenance stations, assembly plants, etc.

Main Structure and Feature
Mainly consists of a bridge, trolley, crane traveling mechanism, 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 cranes only have one set of lifting mechanisms. For 16/3.2～50/10t cranes, there are two separate main and auxiliary lifting mechanisms with two hooks.
The main hook is used for lifting heavy objects and an 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 the workpiece. Should pay more attention that never allowing two hooks to lift two objects at the same time. The weight of the object is forbidden to surpass the rated lifting capacity of the main hook when they work together.
Bridge Frame
Consisted of the main girder, end girder, walking board, column, testing cage, cabin, and its platform.
Main Girder
Welded box type double the main beam.
The main end beam is contacted by high-strength bolts.
The main beam can be a normal rail beam or an off-trail beam.
The metal structure adopts a steel pretreatment process, X-ray or ultrasonic inspection of the butt welds of the main beam’s cover and web.
End Girder
The end beam is a rectangular tube welded by a high-quality steel plate.
The main end beam is contacted by bolts.
The whole bridge is separated into two pieces for transportation and installation.
Others
Lay the track on the upper cover plate for trolley traveling.
Install the crane traveling mechanism on the side of the walkway which contacts with the main girder.
Install the trolley sliding wire on the other side.
There is a railing on the outboard of the walkway in order to ensure the operator’s safety during maintenance.
The cab usually hangs beneath the bridge with electrical control equipment in it and mainly for operator use.
Trolley
Consists of a trolley frame, lifting mechanism, 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 set of independent driving devices for single hook and two separate driving devices for double hook (main and auxiliary).
Lifting mechanism working principle, through high speed rotating of YZR type crane special motor, and gear coupling drive involute gear reducer. Then the low-speed shaft of the reducer turns the wire rope drum. As long as the control of motors and their positive and negative rotation can achieve the lifting function of the hook.
In order to ensure the security and reliability of the lifting mechanism, the brake is installed on the high-speed shaft of the reducer. And the load limiter is installed on the bearing pedestal which supports the drum to avoid overload. The mechanical drawing is as follows:
- Main overload limitation;
- Main lifting motor;
- Main lifting gear coupling;
- Main lifting drum;
- Main lifting brake wheel coupling;
- Main lifting brake;
- Main lifting reducer.
Trolley Traveling Mechanism
Trolley traveling mechanism working principle, the involute vertical gear reducer driven by a motor. The low-speed shaft of the reducer contacts to the active wheel of the trolley frame in the way of centralized driving. The motor adopts double-output gear and there is a brake on one end of it.
There are four wheels installed under the trolley. Two of them are active wheels and the others are driven wheels. Driving devices include
1. Motor; 2. Brake; 3. Reducer; 4. Compensating shaft; 5. Coupling; 6. Wheels, etc.
Crane Traveling Mechanism
There are four traveling wheels installed on each side of the two end beams. Two of them are active wheels and the others are driven ones. The driving device of active wheels is installed on the walkway. Here adopt two sets of symmetrical independent driving devices and we call them respectively driven.
The reducer adopts circular-arc gear one of which load capacity is higher than the involute gear reducer of the same type. All of the mechanisms adopt rolling bearing with A.C. electromagnetic block brake.
Driving devices include 1. Reducer; 2. Motor; 3. Brake; 4. Coupling; 5. Coupling; 6. Wheels, etc are shown in the mechanical drawing as follows:
The contaction of the mechanical parts all adopts gear coupling. In this way, it can work well by gear coupling compensated even if there is an error caused in manufacture and installation or deflection between the parts caused by bridge deformation when loading.
Active and driven wheel axle support on the angular bearing box for easy assembly and maintenance.
Other Equipment
Bumper
The crane bumpers are installed on both ends of the two end beams. The trolley bumpers are installed under the trolley frame, and usually polyurethane buffer. Also can choose according to customer’s requirement. Use to reduce the collision possibility between two cranes within the same span or the impact influence caused when the trolley reaches the limit position at both ends.
Crane Conductor Wire Frame
In order to prevent the hook or wire rope from colliding with the high voltage supply when the trolley runs at the limiting position, the crane conductor wireframe is installed on the end close to a power supply under the two main girders of the bridge.
Crane Pantograph
The pantograph is installed on the bottom of the main girder. The power line is installed in the three sets of current collectors to supply the power of the whole crane.
Electrical System
The electric control box layout is reasonable, easy to repair
Security trolley line or angle steel trolley line
External cables are equipped with mark line number
Trolley moving power is supplied by a flat cable
The conductor is I steel or C shape sliding line
Safety sliding touchline with high conductive rate and low-pressure drop; current collector with high speed.
Lifting and crane can be independently controlled; also can work separately or together.
Limit and Safety Switch
Crane traveling, trolley traveling, and lifting mechanisms are all equipped with limit switches to limit the travel distance of every mechanism.
The circuit will be cut off when the limit switch works, then the machine shuts down. It will move in the opposite direction when switches on the power again. Thus, ensuring safety.
n order to prevent the operators and maintenance staff from the accident, the safety switch is installed on the access door of the walkway which leads the way from the cab to the bridge, and also on the railing which leads to the end beam.
Operation Mode
