Electric Single Girder Overhead Crane 15ton Span 22m
The A5 European crane excels in efficiency, durability, and performance for heavy-duty cycles, while the A3 traditional crane is a cost-effective solution for lighter, less frequent operations. The A5 design emphasizes precision, energy savings, and reduced downtime, making it ideal for modern industrial applications.
Design Details of single girder Overhead Bridge Crane
The wheels on top running bridge crane operate on either T-rail, square, or rectangular rail. They tend to have a longer wheel and bearing life expectancy than underhung cranes of the same type and capacity.
A top running overhead crane offer excellent headroom advantages over other styles of cranes due to the extra lift height that is gained by having the crane girder on top of the endtrucks rather than suspended from the bottom of the trucks as in underhung applications.
A top running single girder crane that require spans to exceed 60 to 85 ft. are likely to be a box girder constructed crane. Box girder cranes have a very light weight to span ratio and in many cases can reduce the size of the runway and building structure required to support them. These cranes are often referred to as mono box bridge cranes.
Single girder motorized bridge crane utilizes underhung hoists such as electric wire rope hoist or electric chain hoist. All motorized bridge cranes include electric festoon systems unless otherwise specified.
1,Main Girder
The main girder is a box type structure with compact design, lighter weight ,higher working grade and reasonable distribution of stiffener. The span can be divided to several parts when span exceeds 12 meters, which is convenient for container shipment.
2,End Carriage
The main body of the end beam is made of rectangular tube, and the wheels are of two structures: hollow shaft or open gear type. It is matched with different levels of drive motors, which is beautiful and runs smoothly.Equipped with a magnetic infrared anti-collision limiter with adjustable distance.
3, Control Panel
The circuit layout of the electrical control panel is reasonable, neat and beautiful. The logn traveling is controlled by a frequency converter, making the operation and stopping smoother.
4, C-track festoon
Festoon Systems support conductor cables(flat or round) and hoses (hydraulic and pneumatic applications) for delivering power &control to mobile equipment in a safe, efficient and maintenance free method.
The cable trolleys are well guided inside their C-tracks and protected against humidity, dust and icing.
cable trolleys not only deliver power and control to mobile equipment which has reciprocal motion but also support large quantities of data cables including optic fibres travelling independently from the moble machinery .
5, Lifting Mechanism Electric Hoist
Lifting mechanism: The lifting mechanism adopts European wire rope electric hoist or electric chain hoist, which has lower noise and higher working level. Use pendant control or wireless radio remote control.
