Steel Structure Workshop and EOT Cranes Exported to Ethiopian customer, the customer intends to install 2 set of Single Girder EOT cranes in the existing aircraft engine maintenance workshop for the disassembly and assembly of engines. However, the existing factory building structure has insufficient bearing capacity to meet the installation requirements of two Single Girder EOT cranes, and the workshop clearance height is too low.
Therefore, the client requested our assistance in designing a brand-new Steel Structure Workshop & EOT Cranes Exported to Ethiopian.(SINGLE GIRDER & DOUBLE GIRDER EOT Cranes).
Due to the insufficient load-bearing capacity of the original steel structure workshop, it is impossible to directly install the EOT crane. For this, there are two feasible solutions:
1. Add new columns beside the internal columns of the factory building to support the overhead crane. If the height of the existing factory building does not meet the usage requirements, it is also necessary to carry out the heightening treatment of the factory building simultaneously.
2. Demolish the original factory buildings and rebuild them.
We design the Steel Structure Workshop based on the maximum load of two EOT cranes (Electric Overhead Traveling cranes). The design of industrial steel structures must comply with relevant industry norms and international standards to ensure the safety and reliability of the structure.
Steel structures are typically composed of components such as steel beams, columns, diagonal braces and trusses, and their main materials are carbon structural steels of Q235B or Q345B type that comply with national standards.
The EOT crane adopts a double-girder structure. The crane will handle loads which average 50 percent of rated capacity with 5 to 10 lifts per hour. According to the customer’s requirements, three lifting mechanisms (2*6ton +1*2ton) will be installed on the main beam. The specific technical requirements for the lifting mechanisms (electric hoists) are as follows:
All hoists shall be electrically driven containing wire rope with machine cut drums and upper and lower lift limit switches.
HOIST MOTOR:Hoist motor shall develop sufficient power to lift the rated load at the specified speed. All motors shall be protected from overheating by thermal protectors.
GEARING:All gears shall be constructed of material of adequate strength and durability to meet the requirements
for the intended class of service and shall operate in an oil bath.Gear lubricant shall not require replacement for the normal life of the hoist.
ROPE DRUM:Drum shall be supported at each end by sealed antifriction Bearings.
ROPE AND DRUM GUIDE:The hoisting rope shall be of proper design and construction for hoist service. To assure positive winding of rope on the drum and to prevent rope overlapping and potentially dangerous groove peak contact, a hoisting rope guide shall be employed. Wrapping of rope shall not be permitted
LIMIT SWITCH:Bridge and trolley shall be equipped with a limit switch.This switch shall be adjustable to set the extreme upper and lower limits of driving motors.
