Overhead Crane Project Introduction of Pipe-Making Plant

Since 2016, Ethiopia economy has been developing rapidly, the government support lots industries to establish their new workshops, so Mr Ashenafi built three new warehouses for pipe making. We Dongqi Group contacted Mr Ashenafi from the beginning of January, 2016, after learning the crane needs of pipe-making warehouse, our sales director Mr Oscar was responsible for giving below solutions:

10 Ton Overhead Crane Drawing

Mr Ashenafi was very satisfied with above crane solution, after a period of communication about some crane technical question, then sign the contract at the end of 2016 and totally amount is US DOLLARS 143,000.00.

Crane Installation Engineer Reached to Ethiopia

On 8th May, Our technical team visited our Ethiopia customer Pipe-Making Plant, for installation and commission of 6 sets 10 ton double girder overhead crane, which is shipped and arrived customer’s plant last year, on that day Mr Ashenafi arrange people to pick Mr Chen up at the airport.

Preparation before Overhead Crane Installation

On the second day after arrival, Mr Wei request to go to warehouse to check all the overhead crane girders, boxes, electrics boxes, beams and rails and other crane spare parts which could ensure all crane parts are ready, then Mr Chen had a meeting with Mr Ashenafi and his team, Mr Wei told them to prepare related overhead crane installation tools, such as mobile crane, welding machine, screwdriver, forklift, lever etc, and how many people it will need to ensure the overhead crane installation process operate smoothly.

10 Ton Overhead Crane Installation Process

The 6 sets overhead crane will be used in three warehouse:

  • Firstly Mr Chen arrange one small team to lifting the beam, rails on the brackets, then welding them well;
  • Secondly Mr Chen adjust the rail centers distance to ensure the overhead cranes can be settled well;
  • Thirdly, Mr Chen arrange forklift driver to assemble these crane girders together, then asked mobile driver to lift the girders on crane rails well. After that, lifting the hoist trolley on the two main girders; at last Mr Chen connect the electrical cables in person to ensure the cables connections everything goes well.

Until 31th May, 5 sets overhead crane installation have been finished well, the other set will need extra 3 days, after that, Mr Chen will arrange the heavy load to commission the crane and adjust the working stability. After all installation and commission finished, he will teach the workers how to operate and maintain these overhead cranes, everything goes smoothly during the overhead crane installation, commissioning and inspection.

Welcome to Check Dongqi Overhead Crane

Our team has talked with Mr Ashenafi after all overhead crane installation finished, he agreed other customers to visit his plant to see our overhead cranes, so all Ethiopia customers and friends, if you have any cranes projects or want to know more of our company and our cranes, welcome to contact us!

What are the precautions for the overhead crane installation process?

overhead-crane-installation-precautions.jpg

Hoisting machinery is a special type of equipment and has a high degree of danger. Therefore, in the installation of cranes, safety work is particularly important. Special attention must be paid to the following aspects:

  • Most of the cranes are mechanical devices with large structures and complicated structures. Usually, it is difficult to transport the entire crane. It is often the entire assembly of the equipment that is transported to the site of use. Therefore, it must be properly installed to reflect the overall eligibility of the crane in order to verify the integrity and integrity of the crane.
  • The overhead crane is to be operated on the track of the use site or the building. Therefore, for the operational track or the installation foundation, and whether the crane itself can work well with each other, whether the operation is adaptable and whether it can meet the strict requirements for use, it must be concluded through proper installation and commissioning and inspection after installation.
  • The safety requirements of cranes are extremely high, and the safety devices must be perfect and installed correctly to achieve reliable, flexible, and accurate technical requirements.
  • According to the importance of crane safety work, in order to enable the crane to meet the operational requirements of various loads after being put into use, the crane must be tested for no-load, full-load, and overload static load and dynamic load in accordance with regulations. However, these tests must be carried out in the operating state or in a certain stationary state of the crane mechanism. This requires the use of a load test after the crane has been installed.
  • The overhead crane's wire ropes and other flexible parts and many other parts will undergo some elongation, deformation, looseness, etc. after the initial load. This also requires repairs, adjustments, handling, and tightening after the crane has been mounted and the load has been tested. Therefore, it is necessary to do a series of work such as crane installation, commissioning, and speed control to ensure safe and normal use of the crane in the future.

What are some common welding defects during crane installation?

The overhead crane needs to be welded during the installation. The quality of the welding directly affects the performance of the crane. If there is a defect in the welding, it may cause the welding place to be weak, prone to cracking, reduce the working strength of the welding part, and in serious cases it will cause a safety accident. Therefore, attention should be paid to the welding defects of cranes. Several common welding defects during crane installation are as follows:

  • Collapsed

In the welding process, single-sided fusion welding is performed. Due to unreasonable welding processes, such as improper groove processing, unreasonable selection of current welding speed, etc., a large amount of weld metal is transmitted through the back surface, resulting in the collapse of the front surface of the weld seam. The back of the seam appears raised and this side is collapsed. After the collapse occurs, the strength of the weld will decrease and the stress will be too concentrated.

  • Burn-through

During welding, due to excessive heat input, such as wire feed too fast, the torch running too slowly, etc., the molten metal flows out from the back of the groove, forming perforations in the weld, which is burned through. Burn-through is a common welding defect, especially when welding some thin plates. Welds that have burned through will not be guaranteed for continuity and compactness and should be repaired as soon as possible.

  • Weld beading

Weld beading refer to the fact that during welding, due to improper operation, such as excessive current and slow welding speed, the molten metal flows to the base metal outside the weld and does not melt. The deposited metal formed on the edge of the weld and the base metal things. The inside of the weld has no penetration, affecting the welding quality.

  • Arc crater

When performing arc welding, due to arc extinguishing, arcing or arcing is not reasonable and other reasons lead to low enthalpy at the end of the weld bead. The occurrence of craters will reduce the strength at the end of the weld and reduce the weld cross-section.

  • The size is not reasonable

Welding feet and welding throats are of reasonable size and have not reached the specifications and specifications specified in the sample drawings. If the dimension is too small, the strength of the weld seam will be reduced. If the dimension is too large, the deformation will increase.
