Our engineering team has successfully completed overhead crane installation projects in countries such as Egypt, Saudi Arabia, Argentina, Uzbekistan, and Algeria, earning wide recognition and praise from our clients.

Overhead Crane Installation

• Pre-installation preparation: Before lifting operations begin, we carry out comprehensive technical preparations. This includes on-site inspection of the lifting area, review of construction drawings, organizing the lifting team to become familiar with the installation procedures, and conducting safety and technical briefings for all on-site personnel.
• Main girder and end girder lifting and assembly: A suitable lifting plan is developed based on site conditions. The main girder and end girders are lifted and positioned in sequence, followed by welding or bolted connections. Installation engineers monitor bolt torque and welding quality on site to ensure structural integrity. Structural dimensions and elevations are checked to meet the design specifications.
• Trolley assembly and rail installation: Trolley components are assembled in sections or as a whole according to the assembly plan. Trolley rails are installed with precision, with adjustments made to rail spacing and elevation to ensure smooth operation. The wheel diameter, gauge, and running condition are checked on site, and positioning devices are fine-tuned accordingly.
• Electrical system installation and wiring: Cables are laid, and electrical cabinets and control boxes are installed in accordance with design drawings. On-site wiring ensures proper and standardized connections that meet safety requirements. The protection level and grounding measures of electrical equipment are thoroughly inspected.

In general, the installation of a однобалочный мостовой кран takes around 15 to 20 days.

The actual installation period may vary depending on several factors, such as the complexity of the crane structure, the number of units to be installed, the length of the runway, and whether we are also responsible for rail installation. In addition, external factors like weather conditions can affect the schedule. We will develop a practical and well-organized installation plan based on the specific situation to ensure an efficient, safe, and orderly installation process.

Installation Quality Inspection

After the overhead crane installation is completed, we will carry out a comprehensive inspection of all key components to ensure the equipment meets the standards for safe, stable, and reliable operation. The inspection covers the following aspects:

• Assembly quality of the crane’s metal structure joints
• Installation quality of the trolley rails assembled on site
• Installation quality of the trolley and bridge travel mechanisms assembled on site
• Installation and functional performance of safety devices

Overhead Crane Testing

To ensure that the overhead crane delivers reliable performance and meets safety standards before being put into operation, a series of tests are conducted after successful installation:

• Trial operation: Verify that the control direction of each operating mechanism matches the actual movement direction. Each motor is tested individually to ensure normal operation, with brakes, limit switches, and safety devices functioning accurately and reliably. When the hook is lowered to its lowest position, there must be at least two full turns of wire rope remaining on the drum. Collision protection devices, buffers, and similar systems must operate correctly.
• Static load test: This test checks the crane’s stability and load-bearing capacity. The crane lifts 1.25 times its rated load, with the load suspended 100–200 mm above the ground for 10 minutes. After the load is removed, the bridge structure is inspected for any permanent deformation.
• Dynamic load test: This test evaluates the performance of all mechanisms and braking systems. The crane lifts 1.1 times its rated load, and after testing, all components must show no cracks or damage, and all connections must remain secure for the crane to be deemed qualified.

Coordination Matters

To ensure the smooth progress of the crane installation, the customer is requested to complete the foundation work in advance according to the drawings, ensuring that key structures such as the rail layout meet the technical requirements.

Our on-site installation service fee is 1,200 RMB per engineer per day. The customer is responsible for the engineers’ round-trip airfare, visa, accommodation, and meals.

Please coordinate the site conditions in advance and arrange the necessary resources, including lifting equipment, power supply, tools, and personnel support, to facilitate an efficient and orderly installation process.

Overhead Crane Installation by Customer

For customers with the capability to install independently, we can provide technical documents upon request, including the installation manual, electrical diagrams, overhead crane drawings, and a list of required installation tools. Remote video guidance or online support is available to address any technical issues encountered during installation.

• Installation Manual: This manual details each step of the overhead crane installation process, including pre-installation preparations and precautions, connection of the main beam and end beams, alignment adjustments after end beam assembly, installation locations and methods for the electrical control box, limit switches, and cable festoon systems, as well as requirements for installing the buffer at the end of the crane runway. The comprehensive content offers clear and practical guidance to installation personnel, effectively minimizing installation errors.
• Connection of Wires: Electrical control box diagrams are provided for the crane, hoist, or trolley, along with detailed wiring instructions. The manual also explains wiring methods for safety devices such as travel limit switches, overload limiters, and counterweight limiters, ensuring a safe and standardized installation process.
