Underslung Overhead Crane
Construction Industry
بلاروس
A customer from Belarus approached us for a جرثقیل سقفی تک تیر equipped with a dual-speed electric hoist to support daily lifting operations in the construction industry. After evaluating the workshop conditions, we found that the runway beams had no supporting corbels, so we customized a 5-ton Underslung Single Girder Overhead Crane fitted with an MD dual-speed electric wire rope hoist.
Following order confirmation, we completed manufacturing, performance testing, and factory inspections on schedule to ensure the crane met all quality and operational requirements. To comply with local regulations, the equipment was supplied with EAC certification and designed in accordance with Belarusian electrical and safety standards.
As the customer planned to install the crane independently, we provided a detailed installation manual, installation videos, and complete electrical drawings. With our technical support, the crane was successfully installed and commissioned, and is now operating reliably, significantly improving the customer's lifting efficiency and productivity.
Key Client Requirements & Project Background
- The customer required a Single Girder Overhead Crane equipped with an electric hoist featuring dual-speed lifting capability. Since the customer's workshop does not have runway support brackets for the crane operation, a customized solution was required based on the site conditions to ensure proper installation and reliable operation of the equipment.
- The project is located in Belarus, and the customer required the equipment to have EAC certification to comply with the market access requirements of Belarus and the Eurasian Economic Union. In addition, the customer expected the crane to be equipped with a comprehensive safety protection system to ensure safe, stable, and efficient operation over the long term.
- The customer planned to install the equipment independently, so we provided complete technical support documents, including a detailed installation manual, installation guidance videos, and electrical drawings, to assist the customer in completing the installation and commissioning process smoothly.
Customized Crane Solution & Supporting Services
1. Customized Equipment Parameters and Installation Plans
Based on the customer's actual lifting requirements and workshop conditions, we provided a tailored crane solution to ensure optimal performance and operational efficiency. The main specifications of the equipment are as follows:
- ظرفیت: ۵ تن
- Span: 12 m
- Lifting Height: 5.75 m
- گروه وظیفه: A3
- Hoist Model: MD Electric Wire Rope Hoist
- Lifting Speed: 8 / 0.8 m/min
- Hoist Traveling Speed: 20 m/min
- Crane Traveling Speed: 20 m/min
- Power Supply: 380V / 50Hz / 3Ph
- Ambient Temperature: -20°C to +40°C
This solution fully met the customer's needs. Since the workshop had no corbels to support the crane runway, we chose an Underslung Single Girder Overhead Crane, which allows the runway to be suspended from the building structure. This not only satisfied the customer's requirement for a Single Girder Overhead Crane but also solved the runway support issue.
The customer's steel factory lacks corbels for crane rail support. Ordinary single girder overhead cranes require column-mounted corbels to bear rail and crane loads, the standard installation condition.
Using standard cranes would mean costly column welding and corbel fitting, causing schedule delays, weakened steel structure and safety risks; otherwise standard cranes cannot be installed.
We provide a customized underslung single girder overhead crane tailored to client needs:
- No factory reconstruction required: The crane hangs directly under roof beams rather than column corbels, preserving the original structure with no renovation fees and faster installation.
- Light weight fits roof load limits: Lightweight design reduces dead load on roof beams compared to equal-tonnage standard single girder cranes.
- Retains full single girder crane performance: It keeps smooth running, flexible operation, large span, high space utilization and easy wireless remote control.
- Cost-effective and low-maintenance: No expensive structural retrofits cut total purchase and installation costs. Simple structure and universal spare parts ease upkeep and reduce long-term expenses.
2. EAC-Certified with Comprehensive Safety Protection Systems
The equipment is fully EAC-certified, meeting the market access requirements of Belarus and the Eurasian Economic Union (EAEU). The certification covers equipment design, manufacturing, and safety performance, ensuring compliance with local standards and supporting reliable long-term operation.
In addition, the crane is equipped with a comprehensive safety protection system, including:
- Overload warning and limiter
- Hoisting height limit device
- Low-voltage protection function
- Phase sequence protection function
- Emergency stop function
- Safety hooks with latches
- Rubber buffers
The above safety protection systems cover all operating phases of the equipment. They ensure operational safety while greatly improving the crane's running stability, reliability and working efficiency, enabling long-term stable operation.
3. Comprehensive After-Sales Support
To support the customer's independent installation, we provided a complete set of technical documentation, including a detailed installation manual, installation videos, and comprehensive electrical drawings. In addition, our technical team offered remote guidance and after-sales support throughout the installation and commissioning process. With our professional assistance, the customer successfully completed the installation and quickly put the crane into operation.
Project Outcomes & Supply Capability
- We successfully completed the manufacturing, testing, and delivery of the Underslung Single Girder Overhead Crane. Before shipment, the crane underwent strict quality inspections and performance tests to ensure it fully met the customer's technical requirements. The equipment was also supplied with complete EAC certification and complies with local safety and electrical standards.
- Designed to suit the customer's workshop conditions, the Underslung Single Girder Overhead Crane effectively solved the issue of having no supporting corbels for the crane runway beams. The crane is now operating smoothly and has significantly improved the customer's lifting efficiency and daily productivity.
