A 1.5-ton low-headroom hoist inquiry was received from a customer from Serbia. The client, a well-known Serbian automotive parts manufacturer, planned to upgrade the crane system at its modern new factory in Belgrade.
Project Background | The “Stringent” Requirements of a New Serbian Factory
The workshop ceiling, densely packed with ventilation ducts, cable trays, and fire protection systems, severely limited the installation headroom for the electric hoists. So, the Serbian client’s new building structure factory presented significant challenges for the procurement team.
Traditional wire rope hoists, due to their drum structure, require a large amount of overhead space, significantly reducing the effective lifting height and failing to meet production requirements.
Therefore, the client clearly listed three non-negotiable core requirements in the tender documents:
1. Ultra-low headroom: The structure of electric hoists must be extremely compact to achieve maximum lifting height within a limited space.
2. Compliance with European standards: The lifting equipment must comply with European design specifications, featuring a compact structure, light weight, smooth operation, and ease of maintenance.
3. Complete CE certification: Complete CE certification documentation must be provided to ensure compliance with the EU Machinery Directive, which is the “passport” for the lifting equipment to operate legally and safely in the Serbian and European market.
Hoist Solution | Why Choose DR-type Electric Chain Hoists?
To meet the client’s specific needs, we recommended the DR series European-style electric chain hoists and provided detailed technical solutions that addressed every pain point.
1. Addressing the “Ultra-low headroom” challenge: A perfect balance between structure and space.
Core advantages: The DR electric chain hoist uses a sprocket lifting mechanism. Compared to wire rope hoists that rely on drum winding, its lifting mechanism (sprocket and chain) is extremely compact. This minimizes the distance between the hook tip and the track (headroom).
Customer Value: Our CAD drawings clearly demonstrate that, within the same factory clearance, DR electric chain hoists achieve nearly 30% greater effective lifting height than traditional electric hoists. This allows customers to handle taller workpieces or accommodate larger components in the future, significantly improving space utilization and production flexibility.
2. Adhering to European Standards: A Paragon of Quality and Design
Compact and Lightweight Design: The DR type low headroom electric chain hoist boasts a stylish appearance, compact size, and light weight, reducing the load on the factory structure and ensuring smooth and efficient trolley operation.
High Performance and High Reliability: Utilizing high-quality motors conforming to IEC standards, heat-treated alloy steel chains, and FEM-compliant mechanical structures, stability and long service life are ensured even under frequent start-stop and heavy-load operation.
Easy Maintenance: Modular design simplifies daily inspections and maintenance, reducing long-term operating costs for customers.
3. Adherence to CE Certification Standards: Legal Guarantee of Safety and Compliance
CE certification is more than just a certificate; it represents a complete compliance system. We provide customers with:
* A complete CE certification certificate.
* Detailed Technical Construction Documents (TCF): Includes design drawings, production drawings, test reports, and component certificates of conformity.
* EU Declaration of Conformity (DoC): This is the manufacturer’s formal legal declaration of product conformity.
* All safety devices, such as overload protection, dual braking systems, and upper and lower limit switches, meet CE requirements, providing double protection for the customer’s safe production.
Collaboration Results | Exceeding Expectations
After rigorous technical review and sample testing, our DR electric chain hoist solution successfully won the bid. After installation and commissioning, the hoist equipment’s performance fully met the customer’s expectations.
* Space challenges resolved: Optimized production line layout, eliminating all clearance restrictions.
* Significantly improved production efficiency: Smooth and efficient operation ensured a stable production rhythm.
* Successful audit pass: Complete CE certification documents enabled the customer to successfully pass subsequent audits by EU clients and international system certifications.
In international industrial procurement, every successful case perfectly demonstrates how product performance can precisely match customer needs. Our recent collaboration with a large Serbian manufacturing company vividly illustrates how DR electric chain hoists can be key to solving specific engineering challenges.
The DR type low headroom hoist is a type of lifting equipment designed in accordance with European standards specifically for environments with limited space. It is characterized by its compact structure and low height, making it suitable for places with restricted headroom. The low headroom chain hoist typically uses chain as the lifting mechanism and feature light weight, low wheel pressure, and a high safety factor.
The working principle of low headroom chain hoists is to drive the chain drum by the motor, causing the chain to rise or fall, thereby achieving the lifting of heavy objects. Its core advantage lies in the ability to complete efficient lifting operations in limited spaces, while also featuring high safety and economy.
The low headroom chain hoists are particularly suitable for places with height restrictions, such as low-rise factories, basements, and areas with dense equipment. Their compact design enables them to operate flexibly in narrow spaces while maintaining a high lifting capacity. Additionally, low headroom chain hoists are often used in assembly line operations, equipment maintenance, material handling, and other scenarios, significantly improving work efficiency and safety.

1. Compact design: Compared with traditional electric hoists, the ultra low headroom chain hoist has a thinner body, reducing the occupied space and making it suitable for installation in workshops with limited height.
2. Chain drive: It uses high-strength alloy steel chains, which are wear-resistant and have strong load-bearing capacity. The chains are closely arranged and operate smoothly.
3. Double-speed control: Some models support fast and slow speed adjustment, which is convenient for precise positioning and efficient handling.
4. Safety devices: Usually equipped with overload protection, limit switches and emergency braking functions to ensure operational safety.
1. Chain lubrication: Apply special lubricant regularly to reduce wear.
2. Check the fasteners: Ensure that the connecting components such as bolts and nuts are not loose and tighten them promptly if necessary.
3. Clean the body: Remove dust and debris to prevent interference with heat dissipation and operation.
4. Testing safety functions: Regularly verify the normal operation of overload protection and limit switches.
5. Professional maintenance: At least one comprehensive inspection should be conducted annually, and it should be carried out by professional technicians.
1. Chain jamming: This could be due to insufficient lubrication or chain deformation. It is necessary to clean and apply lubricating oil. In severe cases, the chain needs to be replaced.
2. Motor overheating: Check if it is overloaded or has poor ventilation. Reduce the load appropriately or improve the cooling conditions.
3. Abnormal noise: This might be caused by wear on the gears of the reducer. It is necessary to disassemble and inspect to replace the damaged components.
