In water treatment plants, lifting equipment is often used for equipment maintenance, replacement, and installation. Unlike simple material handling, these tasks require accurate positioning and smooth operation, especially when handling pumps, motors, and other mechanical components.
A water treatment plant in Malaysia recently upgraded its lifting system by replacing traditional MD type double speed hoists with two European electric wire rope hoists supplied by Yuantai Crane. The new hoists were installed on the customer’s existing monorail overhead crane system to improve lifting control and enhance stability.

Customer Challenge
The customer is a water treatment plant in Malaysia. The facility uses overhead lifting equipment for regular maintenance work, including lifting pumps, motors, and other process equipment.
Before this upgrade, the customer used MD type double speed electric hoists. Although the existing hoists could complete basic lifting tasks, they found that the lifting accuracy was not ideal for some maintenance operations.
During equipment installation and replacement, operators needed better control when:
- Positioning heavy components
- Aligning equipment during installation
- Moving loads in limited working areas
For these applications, fast lifting alone is not enough. The hoist needs to provide smooth speed adjustment and accurate movement.
Therefore, the customer decided to upgrade the lifting equipment while keeping the existing crane structure.
Customized European Electric Wire Rope Hoist Solution
Based on the customer’s working requirements, Yuantai Crane supplied two sets of 4 ton NR model European electric wire rope hoists.

Instead of replacing the complete crane system, the customer only upgraded the hoisting units and continued using the existing monorail overhead crane. This helped reduce modification costs and shorten installation time.

The main specifications are:
- Lifting capacity: 4 tons
- Lifting height: 6 meters
- Lifting speed: 1.4/5 m/min
- Travel speed: 2-20 m/min
- Power supply: 415V/87Hz/3 phase
- Duty classification: M5
- Protection grade: IP54
- Control method: Pendant control + remote control
The configuration was selected to meet the customer’s requirements for reliable lifting performance and precise operation.
Key Features for Industrial Maintenance Applications
Dual Speed Lifting for Precise Load Positioning
The biggest improvement compared with the previous hoists is the better lifting control.
The new European electric hoists provide dual lifting speeds:
- Higher speed for normal lifting operations
- Lower speed for precise positioning
During maintenance work, operators can use the slow lifting speed to carefully adjust the load position. This is especially useful when installing pumps, motors, and other equipment that requires accurate alignment.

Variable Frequency Travel Control for Smooth Movement
The 4-ton NR hoists are equipped with variable frequency travel control.
Compared with traditional fixed-speed travel systems, VFD control allows:
- Smooth starting and stopping
- Reduced load swing
- More accurate positioning
- Lower impact on crane components
This is important in water treatment facilities because equipment is often installed around tanks, pipelines, and other structures where stable movement is required.

Efficient Upgrade Solution for Existing Crane Systems
Many industrial facilities already have overhead crane structures in operation but need improved lifting performance as production requirements increase.
Instead of replacing the complete crane system, upgrading the existing hoist is often a more practical choice. It reduces modification costs, minimizes installation time, and allows the plant to continue using its existing crane structure.

For this Malaysia water treatment plant, the customer upgraded only the lifting units while keeping the existing monorail crane system. The new wire rope hoists helped achieve:
- Better lifting accuracy for maintenance work
- Smoother load movement during operation
- Reduced impact on the existing crane structure
- Lower upgrade cost compared with a complete crane replacement
