Product Advantages and Selling Point

1. High Lifting Capacity for Real-World Loads

The MQH37A container side loader is engineered to handle up to 40 tons, making it suitable for:

• Fully loaded 20ft ISO containers

• Standard 40ft containers

• Containers with dense or heavy cargo

The lifting system maintains smooth motion even under near-capacity loads, reducing container sway and improving operational safety.

2. Integrated Side Lifting System

Unlike conventional container trailers, this side loader semi trailer features dual hydraulic cranes mounted on the trailer chassis. These cranes allow operators to:

• Load containers directly from the ground

• Unload containers at customer sites

• Stack or reposition containers within yards

This self-loading capability significantly reduces dependency on forklifts, gantry cranes, or reach stackers.

3. Reinforced Chassis Structure

ZW Group designs the MQH37A frame using high-strength steel with optimized cross-member spacing. Key benefits include:

• Improved torsional resistance during lifting

• Reduced fatigue over long-term use

• Enhanced durability on rough or uneven roads

Critical stress areas such as crane mounting zones, axle connections, and kingpin sections are reinforced to extend service life.

4. Stable 3 Axle Configuration

The 3 axle design provides:

• Better weight distribution

• Improved braking performance

• Enhanced stability during highway transport

• Compliance with common axle load limits

This configuration is especially important when transporting heavy containers over long distances.

5. Reliable Hydraulic System

The hydraulic system is designed for continuous operation in high-temperature and dusty environments. Features include:

• High-quality hydraulic cylinders

• Stable pressure control valves

• Efficient oil circulation layout

• Easy-access maintenance points

Operators benefit from precise lifting control and reduced downtime.

6. Operator-Friendly Control System

The control layout is intuitive and easy to learn, allowing operators to quickly master:

• Lifting and lowering movements

• Container positioning

• Emergency stop procedures

This reduces training time and improves site safety.

7. Adaptability to Different Markets

The MQH37A container side loader semi trailer can be customized according to:

• Local road regulations

• Container handling standards

• Preferred axle brands

• Suspension types (mechanical or air)

• Tire specifications

This flexibility makes it suitable for a wide range of international projects.
