Application Fields

The Rear Tipping Semi-Trailer is the go-to solution for industries requiring efficient bulk material transport. Its rear-discharge mechanism enables rapid unloading in confined spaces where other tipping methods cannot operate safely.

Mining Operations

Rear tipping trailers are extensively used in mines and quarries for transporting coal, ore, overburden, and tailings. The rear-tipping design allows for quick unloading at processing plants or stockpiles, significantly reducing cycle times. They are typically used in conjunction with excavators and loaders for loading operations.

Construction & Infrastructure

On construction sites, rear tippers handle sand, gravel, crushed stone, asphalt, concrete debris, and demolition waste. The ability to unload precisely where needed – without extensive maneuvering – makes them invaluable for foundation work, road building, and earthmoving projects.

Bulk Material Logistics

Rear tippers are ideal for transporting coal, aggregates, and other bulk commodities from mines or quarries to processing facilities, power plants, or ports. Their high unloading efficiency translates directly into reduced operational time and increased productivity.

Agriculture

In agricultural applications, rear tippers handle grain, fertilizer, feed, and other bulk agricultural products. The rear-discharge mechanism enables rapid unloading at storage facilities or processing plants.

Waste Management

Rear tippers are also used in waste management for transporting construction and demolition waste, providing efficient unloading at recycling facilities or landfills.

Rear tipping semi-trailers are widely used in construction, mining, and agriculture for transporting aggregates, sand, gravel, and demolition debris.

Key Advantages

Rapid Unloading – Maximized Efficiency

The rear-tipping mechanism enables complete unloading in minutes. This dramatically reduces cycle times and increases operational efficiency compared to manual unloading methods.

Less Space Required

Unlike side-tipping trailers that require wide, open spaces for unloading, rear tippers can operate in tight, restricted areas – they only need the unloading area to be flat and clear of obstructions. This makes them ideal for urban construction sites and confined job sites.

High-Strength Construction

Built with T700/T750 high-strength steel and reinforced frame construction, our rear tippers are engineered to withstand the extreme loads and impact of bulk material handling. The cargo box is constructed with high-tensile steel, delivering high strength, strong lifting force, good rigidity and toughness, and strong bearing capacity.

Automatic Tilting & Unloading

The hydraulic system enables automatic tilting and unloading controlled entirely from the cab. The driver never needs to leave the vehicle during unloading – saving time and labor while improving safety.

Versatile Cargo Box Options

Available in both dustpan and rectangular configurations, the cargo box can be tailored to specific material handling requirements.

Reliable Hydraulic System

The front-mounted telescopic hydraulic system, featuring premium cylinders and optimized hydraulic design, ensures smooth and safe unloading. The system includes automatic locking valves to prevent accidental lowering.

Premium Components

We equip every rear tipper with world-class components – FUWA/HT axles, WABCO brake systems, and optional HYVA cylinders – ensuring reliable performance and easy parts availability worldwide.

Proven Durability

Every trailer undergoes sandblasting for surface preparation, followed by one coat of anti-corrosion primer and two finish coats – ensuring long-lasting protection against rust and corrosion in demanding environments.

5. How to Use – Operating Guide

Safe and efficient operation of a rear tipping semi-trailer requires following proper procedures. Proper training and adherence to safety protocols can significantly reduce tipping accidents.

Pre-Operation Checks

Before each use, conduct a thorough inspection:

• Hydraulic System – Check oil level and inspect for leaks; ensure hydraulic oil is clean and within recommended specifications
• Tires – Check tire pressure and inspect for damage or abnormal wear
• Lights – Ensure all lights, including brake and tail lights, are functioning
• Brakes – Test brake performance
• Fasteners – Ensure all bolts and fasteners are secure
• Safety Features – Ensure all safety features are functioning properly
• Rear Door – Ensure the rear door locking mechanism is operational

Loading Procedure

• Position the trailer on level ground before loading
• Ensure the load is evenly distributed – both front-to-back and side-to-side
• Do not overload – adhere to the trailer‘s rated payload capacity
• Avoid loading cargo too far forward, as this can over-stress the hydraulic system

Unloading (Tipping) Procedure

Step-by-step operation:

• Open the rear door – Release the rear door locking mechanism before tipping
• Position the vehicle – Ensure the trailer is on level, stable ground
• Engage PTO – Place transmission in neutral, engage the clutch for 5 seconds, engage the PTO
• Select low gear – Shift into a low gear (4th gear or below)
• Activate lift – Move the pneumatic control valve handle to the “raise” position
• *Begin lifting – Release the clutch – the trailer will begin to tip
• Control engine speed – Engine RPM should be kept below 1,500 RPM
• Monitor the tip – Ensure material flows evenly from the rear
• Full extension – When the cylinder reaches full travel, move the control valve to the “neutral” position

Lowering Procedure

Step-by-step lowering:

• Engage the clutch for 5 seconds
• Disengage the PTO
• Disengage the transmission gear
• Release the clutch
• Slowly move the pneumatic control valve from neutral to the “lower” position
• Control lowering speed – The valve is proportional; move it slowly for controlled descent
• Wait 30 seconds after the body is fully lowered before moving the valve back to neutral

Critical Safety Rules

• Never tip on a slope – Only tip on level ground
• Never move the vehicle while tipping – Moving during tipping creates instantaneous high pressure in the hydraulic system
• Never exceed 1,500 RPM during tipping operations
• Never use the hydraulic cylinder as a stable support for the body – it is for tipping only
• Do not leave the cylinder exposed for more than 2 hours (or 30 minutes in humid conditions) – this can cause oxidation and corrosion
• Never adjust the relief valve – This removes critical safety protection

Maintenance & Care

Regular maintenance is critical for rear tipping trailers as it directly impacts performance, safety, and longevity. Routine inspections help ensure all components function properly, extending the trailer‘s lifespan and reducing overall costs.

Hydraulic System Maintenance

The hydraulic system is the most critical component of a rear tipper. Up to 50% of operational failures can be attributed to hydraulic system issues. Follow these guidelines:
