BRIEF

The 50T Rotator Tow Truck Superstructure is a heavy-duty recovery system engineered for the most demanding vehicle recovery, accident clearance, and heavy-lift operations. Designed to be mounted on a 6×4 or 8×4 heavy-duty chassis, this superstructure combines a powerful rotator boom, a high-capacity underlift, dual winches, and a robust outrigger system into a single integrated recovery solution. Whether recovering overturned semi-trailers, clearing multi-vehicle accidents, or removing stuck heavy equipment from off-road sites, this system delivers the power, reach, and precision required to get the job done safely and efficiently. Its dual-function design – combining crane-like lifting capabilities with tow-truck underlift functions – makes it one of the most versatile recovery systems available in its class.

The superstructure features a 3-section telescopic boom with a maximum lifting height of 13,129 mm and a maximum working radius of 10,710 mm, enabling operators to reach across wide accident scenes and access vehicles in difficult positions. At a 45° angle, the boom delivers a lifting capacity of 50,000 kg when fully retracted and 11,500 kg when fully extended – providing the strength needed to right overturned trucks and lift heavy loads. Complementing the boom is the underlift system, which offers a maximum lifting capacity of 28,000 kg and a towing weight of 36,000 kg. With a telescopic stroke of 1,750 mm and a folding angle range of -10° to 92°, the underlift can be positioned precisely beneath disabled vehicles for quick and secure towing, even in tight spaces.

The system is equipped with dual winches, each rated at 25,000 kg pulling force, delivering a combined 50-tonne pulling capacity – enough to drag fully laden trucks out of ditches or up steep recovery ramps. Each winch carries 55 metres of 26mm diameter wire rope, providing extended reach for complex recoveries. To ensure absolute stability during lifting and winching operations, the outrigger system features a lower-mounted H-type front outrigger with a lateral span of 6,600 mm and an L-type rear outrigger with a lateral span of 4,080 mm, with a longitudinal span of 5,550 mm between front and rear outriggers. This wide stance keeps the recovery truck planted firmly on the ground, even during heavy side-lifts or off-centre pulls. The combination of powerful winches, a versatile boom, a rugged underlift, and a stable outrigger base makes this rotator tow truck superstructure a comprehensive recovery solution for the toughest roadside and off-road challenges.

FEATURES

1. Underlift System – Heavy-Duty Towing and Lifting

• 28,000 kg maximum lifting capacity – Handles the heaviest disabled vehicles with ease, including fully loaded trucks and buses.
• 7,310 kg lifting capacity even when fully extended – Maintains useful lifting power at maximum reach, ensuring versatility in tight recovery scenarios.
• 1,750 mm telescopic stroke – Allows the underlift to extend and retract smoothly for precise positioning beneath damaged vehicles.
• Folding angle range of -10° to 92° – Enables the underlift to reach below ground level for ditch recoveries or angle up for steep approaches.
• 1,735 mm maximum ground clearance of the fully extended fork – Lifts disabled vehicles high enough for wheel changes or dolly placement without additional equipment.
• 36,000 kg towing weight – Allows the recovery truck to tow heavily loaded vehicles safely over long distances.
• 3,410 mm maximum effective length – Reaches under long-wheelbase vehicles and provides secure lifting points for various chassis configurations.

2. Boom System – Powerful Lifting and Reach

• 50,000 kg lifting capacity at 45° (boom retracted) – Provides the raw power needed to right overturned heavy trucks and lift extreme loads.
• 11,500 kg lifting capacity at 45° (boom fully extended) – Maintains strong lifting performance even at maximum reach, ensuring versatility in complex recovery scenarios.
• 13,129 mm maximum lifting height – Reaches high positions for overhead lifting, building access, or recovering vehicles from elevated areas.
• 10,710 mm maximum working radius – Covers wide accident scenes without repositioning the recovery truck, saving time and improving safety.
• Three-section telescopic boom – Extends smoothly and progressively for precise load positioning without sudden jerks.
• Luffing angle range of 0° to 62° – Allows the boom to be raised to various angles for optimal lifting positions, from low-level pulls to high-angle recoveries.
• 5,880 mm basic boom length – Provides a solid foundation for lifting operations, with ample room for telescopic extension.

3. Winch System – Dual Pulling Power

• Dual winches, each rated at 25,000 kg – Deliver a combined 50-tonne pulling capacity, allowing straight-line pulls, multi-anchor recoveries, or using one winch at a time for lighter jobs.
• 55-meter wire rope per winch (26 mm diameter) – Long cable length allows the recovery truck to stay on stable ground while reaching vehicles far down embankments or across medians.
• 5 m/min winch speed – Provides controlled, steady pulling power for safe and precise recoveries without sudden jerks or cable snap risks.
• Independent winch operation – Each winch can be operated separately, enabling complex rigging configurations for angled or multi-point recoveries.

---

4. Outrigger System – Unmatched Stability

• Lower-mounted H-type front outrigger – Provides excellent lateral stability with a wide stance of 6,600 mm, distributing the recovery truck’s weight evenly during heavy lifts.
• L-type rear outrigger – Offers robust support at the rear with a lateral span of 4,080 mm, preventing tipping during winching and lifting operations.
• 5,550 mm longitudinal span between front and rear outriggers – Creates a long, stable base that resists forward, rearward, and side tipping, ensuring the recovery truck remains planted even during off-centre lifts.
• Sturdy outrigger construction – Built to withstand the extreme forces generated by 50-tonne lifting and 50-tonne pulling operations, maintaining structural integrity under the heaviest loads.
• Quick deployment – Outriggers can be extended and retracted rapidly to minimise setup time and get to work faster.

5. Integrated System Performance – A Complete Recovery Solution

• Boom and underlift work in tandem – Allows operators to lift, rotate, and tow in a single continuous operation, reducing recovery time and eliminating the need for multiple support vehicles.
• Non-continuous slewing – Slewing is controlled based on actual working conditions, ensuring safe, controlled rotation of heavy loads without over-stressing the system.
• Versatile application range – Suitable for highway accident clearance, off-road recovery, heavy equipment relocation, construction site support, and disaster response.
• Dual-purpose design – Functions as both a crane for heavy lifting and a tow truck for vehicle recovery, replacing two separate pieces of equipment.
• Built for extreme conditions – Designed to perform reliably in harsh environments, including extreme heat, cold, rain, and dusty job sites.

6. Safety and Durability – Built to Last

• Hydraulic overload protection – Prevents the system from exceeding its rated capacities, protecting both the equipment and the operator.
• Load-holding valves on all cylinders – Prevent boom, underlift, or outrigger drift if hydraulic pressure drops, locking loads securely in place.
• Heavy-duty steel construction – The boom, underlift, and outriggers are fabricated from high-strength steel, ensuring long service life even under extreme loads.
• Corrosion-resistant coating – All components are treated with anti-corrosive paints to protect against rust, road salt, and environmental exposure, extending service life and maintaining resale value.
• Fail-safe design – Even in the event of operator error, the system prevents unsafe manoeuvres, protecting both personnel and equipment.
