ISUZU GIGA 6x4 Flatbed Rollback Tow Truck 15 Tons Heavy-Duty Road Rescue Vehicle

Product Introduction

A wrecker, sometimes referred to as a recovery or tow truck, is built on a truck chassis and kitted out with full hydraulic lifting and pulling hardware. That includes a boom, dual winches, an under‑lift assembly and stabilizer outriggers.

Its main job is to get crashed, broken‑down or illegally parked vehicles off the roadway to restore normal traffic flow. It’s one single unit that handles many different roadside recovery scenarios.

The 6x4 layout is where real heavy recovery starts. A 4x2 wrecker tops out around 8 to 12 tons of towing before the front axle lifts and the brakes fade. This GIGA 6x4, with a 9-ton front and twin 13-ton rear axles under 35,000 kg GVW, drags up to 34,000 kg — It can handle tough jobs: hauling a loaded semi‑tractor, recovering a rolled‑over bus, or pulling out a stuck excavator.

This machine works very differently from a flatbed rollback. Rollback models load cars and light‑duty trucks onto their flat platform. By contrast, this heavy‑duty wrecker uses its lifting mechanism to tow large heavy vehicles that are too big to sit on a deck.

If you compare it with similar‑capacity wreckers built on HOWO and Dongfeng chassis, the ISUZU GIGA does come with a higher initial purchase price.

Even so, there are clear advantages to make up for that extra cost. It holds its resale value far better, suffers fewer unplanned breakdowns, and features a well‑proven powertrain. Plenty of fleet operators running Japanese‑spec units have clocked well over 800 000 kilometres with this driveline still performing reliably.

We build the hydraulic upper body in our own plant on a genuine ISUZU GIGA VC66 chassis. Italian multi-way valves, Rexroth-technology cylinders, imported seals. Boom type, towing tonnage, winch brand, steering side, paint and decals are all locked in the PI before steel is cut.

Technical Specifications

The standard heavy build runs an ISUZU 6WG1-TCG60, inline six, 15.681 liters, 309 kW / 420 HP, with 2250 N.m of torque on tap from 900 to 1300 rpm. That is exactly the band where you drag a 30-ton load up a slippery on-ramp. FAST 12-speed gearbox, 12 forward and 2 reverse, with a QH50 flange. Clutch is a 430mm diaphragm. Fuel tank 400 liters. Air brakes with ABS, 24V electrics, 165Ah battery.

This wrecker adopts the reliable Isuzu GIGA VC66 chassis, featuring a 4600+1370mm wheelbase setup. It is equipped with a 9-ton front axle and dual 13-ton rear axles, paired with 12R22.5 tires — ten standard tires plus one spare tire are included in the full set. The truck boasts a 35-ton gross vehicle weight and a 21.5-ton empty weight, with a maximum traveling speed of 100km/h. Its passability is solid too, with a 23° approach angle and 18° departure angle for complex road conditions.

The professional upper working device is the core of this recovery truck’s performance. The hexagonal boom delivers a powerful 20-ton lifting capacity, supports full 360° rotation, and reaches a maximum lifting height of 6500mm. It is fitted with two independent 10-ton hydraulic winches, every winch matched with 40 meters of 18mm steel wire rope. The under-lift device can bear 16 tons of static load, and maintains stable working performance with an 8-ton load when fully extended.

To guarantee operational stability during heavy rescue tasks, two hydraulic outriggers are installed, each with a bearing capacity of 80kN. For flexible and safe operation, we configure both manual control valves on the right-side operating platform and a wireless remote controller, allowing operators to work remotely and stay away from dangerous construction areas.

Applications

Highway rescue — clearing rolled or broken-down heavy trucks and buses on expressways, often under time pressure and poor lighting.

Fleet & depot recovery — yard-to-yard recovery for logistics fleets, bus depots, and construction companies that need their own first-response rig.

Municipal traffic control — towing illegally parked or abandoned vehicles off city streets, with under-lift arms that do not damage the towed vehicle's driveline.

Moving construction machinery

Great for relocating excavators, loaders and road rollers that get bogged down, moving them from one work‑site to another. This comes in handy when a lowboy trailer isn’t a viable option on‑site.

Crash and roll‑over recovery work

You can straighten out heavy vehicles that have tipped over and haul damaged wrecks off the road. This is exactly where the 360‑degree swing boom and pair of winches really prove their worth on tough jobs.

Product Line

Three builds cover most export demand. The 300HP 6HK1 integrated wrecker is the budget pick, 20-ton towing, Euro 5, popular where rules are loose and roads are rough. The 420HP 6WG1 rotator is the default heavy unit — 34-ton towing, 360-degree boom, the one most highway patrols and fleet operators actually buy. The 460HP 6WG1 flatbed with knuckle crane suits buyers who need to both carry and lift, common in depots that handle mixed vehicles. LHD is standard; RHD is available for Indonesia, Malaysia, Pakistan, Kenya and other right-hand markets. Not sure which build fits your routes?
