Kamaz 6520 6x4 Review: Engine, Performance and Payload

The Kamaz 6520 6x4 is a tough choice among heavy-duty commercial vehicles. It was engineered for difficult terrain, heavy payloads and long service life. Russian engineering provides it with endurance, while its payload capacity addresses the requirements of Indian construction, mining and infrastructure sectors. The review breaks down the engine, performance, payload and value of the truck.

Design and Build

The chassis is made with reinforced steel that provides strength to tolerate significant loads, while the axles, suspension and frame all work together to ensure a stable operation over bumpy surfaces. The cabin is mounted over the engine compartment providing visibility, a working control placement and ergonomic comfort for the driver. The geometry, robust bumpers and high ground clearance maximize safety and durability.

Engine and Powertrain

This commercial truck is powered by a Kamaz-740.63-400 engine that is a V8 diesel producing 400 hp and 1,255 Nm of torque (at 1,300–1,500 rpm) displacing 11.76 liters. The engine supplies good low-end power for loaded haulage and climbing grades.

The engine engages a ZF 16S/151 16 speed manual transmission that optimizes pulling power and fuel economy. The turbocharger and vehicle speed fuel injection system contribute to the efficiency of combustion. The firmness of the gear transition provides a seamless process for the driver, reducing fatigue and especially so for longer shifts.

Performance and Handling

The 6x4 transfer case delivers torque to both of the rear axles and provides even traction when travelling on unpaved ground. The front suspension is equipped with 12-leaf springs and double shock absorbers providing stability against the vehicle's weight as does the rear 13-leaf balanced leaf springs. 

Pneumatic drum type brakes provide a sure stop no matter if the vehicle is loaded or unloaded. The truck handles well for its application in mining pits, road construction and off-road hauling. Stability, traction and control contribute to the steady performance, and load performance is not in question.

Payload and Tipping Capability

With a gross vehicle weight of 33 100 kg and a payload weight of 20 150 kg, it is built for heavy duty use. The 25,600 kg-rated rear bogie is designed to ensure that the vehicle can carry significant loads without downgrading its ability.

The hydraulic tipper operates at a dumping angle of 50°, which facilitates speed unloading of sand, gravel or ore. The hydraulic system operates at a low energy level which reduces loading and unloading site dwell time thereby improving operating productivity.

Cabin Comfort and Ergonomics

The upper cabin is spacious with functional ergonomics. Adjustable seating, easy to read instrumentation and control inputs reduce fatigue. Noise insulation attenuates noise from the engine. While there is no sleeper berth in the truck, it is geared for daily truck site haulage.

Fuel Efficiency

The fuel tank holds 350 liters with a cruise speed of up to 60 km/h. The fuel efficiency is rated at 36.5 L/100 km, meaning that you will be able to cover long operating distances. By improving fuel economy, idle time and downtime while refilling fuel stops will be eliminated, which is a vital consideration for operating at remote sites.

Market Positioning and Price

The price of the truck varies from ₹32.05 lakh to ₹35 lakh based on configuration. Against domestic and international competition, it promises high torque, hard-wearing build and reliability in operation at competitive price. Increased acceptance of Russian tipper trucks by Indian operators shows confidence in Kamaz vehicles.

Conclusion

The Kamaz 6520 6x4 tipper truck is robust, reliable and highly efficient to operate. Its engine, suspension and hydraulic systems all combine to handle heavy payloads and provide driver control. Nothing luxurious, the truck is robust and performance-oriented. Contractors and fleet owners looking for reliable vehicles for mining, construction and bulk material movement find Kamaz 6520 6x4 an excellent option.
