16Ton Single Drum Roller Compactor WS166D Weichai Engine
The Qhmach WS166D 16-ton single drum roller compactor utilizes a powerful Weichai turbocharged engine and a hydrostatic drive system.
It is suitable for all construction sites, compacting loose surface materials such as sand and gravel, as well as surface compaction of crushed stone and ballast bases.
The WS166D hydraulic fully road roller compaction roller excels at construction sites such as highways, airports, dams, and industrial areas.
Main Technical Performance Characteristics

01. Efficient Power
The WS166D fully hydraulic single drum vibrating roller is equipped with a Weichai WP6 turbocharged engine with a power of 129kW, offering quick starting, durability, and fuel economy.

02. Intelligent Vibration Control
WS166D gravel roller compactor adopts an internationally renowned brand closed hydraulic vibration system, which consists of an electro-hydraulic controlled two-point variable pump and a fixed displacement motor to achieve dual-frequency and dual-amplitude vibration.The vibrating wheel adopts a reinforced inner partition structure with high support rigidity.

03. Advanced Drive System
Road Roller adopts the hydraulic drive system of internationally renowned brands and combines it with domestically renowned engineering drive axles to form an ideal drive transmission system. It is equipped with wet brakes and high-torque axle motors to adapt to the speed and traction requirements of various working conditions.

01. Easy Operation
Single-lever operation enhances safety and reduces labor intensity.
02. Durable Design
The WS166D single drum roller compactor vibratory wheel features a reinforced internal baffle structure for enhanced support rigidity. The impact-resistant, reinforced vibration bearing features four-point support, improving bearing load conditions. The carefully designed bearing seat with lubrication channels provides excellent lubrication and heat dissipation, ensuring superior performance and long-term reliability of the vibration bearing, even under severe alternating loads.

03. 25°(45%) Climbing Capability
The WS166D single drum vibrating roller, with its powerful engine and well-designed center of gravity, can effectively handle steep slopes and complex terrain, ensuring operational continuity and efficiency. At a 25° incline, the roller demonstrates excellent traction and stability, minimizing slippage and ensuring consistent compaction results.
04. Safe Brake System
Linked control of the non-powered brake ensures safety and reliability.

Convenient Maintenance
The engine cover at a wide angle for easy maintenance and servicing. This design allows operators to quickly access the engine components, streamlining routine checks and repairs. As a result, maintenance tasks can be completed efficiently, minimizing downtime and ensuring the roller remains in optimal working condition.
Qhmach - More Efficient Durable Safe Comfortable Road Roller
This single drum roller compactor is equipped with a cabin featuring heating and cooling air conditioning, ensuring high comfort for the operator. This system allows for efficient work in various weather conditions, reducing fatigue during long hours of operation.
