Sany SSR120 Roller Traveling System GP

The Sany SSR120 Roller Traveling System GP is the complete propulsion and mobility assembly that enables the Sany SSR120 single-drum vibratory roller to move efficiently across job sites, including the hydrostatic drive motors, wheel reducers, axle assemblies, and braking components. This robust traveling system provides reliable traction and precise speed control for both transport and compaction operations. As a trusted supplier of Sany Parts, we provide complete traveling system GP assemblies and individual components that meet exact OEM specifications. Each system is tested to ensure smooth operation and reliable braking performance.

What is the Sany SSR120 Roller Traveling System GP?

The Sany SSR120 Roller Traveling System GP is the complete drive train assembly that converts hydraulic power from the propulsion pump into mechanical motion, enabling the roller to travel across job sites and perform compaction passes.

This system consists of two hydrostatic drive motors mounted on the rear axle, each driving a planetary wheel reducer that provides the necessary torque multiplication for climbing grades and traversing soft ground conditions. the Sany SSR120 Roller Traveling System GP also includes the rear axle assembly with differential gearing, service brakes, parking brake mechanism, and the wheel mounting hubs that secure the rubber tires.

The hydrostatic drive motors in the Sany SSR120 Roller Traveling System GP are variable-displacement axial piston units that receive pressurized hydraulic oil from the main propulsion pump and convert it into rotational mechanical energy. These motors feature a two-speed displacement control that provides high torque at low speed for compaction operations and higher speed at reduced torque for job site transport. The motor displacement is automatically adjusted by the machine control system based on travel speed requirements and load conditions, optimizing efficiency and preventing engine stall during heavy pulling. The motors incorporate integral flushing valves that circulate cool oil through the motor cases to maintain acceptable operating temperatures during extended high-load operation.

The planetary wheel reducers in the Sany SSR120 Roller Traveling System GP provide the final torque multiplication stage between the drive motors and the wheels. Each reducer consists of a sun gear driven by the hydraulic motor output shaft, multiple planet gears rotating within a ring gear, and a planet carrier connected to the wheel hub.

This planetary gear arrangement provides high torque capacity in a compact envelope while distributing loads across multiple gear teeth for extended service life. The reducers are filled with heavy-duty gear oil and sealed with double-lip oil seals that prevent lubricant leakage and contaminant ingress.

As a replacement assembly for the Sany SSR120 roller, the Sany SSR120 Roller Traveling System GP is supplied as a complete unit with drive motors, wheel reducers, axle assembly, brakes, and wheel hubs pre-assembled and tested. Each system undergoes comprehensive testing including drive motor performance verification, wheel reducer gear mesh checking, brake function testing, and leak integrity validation.

The drive motors are calibrated to match the propulsion pump characteristics, and the wheel reducer gear sets are matched for proper contact patterns. The standardized mounting interfaces and hose connections ensure compatibility with the existing machine frame and hydraulic plumbing.

What are the Routine Maintenance Considerations for the Sany SSR120 Roller Traveling System GP?

Regular inspection and oil level verification of the Sany SSR120 Roller Traveling System GP planetary wheel reducers is essential for maintaining reliable propulsion performance. Technicians should check the gear oil level in each wheel reducer at the recommended intervals, adding the specified gear oil grade as needed to maintain proper lubrication.

The oil should be replaced at scheduled intervals to remove wear particles and degraded lubricant that could accelerate gear and bearing wear. The condition of the drained oil should be observed for metallic particles, water contamination, or unusual discoloration that could indicate developing internal problems.

Brake system inspection and adjustment are critical safety maintenance tasks for the Sany SSR120 Roller Traveling System GP. The service brake pads should be checked for wear at scheduled intervals and replaced when they reach the minimum thickness specification. The brake disc surfaces should be inspected for scoring, cracking, or excessive wear that could reduce braking effectiveness.

The brake hydraulic system should be checked for proper fluid level and any signs of leakage at hoses, fittings, or wheel cylinders. The parking brake mechanism should be tested for proper engagement and holding force, with adjustments made as necessary to maintain specified braking performance. The brake pedal free play and travel should be verified against specifications to ensure responsive brake application.

Visual inspection of the Sany SSR120 Roller Traveling System GP drive motors and wheel hubs should be conducted as part of daily pre-operation checks. Technicians should examine the drive motor housings for signs of hydraulic oil leakage at shaft seals, port connections, and case drain fittings. The wheel hub seals should be checked for gear oil leakage that could indicate seal damage or excessive bearing wear.

Any oil leaks should be investigated and repaired promptly to prevent lubricant loss and potential component damage. The drive motor mounting bolts should be checked for proper torque to prevent movement that could cause coupling misalignment and accelerated wear. The wheel lug nuts should be verified for correct torque to ensure safe wheel retention.

Periodic wheel bearing inspection and adjustment are important for maintaining the Sany SSR120 Roller Traveling System GP performance and tire life. The wheel hub bearings should be checked for proper preload at scheduled intervals, with adjustment made as necessary to eliminate excessive free play that could cause tire wear and steering instability.

The bearings should be inspected for signs of pitting, spalling, or discoloration during scheduled maintenance, and replaced if any damage is found. The wheel alignment should be verified periodically to ensure proper toe-in and camber settings that minimize tire wear and maintain straight-line tracking. The tires should be inspected for proper inflation pressure, tread wear patterns, and sidewall damage.
