Road construction demands more than just speed—it requires uncompromising quality. When traditional rollers experience slippage or surface tearing during operation, the consequences extend beyond delayed timelines to significant financial losses. The Sakai TZ702 Tire Roller addresses these challenges with superior engineering that ensures reliable pavement compaction.
Advanced Drive System for Superior Performance
The TZ702 features an innovative dual-engine rear-wheel drive design that achieves hydrostatic differential effects. This technology prevents sublayer deformation and tearing while maintaining consistent traction across varying terrain. The result is uniform compaction density without surface damage from wheel slippage—a critical advantage for projects requiring precision.
Operator-Centric Visibility and Control
Optimized visibility forms the cornerstone of the TZ702's design philosophy. Operators enjoy unobstructed views of all tire surfaces and water spray patterns, enabling real-time adjustments for optimal compaction. This human-machine interface enhances both productivity and quality assurance throughout the construction process.
Durable Water Spray System
Engineered for longevity, the roller's 4,000-liter polyethylene water tank features fully rust-proof construction. Complemented by corrosion-resistant spray bars and metal nozzles, the system eliminates clogging risks while ensuring even moisture distribution—a prerequisite for achieving ideal compaction conditions.
Comprehensive Safety Features
The TZ702 prioritizes worksite safety through multiple redundant braking systems:
-
Hydraulic foot-activated brakes on all four rear wheels
-
Spring-applied hydraulic parking brakes
-
Standard mechanical foot brake for emergency situations
Low-Maintenance Hydraulic Steering
By utilizing hydraulic drive motors for steering, the TZ702 eliminates conventional adjustment points and reduces maintenance requirements for components like universal joints, gears, and chains. This streamlined approach lowers operational costs while enhancing equipment reliability.
Versatile Compaction Solutions
The roller's mirror-finish pressure spray system and hydraulic spray system allow contractors to select the ideal application method for different pavement materials. This adaptability ensures optimal compaction results across diverse project specifications.
Through its combination of technological innovation and practical design, the Sakai TZ702 establishes new benchmarks for performance and dependability in road construction equipment.
