Hyundai R35Z-9 Mini Excavator

Performance Capabilities and Applications

The R35Z-9 handles diverse compact excavation operations including urban utility trenching, residential foundation excavation, landscaping grading and shaping, confined space demolition, and material handling throughout Southern African urban construction sites. With standard 2,500 mm boom and 1,300 mm arm configuration, the versatile working range achieves 5,360 mm maximum digging reach, 5,240 mm maximum digging reach on ground, and 3,150 mm maximum digging depth, whilst maximum vertical wall digging depth reaches 2,190 mm. Optional 1,600 mm long arm extends maximum digging reach to 5,610 mm with 3,440 mm maximum digging depth.

The excavation performance delivers 3,200 kgf (31.4 kN) bucket digging force with standard 1,300 mm arm and 1,990 kgf (19.5 kN) arm digging force, managing compacted soils, rocky substrates, and challenging ground conditions. Maximum digging height reaches 4,830 mm whilst maximum dumping height achieves 3,450 mm with standard arm configuration, facilitating efficient material loading into trucks across confined construction sites.

The full hydrostatic travel system with two-speed axial piston motors delivers 4.5 km/h maximum travel speed in high range and 2.5 km/h in low range, whilst 30-degree maximum gradeability enables operation across sloped terrain. The 3.1-tonne maximum traction force provides reliable performance across varied ground conditions. Minimum swing radius measures 2,350 mm, enabling precise positioning in highly restricted urban environments typical of Southern African city construction projects.

The pilot pressure-operated joystick controls with detachable safety lever provide almost effortless and fatigue-less operation following ISO control patterns. The left-hand joystick controls swing and arm functions, whilst the right-hand joystick manages boom and bucket operations with integrated horn. Two traveling levers with pedals enable intuitive machine movement, whilst mechanical cable-type engine throttle allows precise engine speed control

Zero-Tail Swing Compact Performance for Southern African Urban Construction

Mini excavators with zero-tail swing design represent specialized compact earthmoving machines engineered for confined space excavation, urban utility installation, residential construction, and landscaping operations where minimal swing radius proves essential for safe and efficient operation. The Hyundai R35Z-9 generates 20.4 kW (27.3 HP) from its Yanmar 3TNV88 Tier 4 engine, managing 0.11 m³ bucket capacity for municipal infrastructure projects, residential construction, urban utility trenching, and landscaping operations. We supply the R35Z-9 to Southern African contractors with comprehensive technical support and genuine parts availability through our established regional service network.

This 3,650 kg mini excavator with zero-tail swing design excels in confined urban spaces requiring exceptional maneuverability and precise excavation control throughout the region.

Why Choose the Hyundai R35Z-9?

The Yanmar 3TNV88 Tier 4 certified engine delivers 27.3 HP (20.4 kW) gross power and 26.5 HP (19.8 kW) net power at 2,200 rpm with 10.9 kgf.m (79 lbf.ft) maximum torque at 1,100 rpm, providing robust performance for demanding compact excavation applications across Southern African construction sites. The water-cooled, four-cycle diesel engine with three cylinders in-line configuration features direct injection and low noise technology, ensuring reliable operation across varied regional conditions from coastal urban developments to inland infrastructure projects. The proven and reliable Tier 4 certified engine provides efficient fuel combustion and reduced noise levels, essential for urban construction environments throughout the region.
The advanced hydraulic system features variable displacement piston main pumps delivering 2 x 38.5 + 23.5 + 11.2 litres per minute, precision designed for fast operation with fine control capabilities. Optimized matching between the joystick and main control valve improves fine control and smoothness of operation, whilst the arm flow summation system provides energy savings, reduced cavitation, and increased speed. To improve safety and avoid boom drift, the R35Z-9 incorporates an integrated boom holding system. The hydraulic relief valve settings operate at 230 kgf/cm² for implement and travel circuits, 200 kgf/cm² for swing circuit, and 30 kgf/cm² for pilot circuit, ensuring responsive control across all excavation functions.
The zero-tail swing design proves particularly valuable for Southern African urban construction environments. The R35Z-9’s short tail swing radius allows operators to work in confined areas close to buildings, on roadways, and in urban areas where traditional excavators cannot operate safely. This compact radius design provides easy and efficient operation in any limited space work environment typical of densely developed urban areas throughout the region. The boom swing function enables the boom to offset left or right within 75-degree and 50-degree operating range respectively, designed for efficient work in congested residential and urban areas.

Technical Specifications

The Yanmar 3TNV88 powerplant comprises three cylinders with 88 mm bore and 90 mm stroke, displacing 1,642 cc. The water-cooled engine operates from a 42-litre fuel tank, supporting operational periods essential for urban Southern African construction locations.

The 3,650 kg operating weight with standard cabin configuration (3,500 kg with canopy) distributes across 300 mm wide rubber tracks as standard, providing 0.34 kgf/cm² ground pressure with cabin or 0.32 kgf/cm² with canopy. Optional 300 mm steel tracks accommodate demanding applications. The X-leg type center frame integrally welded with reinforced box-section pentagonal track frames provides exceptional strength and longer service life to withstand tough working conditions. The upper frame design absorbs high stress loads on the job.

The R35Z-9 reduces operating costs over time with extended component life including 250-hour bushing lubrication intervals, polymer shims for wear resistance and noise reduction, 1,000-hour hydraulic filter life, 5,000-hour hydraulic oil life, and efficient cooling systems. The ISO standard cabin meets international standards for TOPS, ROPS, and FOPS, ensuring operator safety. Standard equipment includes adjustable suspension seat with seat belt, radio/USB player, two front working lights, centralized monitoring with seven warning indicators, water temperature gauge, fuel gauge, and hour meter.
