The HB640S handles diverse construction operations including municipal infrastructure development, building site preparation, utility trench excavation, and material loading applications throughout Southern Africa. The loader section achieves 8,793 kgf shovel breakout force and 5,642 kgf loader arm breakout force with 2,000 kgf payload capacity, whilst the backhoe section reaches 4.77 metres maximum dig depth with standard dipper or 5.83 metres with optional telescopic dipper, accommodating various excavation requirements.
The automatic power shift transmission delivers three forward speeds and three reverse speeds optimized for construction site operations. First gear provides precise control for excavation and loading operations. Second gear supports general excavating and loading sequences. Third gear achieves 38.8 km/h forward travel speed for efficient site-to-site movement, with reverse maximum 20.3 km/h. The gear selector allows straightforward selection between forward, neutral, and reverse directions.
The machine operates effectively with 480 mm minimum ground clearance, 2,220 mm wheelbase providing a stable platform, and standard four-wheel drive system improving mobility across challenging terrain conditions. The loader section achieves 2.96 metres dump height and 3.39 metres load-over height with 1.26 m³ standard bucket capacity. Optional 6-in-1 multi-purpose bucket with 1.1 m³ capacity provides additional versatility for specialized applications. The backhoe offers 201-degree bucket rotation with square-cut bucket configuration.
Advanced performance systems include optional Adjustable Flow Control System (AFCS) optimizing travel power when transiting on highways, and optional Smooth Ride Control (SRC) system reducing cycle times whilst improving productivity and fuel efficiency. The SRC system minimizes loader lift bounce when travelling over rough terrain, reducing material spillage and improving travel with a full bucket.
Backhoe loaders are multi-functional construction machines combining front-end loading capabilities with rear-mounted excavation systems, designed for diverse earthmoving, trenching, and material handling operations across construction sites. The Hyundai HB640S delivers 100 HP gross power from its Perkins 1104D-44TA Tier 3 engine, managing 1.26 m³ loader bucket capacity and 0.22 m³ backhoe bucket capacity for municipal infrastructure projects, building construction, and utility installations. We supply the HB640S to Southern African contractors with comprehensive parts support and technical service through our established dealer network.
This 8,500 kg backhoe loader excels in varied applications across construction sites requiring both loading and precision excavation capabilities throughout the region.
The Perkins 1104D-44TA powerplant comprises four cylinders with turbocharged and intercooled aspiration, displacing 4.4 litres. The water-cooled engine operates from a 145-litre fuel tank, supporting extended operational periods between refuelling stops essential for remote Southern African construction locations.
The 8,500 kg standard operating weight transfers across 12.5/80×18-12PR front tyres and 16.9×28-12PR rear tyres as standard specification. Optional tyre configurations include 400x70_20-16PR front tyres for enhanced traction, or 19.5LX24-12PR rear tyres for specialized applications, accommodating varied ground conditions throughout the region.
The hydraulic system features 120-litre total capacity with 100-litre refill capacity in the main tank. Regular maintenance benefits from straightforward tilt-up hood providing ground-level access to the engine compartment, filters, and grease points. Visible hydraulic oil sight gauge mounted on the tank side enables convenient inspection. Oil-immersed wet disc brakes with individual actuation provide reliable stopping performance, featuring self-adjusting design for extended service life.
