Product Specifications

Technical details and manufacturing context for Wheeled Excavator

Definition
A wheeled excavator is a self-propelled construction equipment vehicle mounted on rubber tires, featuring a rotating cab, hydraulic boom, arm, and bucket system. It combines the digging capabilities of traditional excavators with the mobility and speed of wheeled vehicles, making it ideal for urban construction sites, road projects, and applications requiring frequent relocation between job sites. The machine is powered by a diesel engine that drives hydraulic pumps, which control the boom, arm, and bucket movements for digging and loading, while separate hydraulic systems manage the wheel drive and steering for mobility. The operator controls all functions from an enclosed cab using joysticks and pedals. Typical specifications for this class of machine include an operating weight of 12–22 tons, engine power of 90–160 kW (ISO 9249), bucket capacity of 0.4–1.0 m³ (ISO 7451), maximum digging depth of 4.5–6.5 m (ISO 6015), travel speed of 20–35 km/h (ISO 6014), operating pressure of 30–35 MPa, swing speed of 8–12 r/min, max digging reach of 7.5–9.5 m (ISO 6015), tire specification of 10.00-20–12.00-24 (ISO 4250), minimum ground clearance of 350–450 mm, fuel tank capacity of 200–350 L, and noise level of 100–110 dB(A) (ISO 6395). These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The machine is constructed with high-strength steel and rubber components. Always confirm model-specific values and standards with the manufacturer before procurement or operation.
Working Principle
The wheeled excavator operates through a diesel engine that powers hydraulic pumps, which in turn drive hydraulic cylinders and motors. These control the boom, arm, and bucket movements for digging and loading, while separate hydraulic systems manage the wheel drive and steering for mobility. The operator controls all functions from an enclosed cab using joysticks and pedals.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Hydraulic cylinder seal failure
Cause: Contamination ingress from external debris or degraded hydraulic fluid, leading to abrasive wear and loss of sealing integrity
Undercarriage track link and bushing wear
Cause: High cyclic loading combined with abrasive soil particles causing accelerated surface degradation and loss of dimensional tolerance
Maintenance Indicators
  • Unusual metallic grinding or knocking sounds from the swing bearing during rotation
  • Visible hydraulic fluid leaks at cylinder rod seals or hose connections under pressure
Engineering Tips
  • Implement proactive hydraulic fluid analysis every 250 operating hours to detect contamination and chemical degradation before component damage occurs
  • Establish regular undercarriage cleaning and inspection protocols after operation in abrasive environments, with precise track tension adjustments to minimize uneven wear patterns
