Product catalog summary

Overview
The ZAXIS-7 series ZX135USL-7 is a forestry excavator engineered for high performance, emphasizing efficiency and durability. It is equipped with a robust engine, advanced hydraulic systems, and a reinforced structure to withstand demanding environments.

Engine Specifications
The excavator is powered by a TOYOTA INDUSTRIES CORPORATION 1KDE engine, producing 74 kW (ISO 14396) and 73 kW (ISO 9249) at 2000 min-1. It features a turbocharged, intercooled system with cooled EGR and aftertreatment via DOC and CSF systems. The engine delivers a maximum torque of 390 Nm at 1700 min-1 and has a piston displacement of 2.982 L.

Hydraulic System
The hydraulic system includes two variable displacement axial piston pumps with a maximum oil flow of 2 x 117 L/min and a pilot pump with 33.6 L/min. It features relief valve settings for various circuits to ensure optimal performance and safety.

Upperstructure and Undercarriage
The upperstructure is designed with a D-section frame for enhanced deformation resistance, while the undercarriage features a high track-type design with welded track frames and lubricated components. The travel device includes a 2-speed axial piston motor and automatic transmission system.

Sound Levels
The cab sound level is 69 dB(A) according to ISO 6396:2008, and the external sound level is 99 dB(A) as per ISO 6395:2008 and EU Directive 2000/14/EC.

Service Refill Capacities
Key capacities include a 200 L fuel tank, 18.7 L engine coolant, 19.1 L engine oil, and 155 L hydraulic system capacity.

Weights and Dimensions
The operating weight ranges from 15,900 to 16,900 kg, with configurations affecting ground pressure. The dimensions are optimized for stability and maneuverability in forestry applications.

Lifting Capacities
Lifting capacities are specified for different arm lengths and configurations, adhering to ISO 10567 standards, ensuring they do not exceed 75% of the tipping load or 87% of full hydraulic capacity.

Additional Features
The excavator includes features such as an auto idle system, ECO/PWR mode control, and a comprehensive monitor system with multiple alarms and displays. The cab is designed for operator comfort with sound suppression, air conditioning, and safety features like ROPS compliance.
