ZW series - Wheel Loaders

Product catalog summary

Introduction
The ZW220 Wheel Loader is part of the ZW Series, designed for high production and mobility. It features advanced technologies for engine and pump torque control, three work modes, and three driving modes to enhance operation and productivity.

Productivity
The loader offers three work modes for production and fuel efficiency, and three driving modes for speed optimization. It includes an automatic transmission with a load-sensing system, a high-torque engine, and a large torque converter. Optional features include a limited slip differential and a ride control system.

Comfort and Visibility
The cab is designed for comfort with a panoramic view, bi-level auto air conditioning, and low noise. Ergonomically positioned controls and an optional multi-functional joystick enhance usability.

Durability
Durability is enhanced with robust differential gears, a durable drive system, and a hydraulically operated cooling fan. The loader has a strong frame and protected fuel tank, with components designed for longevity.

Maintenance
Maintenance is simplified with extended hydraulic oil replacement intervals, conveniently located filters, and an easy-to-read monitor. It includes a large tool box and a flat cab floor for easy cleaning.

Safety
Safety features include a full fan guard, optional emergency steering system, and a reliable dual-line brake system. The cab is ROPS/FOPS certified for operator protection.

Environmental Considerations
The loader complies with U.S EPA Tier 3 and EU Stage III A emission regulations and features a low noise engine. It is designed to be recyclable.

Specifications
The ZW220 has an operating weight of 17,390 kg, a bucket capacity of 2.7-3.4 m3, and a maximum engine output of 164 kW (223 PS).

Engine and Maintenance Features
The machine features easy access to the engine oil drain port and air conditioning filters. HN bushings reduce grease consumption and extend lubrication intervals.

Safety Features
Safety mechanisms include mis-operation protection, a retractable seat belt, an inclined ladder, and a full fan guard. An optional emergency steering system ensures steering functionality if the engine fails. The cab is ROPS/FOPS certified.

Environmental and Noise Reduction
The machine features a common rail type fuel injection system that complies with emission regulations. The cooled EGR system reduces fuel consumption and emissions. Noise reduction is achieved through a strengthened cylinder block, a Hitachi Silent fan, and a muffler.

Engine Specifications
The engine model is Isuzu AH-6HK1X, delivering a maximum power of 164 kW (220 HP) at 2000 rpm. It features a two-element dry type air cleaner with a restriction indicator.

Power Train and Transmission
The machine uses a torque converter, countershaft type powershift transmission with automatic and manual shift features. It has a four-wheel drive system with semi-floating axles and a dual-line hydraulic brake system.

Hydraulic System
The hydraulic system includes independent control levers for the arm and bucket, with a variable displacement axial plunger pump and a fixed displacement type gear pump.

Service Refill Capacities
Service refill capacities include 285 liters for the fuel tank, 38 liters for engine coolant, and 114 liters for the hydraulic oil tank.

Operator's Station and Additional Features
The operator's station includes a ROPS/FOPS cab with noise and vibration reduction features, an adjustable seat, and a comprehensive electrical system with various indicators and alarms.

Specifications Overview
Key measurements include a width over tires of 2,785 mm, a wheelbase of 3,300 mm, and a ground clearance of 450 mm. The bucket width is 2,910 mm, and the turning radius is 5,620 mm.

Performance Metrics
The static tipping load varies between 131 kN to 137 kN, with a full 40-degree turn load ranging from 113 kN to 119 kN. The breakout force is between 150 kN and 178 kN. The operating weight ranges from 17,250 kg to 17,800 kg.

Standards and Notes
All dimensions and performance data are based on ISO standards. The static tipping load and operating weight include specific tire configurations and assume no ballast, with lubricants, a full fuel tank, and an operator.

Bucket Selection Guide
The document includes a bucket selection guide with various configurations and angles for optimal performance.

Additional Information
Specifications are subject to change without notice, and illustrations may not include all optional equipment. Users are advised to read the Operator’s Manual for proper operation.
