ZW220

Product catalog summary
Introduction
The ZW220 Wheel Loader is part of the new-generation 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 ZW220 offers three work modes to boost production and reduce fuel consumption, along with three driving modes for optimal speed shifting. 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 design. It offers enhanced upward and rear visibility, ergonomically positioned controls, and a suspension seat designed for comfort.
Durability
The ZW220 is built with robust differential gears, a durable drive system, and variable displacement pumps. It includes a hydraulically operated cooling fan with a heat-sensing system, a large hydraulic oil cooler, and a protected fuel tank.
Maintenance
Maintenance is simplified with extended hydraulic oil replacement intervals, conveniently located filters, and an easy-to-read monitor. The machine features a flat cab floor, a hinged radiator cover, and a dirt-less front frame.
Safety
Safety features include a full fan guard, an optional emergency steering system, mis-operation protection, and a reliable dual-line brake system.
Environmental Considerations
The ZW220 complies with U.S EPA Tier 3 and EU Stage III A emission regulations and features a low noise design that meets EU noise regulation 2000/14/EC, Stage II.
Specifications
The wheel loader has an operating weight of 17,010 - 17,560 kg, a bucket capacity of 2.7-3.4 m3, and a maximum engine output of 164 kW (220 HP).
HN Bushings
HN bushings reduce grease consumption and extend lubrication intervals from 100 to 500 hours, enhancing durability. They contain high-viscosity oil vacuum impregnated in sintered high-hardness metal, providing lubrication during operation.
Safety-First Design
The machine includes safety features like mis-operation protection, retractable seat belts, an inclined ladder, and a full fan guard. An optional emergency steering system ensures steering capability even if the engine fails. The ROPS/FOPS cab protects the operator, conforming to ISO standards.
Environmentally Friendly Design
The machine features a common rail type fuel injection system that complies with emission regulations, reducing particulate matter and fuel consumption. The cooled EGR system lowers combustion temperature, reducing NOx emissions. Approximately 85% of the machine is recyclable, with lead-free components and biodegradable hydraulic oil available.
Engine Specifications
The engine is an Isuzu AH-6HK1, a 4-cycle water-cooled, direct injection type with a turbocharger and intercooler. It delivers a maximum power of 164 kW (220 HP) at 2000 rpm. Features include a hydraulically operated cooling fan, environmentally friendly oil drain, and a quick-release fuel filter.
Power Train
The power train includes a torque converter and a countershaft type powershift transmission with automatic and manual shift features. The drive system is a four-wheel drive with semi-floating axles and a heavy-duty planetary final drive.
Hydraulic System
The hydraulic system features independent control levers for the arm and bucket, with a variable displacement axial plunger pump and fixed displacement type gear pump. It includes a full-flow 15-micron return filter and offers hydraulic cycle times for lift arm raise, lower, and bucket dump.
Service Refill Capacities
Key refill capacities include a 270 L fuel tank, 38 L engine coolant, 25 L engine oil, and 114 L hydraulic oil tank.
Operator's Station
The operator's station is equipped with a ROPS/FOPS cab, adjustable armrest, bi-level auto air conditioner, and a high-back seat with multiple adjustments. It includes a retractable seat belt, large tray, drink holder, and ergonomic handrails.
Loader Linkage and Attachments
The Z-bar loader linkage provides high bucket breakout force. A full line of Hitachi buckets and attachments is available, including general-purpose and rock buckets with bolt-on teeth or cutting edges.
Optional Equipment
Optional equipment includes high-capacity batteries, additional counterweights, biodegradable hydraulic oil, and an emergency steering system. Availability may vary by country.
Specifications Overview
This document provides detailed specifications for a wheel loader model KL-EN022 by Hitachi Construction Machinery Co., Ltd. The specifications include various performance metrics and dimensions based on ISO standards.
Key Specifications
  • Dumping Clearance: Ranges from 2,780 mm to 3,420 mm at a 45-degree angle and full height.
  • Reach: At a 45-degree dump and full height, the reach varies between 1,120 mm and 1,230 mm.
  • Digging Depth: Horizontal digging angle depth ranges from 100 mm to 180 mm.
  • Static Tipping Load: Straight tipping load ranges from 128 kN (13,050 kgf) to 134 kN (13,700 kgf), while full 40-degree turn tipping load ranges from 91 kN (9,250 kgf) to 116 kN (11,850 kgf).
  • Breakout Force: Varies between 150 kN (15,350 kgf) and 178 kN (18,120 kgf).
  • Operating Weight: Ranges from 17,010 kg to 17,560 kg.
Standards and Notes
  • All dimensions, weight, and performance data are based on ISO 6746-1:1987, ISO 7137:1997, and ISO 7546:1983.
  • Static tipping load and operating weight include 23.5-25-16PR (L3) tires, lubricants, a full fuel tank, and an operator.
  • Machine stability and operating weight depend on counterweight, tire size, and other attachments.
Additional Information
The document includes a bucket selection guide and notes that specifications are subject to change without notice. Illustrations may show standard models with optional equipment. Users are advised to read the Operator’s Manual for proper operation.
