Hitachi ZX 22 U-2 overview

Hitachi ZX 22 U-2 features overview

Improved Visibility with Roof Sun Visor (Canopy)
The sun visor, an integral part of the roof, gives better upward visibility. Overhang canopy keeps operator's knees dry in light rain.

Standard equipment may vary from country to country, so please contact your Hitachi dealer for details.
OPTIONAL EQUIPMENT
Optional equipment may vary by country, so please consult your Hitachi dealer for details.

These specifi cations can be changed without prior notice. Illustrations and photos show the standard models, and may also include optional equipment, accessories as well as all standard equipment with some differences in colour and features. Before use read out the operator's manual for proper operation and understand them

Engine / Driveline and transmission

Two Travel Speeds Provided
Two different travel speeds are available, making transporting the machine through the jobsite more efficient and smoother.
Pilot-Control Shut-Off Lever
All operations in front, swing, drive and blade can be switched off by locking the pilot control shut-off valve. This effectively prevents accidental lever control.
Neutral Engine Start System
The engine can only start when the pilot control shut-off lever is locked, this is called the neutral engine starting system. This eliminates unexpected lurching when the engine suddenly starts if it touches the control lever unconsciously.
Swing/Travel Parking Brakes (Standard)
The swing parking brake and travel parking brake are both standard for improved safety.
Split-Type Front Hoses
The split front hoses are connected to the machine cover ports and back of the boom for easy replacement. Swing motor Control valve Alternator Starter engine Pilot filter Muffler Engine Fuel filter Fuel tank Hyd oil tank Battery Reserve tank Oil cooler Radiator Engine oil supply Water separator Air cleaner The ZX22U-2 shares the same equipment layout for an easy, efficient inspection and replacement. Inspection points focus on fast daily maintenance.
HYDRAULIC SYSTEM
Pilot type hydraulic control lever, pilot control shut-off lever, two speed travel system, swing parking brake, travel park brake, piping for attachments.

Tyres / Tracks

Rubber Mounted Floor
The cab rests on 4 shock-absorbing rubber mounts to ensure comfortable operation.
Tilt-Up Floor
The cab floor can be tilted upward for easy, quick maintenance even in case of an emergency. Ground can be tilted up to 50 so the operator can work under the cabin floor. It also provides direct access to the swing mechanism and starter motor behind the engine below the cab floor. This design reduces inspection and servicing time.
Simplified Daily Maintenance
The engine cover can slide up and down even in tight spaces for quick maintenance. No more swing open cover that hinders maintenance and maintenance work.
Uses Tracks Promoting Easy Mud Removal
The X-Beam track frame is smooth for mud removal. One side slope on the side track frame encourages mud slipping and minimises dirt packing problem. This reduces machine washing time and also reduces disposal costs.
Easy to Repair Steel Cover
A steel cover is used for tough operation, which allows easy repairs in case of damage. The steel cover is durable, recyclable and economical.
