Performance |

New Big Clamshell Bucket
A new big 1.55 m3 clamshell bucket, 19% greater than ever, can be equipped on a new telescopic arm whose bucket pull-up force is increased greatly. This clamshell bucket employs a roller-support type sliding mechanism to reduce the load to clamshell cylinders for higher durability. This allows for deeper, more productive digging. The clamshell bucket also has an ejector function for swift dumping onto a truck. Its bucket jolt-reducing device can speed up positioning in underground work and during dumping on a truck.
High Versatility
This machine, featuring 30 m digging depth, is designed to reduce operating weight and ground pressure, suited especially for job sites whose load-bearing capacity and work space are limited. The base machine is a versatile ZX330LC-5G that provides proven fuel efficiency, operator comfort, maintainability and durability. Consumables are readily available too.
Quicker Arm Extension
A mix of the new telescopic arm and hydraulic system dramatically increases arm extension speed and pull-up ability. What’s more, the big 1.55 m3 bucket helps increase production |
Relentless Pursuit of Safety |
 |
Sliding Cab - Sliding stroke distance: 1 300 mm
The sliding cab, on this telescopic arm excavator, projects forward, 960 mm more over a Hitachi standard model. This speciality design gives the operator better downward visibility from the operator seat, boosting efficiency with confidence. The cab can still slide a further 1 300 mm, totaling 2 260 mm, to give unobstructed view. To enhance safety, the cab can be locked in position with a switch, avoiding inadvertent movements. A walkway and handrail are provided for easy access to the cab
Large Cab-Floor Window
A large integral cabfloor window, made of polycarbonate, offers good downward see-through visibility to deep excavation underground. This makes it easier to position and excavate using the telescopic arm, boosting job efficiency and safety
Reduced Cab Vibration for Operator Comfort
Less cab vibration helps improve operator comfort. The cab sliding mechanism is redesigned from roller type to slide-plate type to increase contact areas for less vibration and shocks
Array of Safety Devices
To enhance safety, the machine is provided with an array of safety devices, including warning lights and safety alarm. Even if one of the twin ropes breaks or extends excessively, warning lights turn on and a safety alarm sounds to alert the operator to such a failure. The bucket landing alarm device also buzzers when the bucket lands at a target point for alerting
Arm Cylinder Stroke End Limit Device
At the cylinder stroke end, a limit device works to absorb shocks when loading a dump truck for safe, smooth operation
Twin-Rope Lines
The twin-rope lines are adopted for safety. Even if one of the twin ropes breaks, the other can hold the telescopic arm in position. To evenly distribute the load to twin roles in normal operation, an equalizer is provided to extend rope life.
Free-Fall Prevention Devices
Holding Valve: Even if piping or hose punctures, a combination of the telescopic arm cylinder and a holding valve on the boom cylinder can hold the clamshell to avoid its free fall.
Free-Fall Prevention Device: The clamshell is operated by twin-rope lines for its pull-up operations. Even if one of twin ropes breaks, the other can hold the clamshell to avoid its free fall
Miscellaneous Safety Accessories
- Bucket jolt-reducing device
- Bucket landing alarm device
- Leveler
- Operation warning lights
- Operator guard against falling prevention |

Durable, Simplified Engine
This engine has a track record showing impressive durability at countless tough job sites around the world. The engine - associated with a rugged design, a direct fuel injection system and an elaborate governor - goes green, and complies with EU Stage II and US EPA Tier 2 emissions regulations |
Simplified Maintenance |
 |
|
The long service life is ensured by using larger-diameter sheaves on the telescopic arm to reduce its bending force. To this end, sheaves and wire ropes are newly attached on the outside. This configuration is convenient for checking if the telescopic arm extends and retracts normally in daily maintenance
Extended Rope Life
Rope replacement intervals: 1 800 hours
Note: Rope replacement intervals vary according to operating conditions. |
 |
Dust-Proof Indoor Net
An air condenser and radiator can be serviced with ease. For the air condenser, a dust-proof indoor net can readily be removed from its front for easy cleaning with compressed air. Also, it is openable at its rear for cleaning. For the radiator, air blowing can readily be done at its rear through a onetouch open cover
