Hitachi unveils excavator focused on underground construction
Hitachi's telescopic arm excavator, which offers depths of up to 21m, was developed to tackle challenging underground construction projects
Japanese multinational Hitachi has unveiled an excavator with a telescopic arm that can reach depths of up to 21m.
The arm on Hitachi's ZX210LC-6 excavator extends and retracts using a combination of ropes and hydraulic cylinders, allowing it rapidly to shift soil.
ZX210LC-6 is the smallest model in Hitachi's fleet of similar-sized excavators, rendering it a good fit for urban construction jobs where space limitation is an issue.
The machine's sliding cab is positioned 960mm higher up than regular excavator models, and it can be pushed up an extra 1,300mm to improve visibility for the driver.
Hitachi said its new excavator offers enhanced safety features as well. For instance, if the two ropes snap or extend too far, a warning light will immediately alert the operator. A warning buzzer can also be heard if too much pressure is applied when the clamshell bucket is on the ground.
Moreover, the telescopic arm of the excavator has a hose rupture valve, which prevents any further damage to the machine if the cylinders malfunction or are damaged.
The machine was engineered in-house, according to Toru Nabeshima, the manager of the special application department at Hitachi Construction Machinery (Europe).
Nebeshima added that the ZX210LC-6 was "developed to meet the demands of a specific industry application" and was "ideal for complex below-ground excavation tasks".
