The firm says that these are specially equipped to offer improved performance and safety in the tough demolition application.
The firm says that its ZX390TC-7 tool-carrier model has been specially adapted to work with larger working tools, and can be used for secondary demolition works. There are two multicarrier models, the ZX400MC-7 and ZX600MC-7, which are supplied with up to four front attachments and are built to meet the requirements of all demolition projects. They can complete the tasks of several machines onsite, which reduces the need for transport and personnel costs. The ruggedised machines are also said to improve performance and safety for operators.
The machines are based on standard Hitachi Zaxis-7 models and feature Zaxis-7 technology and Stage V-compliant engines. The excavators have been developed for the demolition working cycle in partnership with specialist firm Kenki Technology Group (KTEG).
The cabs feature extra protection to ensure maximum safety for the operator, with metal guards over the windscreen for example. Special booms and sticks are fitted and able to cope with the high shocks generated by hydraulic attachments while protection is fitted to the excavator’s components to minimise the risk of damage. The two-piece boom system allows the user to change the excavator’s configuration to best suit the working application. The system is said to allow quick changes, with a choice of front ends for long reach or excavating duties. This system means that one excavator can be used instead of multiple machines, increasing utilisation and reducing equipment rental costs for demolition firms.
The hydraulics are modified to ensure that there is sufficient power for a range of demolition attachments. The machines also have cooling systems configured to cope with the high dust levels encountered in the demolition environment.
