The Z-60 Substation Utility Boom (SUB) concept vehicle from Terex Utilities, Watertown, S.D., is designed for substation work and other applications where an insulated device is needed, and an articulating z-boom is a more effective option than a bucket truck. Featuring a fiberglass fly jib section and fiberglass platform with swing gate, the vehicle complies with ANSI A92.2 standard for Category E insulating rating of 20 kV. The standard fiberglass platform comes with floor grating and optional cutouts for increased visibility and water egress. The platform capacity is 500 lbs. with a two-person occupancy. The unit is hybrid-powered and will be used to assess the market need through a series of field tests throughout the year, the company says.
