Terex Utilities Expands Boom Lift Options for Power Substation Maintenance


Last month at the 2023 Utility Expo, Terex Utilities presented a pre-production Terex® Z-60 Substation Utility Boom (SUB) for the purpose of gathering market insights. The unit has been undergoing field tests throughout the year.

“This 6 ft-class insulated mobile elevated work platform (MEWP) is based on a Genie Z-60 FE and will be an expansion of our SUB product line, joining the Z-45 SUB, which was first introduced in 2021,” said Robert Hasegawa, product manager. “Since the Z-45 SUB’s successful launch, customers have expressed an interest in taller MEWPs, as well as hybrid options for use in substations.”

The Z-60 SUB 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 bucket truck. Featuring a fiberglass fly jib section and fiberglass platform with swing gate, the Z-60 SUB is built to the ANSI/SAIA 92.20 standard with the insulation complying to ANSI/SAIA 92.2. and an 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 226 kg, with a 2-person occupancy.

The Z-60 SUB is hybrid-powered, assisting utilities in their goal of achieving sustainable fleets. It has 2 modes of operation. In all-electric mode, the unit can work a full shift on a single battery charge. In hybrid mode, it has more than a week’s worth of run time with a single tank of diesel.

The Z-60 has an 5.68 m outside turning radius, 7.39 m up and over clearance, and working range that takes the platform 3 m below grade. Dual parallelogram and fully proportional controls enable precise positioning, which is further enhanced with a 1.5 m jib that has vertical rotation of 135°. Full-time active oscillating axle help maintain traction, while 45% gradeability and 33 cm ground clearance improve maneuverability in rough terrain.
