The Terex Hi-Ranger TM Series Celebrates 20 Years at The Utility Expo

The Terex Hi-Ranger TM Series of heavy-duty aerial devices for transmission applications was first introduced to the utility industry at the 2003 ICUEE Show (now Utility Expo). Now 20 years later, Terex plans to showcase the TM100 in our live equipment demonstrations at the 2023 Utility Expo held in Louisville, KY September 26 through September 28. 

The Hi-Ranger TM has a long history of innovative design and dependable performance. The mid-range model has remained a perennial favorite among utility crews working to build, replace and maintain transmission lines. Utility crews appreciate the rigid, stable design, and smooth operation, especially when using dual functions to get into the work zone. 

This classic non-overcenter aerial features upper and lower fiberglass inserts, upper and lower boom extension, and continuous unrestricted planetary rotation. Boom articulation of 78˚ of elevation above horizontal, 168° of upper boom articulation, and 90° of lower boom articulation helps line workers accurately position themselves close to the work.  

Three models are available with working heights of 87, 100, and 125 feet, respectively. These units can be mounted on track or truck carriers. Adding a platform access step inside the bed of the truck eliminates the need to lower the bucket to the ground from the lower controls. TM models are available with an end mount boom tip configuration, and a horizontal side reach of up to 52 feet (on the TM100) with 800 pounds of platform capacity.  

TM aerial devices are Category “C” rated, with the option for Category “A” or “B” rating per ANSI A92.2 and is commonly used up to 500 kv but has been rated up to 765 kv for specialty applications.
