Underground Puller – U7500

Underground Puller – U7500


The Sherman + Reilly Revolution Series U7500 is a bullwheel puller for the installation of underground distribution conductor. The single platform, modular design provides 7,500 lbs. pulling capacity offering plenty of power to handle most installations. The hydraulically driven twin capstan bullwheels ensure smooth, well-controlled pulls.

Powered by a 35 hp 4-cylinder diesel engine, the transmission has two forward speeds and a reverse demand payout. The U7500 has plenty of power as well as flexibility to deal with varying needs during an underground pull. A joystick-controlled, hydraulically positioned extendable boom with 170° of swing arc is available for reaching into and pulling from pad-mounted transformers and other tight openings.

With state of the art design to ensure operator safety, the U7500 features a Safe Zone Cab™. This enclosure is designed to keep an operator off the ground while the equipment is in use. Built with a fully adjustable, ergonomic seat and a digital touch display for all machine operations, diagnostics, and pull status. The Safe Zone™ Cab is designed to reduce operator fatigue thereby reducing errors and injuries in the field.

Equipped with a digital electronic load recorder for documenting pulling tensions and an electronic footage counter providing accurate, and continuous measurement of conductor/cable deployed. Optional on-board air compressor.
