Description
The HPD-T and HPD-HV Fairmont Sign Post Drivers
are heavy-duty, hydraulically powered reciprocating
tools designed for driving various types of sign posts
into the ground. The high power-to-weight ratio
and low vibration reduce operator fatigue and
increase productivity.
These drivers have a lifting bracket and two side
handles for easy positioning.
The HPD-HV has a remote double-acting operating
valve that allows operation on either open-center or
closed-center hydraulic systems.
