Introduction
This tow bar UTOWE170-C-4 was designed based on over 30 years of Hydro
experience in manufacturing tow bars. The design focus of this new product was
to combine an outstanding level of operator safety with meeting today’s
requirements for highly competitive ground support equipment.
The following safety features of the UTOWE170-C-4 are described below:
Ball Lock Pin ensures against
accidental or unexpected opening
of tow head when in use .
Flow-Valve between pump and
hydraulic cylinder which minimizes
the speed of retraction of the
undercarriage (no drops!)
Dampening tow-eye using
Urethane spring
