Simplex A Series Mechanical Track Jacks

Simplex A Series Mechanical Track Jacks

The “A” series track jacks provide fast, safe track lifting for surfacing, lining, changing tie plates and many other track maintenance procedures.

  • All track jacks are designed to operate safely with a minimum amount of handle effort.
  • The quick-trip mechanism allows track jacks to be instantly tripped while under load. (Just engage the lifting pawl in the retaining pawl, and complete a down-stroke of the lining bar.)
  • The “A” series track jacks incorporate a rust proof tension spring which maintains full engagement of the jack's lifting and retaining pawls, so that dependable operation is assured.
  • All mechanical track jacks have square sockets designed for use with 38.1mm square x 1676.4mm long standard railroad lining bars (Model No. A17B).

IMPORTANT: Track jacks are not designed for controlled lowering due to their trip feature.
