Ideal for moderate raises

The HST, a squeeze-type tamper, is ideal for switch tamping at moderate raises. Highly productive, the HST is known throughout the industry for its traversing workheads, performance speeds, simplicity in operation and maintenance, as well its high degree of dependability. In addition, the smaller footprint allows the HST to work in much tighter areas than other tampers.

Robust workheads/tamping tools system

The 16 Tool HST includes four workheads operating at 3200 VPM in tamping power. While the workhead carriages are normally configured to work simultaneously, each side can be operated independently if the conditions require it.
