The Hydraulic Switch Tamper (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.
The Production Tamper (Jackson 6700), a squeeze-type tamper, is ideal for switch/production tamping at moderate raises, with the ability to make raises up to four inches in any type ballast. Highly productive, the 6700 can handle rates of 22 ties per minute using single insertions and a one- to two-inch raise in clean, free-flowing ballast.
The Production Tamper (Mark IV), a squeeze-type tamper, includes four workhead carriages, each containing two hydraulic vibrator tamping units, which in turn each have two abrasion-resistant tamping tools attached to the underside of the vibrator mount. These hydraulic vibrators deliver a robust 3000 VPM in tamping power, with a positive displacement of 3/8 inches.
