Standard
Steel Carriage
The
Carriage or “sled” is approximately 4 feet wide
by 12 feet long, and weighs approximately 1800 pounds (820kg).
It has a maximum payload capacity of 5,000 pounds (2,270 kg).
The
top of the carriage is flat, and the sides are unobstructed
at least 2 inches below the top-mounting plane.
The
top plate has a pattern of tapped ½-inch mounting holes
located on 3-inch centers. A carriage top plate with metric
hole sizing and spacing may be selected, if desired. Additional
mounting holes are placed on the sides and rear of the frame.
Two brake systems are included in the standard HYGETM. The first
system (Primary) is a brake that is energized prior to firing
and remains on during the firing. The second standard system
is an emergency brake system mounted on the carriage that is
actuated by a cam switch farther down the track. If the first
system fails or has not been energized, the second system will
trip and stop the sled before the end of the rail system.
All
brake zones are provided with ports for mounting pressure transducers
and isolation valves between Zones
The
carriage pneumatic brakes operate on the rails through brake
shoes. The maximum drag force from the carriage is at least
12,000 pounds (5,450 kg).
Options
- Roller
assembly to raise the sled off the slider pads to allow
easier return of the sled to its firing position.
- A
third braking system ( second Tank) for use as delay braking.
This allows sled to be fired with out Primary brake being
applied, for pulses requiring for faster rise time of pulse
leading edge. Like the emergency brake system it is actuated
by a separate cam switch down the track before the emergency
ramp and operated at lower pressure for a more gradual stopping
of sled
- Mount
pressure transducers on Brake Zones
