Hydraulic Rail Stressor 24.70

•
The obstructionless hydraulic rail
stressor is used primarily during
the welding of rails
•
The stressor serves to pull, push
or hold the rail in neutral length
during welding processes
•
As a result of the obstructionless
design, rail vehicles can pass over
when the stressor is mounted on
the rails

•
Yokes in box-type design and lightweight
metal hydraulic cylinders make possible
a maximum weight of the heaviest
component of only 33 kg
•
Quick mounting without tools
•
The yokes can also be arranged above
the rail, e.g. on a ballastless track
•
The option of parallel operation on both
rails of the track is possible

•
2 yokes with 2 clamping device
•
2 hydraulic cylinders
•
2 pulling device
•
1 hydraulic pump. According to order either
a hydraulic hand pump or a hydraulic power
pack with pipings and hose couplings
•
Two-stage pump with automatic
switching from low-pressure
(quick feed) to high-pressure
mode
•
Drive by 4-stroke petrol engine
•
Compact unit with two-stage pump;
automatic switching from low-
pressure (quick feed) to high-
pressure mode
The device consists of the following items: Hydraulic Hand Pump Hydraulic Power Pack
