TOST Tow cable retractor with guillotine
The simple way to safe and economical aero tows

   
Reel                                                 Tail Piece with Guillotine
In 1992 TOST acquired the rights to manufacture and market the Feurstein system.
This proven system has been installed over 300 times in the past 10 years.
The equipment has been completely reworked and is now available in traditional TOST quality.

The tow cable retractor with guillotine (CRG) provides a number of important advantages:
Increased flight safety and lower costs through elimination of the cable drop curve
Considerably diminished noise levels for residents near airfields, since aircraft needs less engine power during decent and can land directly
No cable drop with potential risk to persons or aircraft
Reduced fuel consumption through shorter flight and taxi time
No delays in aircraft starts because of tracing and retrieving tow cables
Longer tow cable life because of reduced ground contact and contamination
Low weight of system (approx. 8 kg including tow cable)
Low maintenance thanks to simple construction
Cable retraction monitored visually and electrically
Only minor (reversible) modifications to aircraft necessary for mounting

The tow retractor with guillotine has the following components:
Retraction winch
Cable traction unit with integrated stop plate and guillotine
Electric switch unit

Options:
Towing release support  with Bowden cable
Allows the use also of tow rope without the Reel system but with E-85 Release
(Shown below)$807.60
E-85 TOST Towing Release option for Retractor System $385.00
Special Release Lever for installing E-85 to CGR or support $89.80
Special Cable drum (larger) for 60 Meter Cable $110.00
Standard Towing Cable 60 Meter length for TOST Reel System $119.00
Towing Cable for CRG 6.1mmx 250Meter length $284.00

The retraction winch is mounted on a base plate which is attached to the fuselage of the towing aircraft behind the seat. This equipment can be dismounted, if necessary, in approx. 30 minutes. The main components are a 12VDC motor (standard) with a slip clutch, motor bracket, cable drum and cable cover. The tow rope passes through or under the fuselage to the cable stop plate in an aluminum cable duct.
The new traction unit with integrated stop plate and guillotine is bolted to the existing towing frame. The guillotine is activated by the existing release cable.
The cable load is taken up by the stop plate via a sleeve crimped to the towing cable. Towing may start only after the sleeve has come firmly to rest against the stop plate.
The towing cable is 6mm in diameter and has a standard length of 50 meters. The cable is terminated by an aluminum endpiece, complete with weak link and ring pair (specify breaking load of weak link when ordering).
Once the glider has been released, the electric switch unit starts the retracting winch. Operation can be checked in the rearview mirror. After the cable has been fully rewound - red marking on the end of the cable is visible - the motor switches off automatically.
