Notch-type connector 096000
This two-part connector consists of a hook and an oval ring. The oval ring has a notch on one long side which allows it to be slotted into the hook. The ring's oval shape ensures that it is aligned automatically in the direction of pull.
An exact fit and true shape guarantee safe towing.
Chemically nickel-plated parts, load capacity 1500 daN without deformation, compact design, mass only 116 g. Connect using a 8 mm shackle (112800).
Oval ring (096005) and hook (096010) can be ordered separately.

Connecting ring pair 102000
All Tost releases must be operated only with this ring pair meeting the aeronautical standard LN 65091. Connecting ring pairs are vital for the safe connection and reliable separation of tow cable and tow release. Damaged or deformed ring pairs can impair correct functioning.
Ring pairs should be visually checked at regular intervals and replaced if necessary.
Rings are stamped TOST and LN 65091. Mass: 73 g..

Scissor-type connector 097000
One-piece, very light connector, chemically nickel-plated, load capacity 1500 daN (when closed), mass only 73 g. Connect to
winch launch cable using a special 12 mm shackle (112312) and simply clip onto the parachute shackle.

Cable Recovery Parachute Systems

 

 
 
 
 

A good cable parachute significantly extends the life of your tow cable.
Operating conditions for cable parachutes vary greatly and depend on the airstrip size and layout, terrain, wind conditions and winch performance. To allow for various conditions we offer two different parachute types.

BT cable parachute   133000
Large and stable parachute, cable can be rewound at low speed. Tapes from the parachute canopy gathered in a semicircular ring, 8 mm diameter, use 8 mm connecting shackle.
Grappling lines gathered in delta-type connector (095010), direct attachment possible (screw fastening).
Parachute available in two colours, red and mauve, for quickly telling leeward and windward cables apart. Use 3 m safety cable and 10 m connecting cable.

Cross-panel cable parachute   133500
Light-weight parachute combines high strength with a very good price/performance ratio. Thanks to the special design, the parachute descends very slowly and almost without rotating or swinging. Cable can be rewound at low speed. Connection to leather thimbles, thickness 25 mm.
Use 3 m safety cable, a connecting cable is not needed.

Refer to the table for further technical details.

Maintenance
Untangle harness if necessary so that the parachute can open properly.
Every parachute should be washed after extended use or heavy soiling. Use a mild detergent. Hang the parachute to dry, but not in direct sunlight or near a hot stove.

Proper care prolongs the Iife of your parachute.

 

 
 
 

Safety cable   121003
Reduces the danger of cable hangup when overrunning the cable.
Description: steel cable with rubber sheath; Tost uses and recommends a red cable for faster cable location and retrieval. The connecting ring pair is fitted on the aircraft side, the weak links must be connected on the winch cable side (see diagram on page 24).

Connecting cables   121007/121007
The length of the connecting cable depends on the diameter of the parachute canopy.
For parachutes with canopy diameters less than 1500 mm, the minimum required distance between the release of the glider and the parachute vent is 5 m. Use a 2 m connecting cable, 121002.
For parachutes with canopy diameters between 1500 and 2000 mm, the minimum required distance between the release of the glider and the parachute vent is 13 m. Use a 10 m connecting cable, 121007.
Description: steel cable with rubber sheath, a red colour is recommended as for the safety cable, with a thimble at each end.
Note: a stiffening rubber sheath is not stipulated for the connecting cable, but is highly recommended.

Connecting sequence
· Safety cable with connecting ring pair, length 3 m
· Weak link, select breaking load according to aircraft type certification
· Connecting cable, length 10 m (only for cable parachutes with a canopy diameter greater than 1500 mm (eg, BT cable parachute)

Round thimble for safety cable
and connecting cable   222550

Jerky winch starts tend to deform the thimbles on the cable preamble causing damage to the cable. The new round thimble effectively prevents deformation. lt has a 6.5 mm bore for connection of an 8 mm shackle, outside diameter 24 mm, groove 5 mm.
