Please note the following for the use of the hose safety catch in an environment subject to risk of
fire or explosion:
The hose safety catch components are made of metallic material. Die risk of sparking is very low,
but generally given.
A minimum spacing between hoses under pressure is still required when using the hose safety
catch, because the length of the catch wire is designed so that pressure can be released in case of
damage (see description of function).
Recommended minimum separation: 0,5m
Installation/Assembly
The hose safety catch consists of many single parts, which are fitted together on the hose by
technicians to form the safety device.
Make sure before starting assembly that the hose system is not under pressure. Observe the
following assembly instructions.
Assembly instructions
•
Select the correct fixing elements.
•
Position the wire guide on the hose with the hose clamp.
•
Set the spacing to 45 mm between hose clamp and the end of the ferrule [Fig. 1]. If the
fitting has an elbow, you must also take the position of the wire guide to the pipe bend into
account [Fig. 2].
•
Tighten the bolt on the clamp until the rubber insert (elastomer profile) is secure on the
hose, but still allows the hose to swell according to the permissible operating pressure.
•
Lay the catch wire on the hose [Fig. 3]. Take the ends of the wire and lead them under the
hose so that the wires cross. This forms a loop [Fig. 4]. Then insert the ends of the wire
through the large hole in the wire guide. This produces another crossing point [Fig. 5].
•
Before fitting the standard fixing bracket on a DKO connection, you must insert the ends of
the wire into the slot [Fig. 6]. Using the two-piece version, the assembly can be done
afterwards [Fig. 7]. The torques of the fixing bolts is 6,0Nm for thread M5 and 10,0Nm for
M6 thread.
•
After the assembly of the bracket, secure the catch wire with a Velcro band to the ferrule
[Fig. 8].
•
The assembly to a hose with a SAE flange is analogous to a DKO fitting [Fig. 9].
When using fittings from other suppliers, you need to assure that the free distance between end of
nut and the counterpart is big enough for the fixing plate. The plate may not be jammed to ensure
the sealing of the hydraulic fitting.
