5.6 Examples for possible defects of hoses
- Damages of the surface and the interior (e.g. chafe marks, cuts or fissures).
- Embrittlement of the surface (fissuration of the hose material).
- Deformations, which are not in accordance with the natural shape of the hoses, in pressureless
condition or under pressure or in case of bendings, e.g. separation of material layers, blister
formation, squeezing or break spots.
- Leakage points.
- Instructions for installation were not observed.
- Emerging of the hose from the end fittings.
- Damages or deformations of the end fittings which deteriorate the function and stability of the
end fittings or the connection between hose and end fitting.
- Corrosion of the end fittings or the metal inlets, which deteriorates the function and stability.
- Storage and operation periods were exceeded.

6.1 General
General facts about the rescue rams LZR../... und LTR ./..
These rescue rams have been designed especially for rescue purposes. Their main purpose is
to open the gap created by the spreader or the multi purpose tool, because they travel farther than
the multi purpose tool.
Locked-in people can be freed by e.g. pushing away the seats or the car front, by pushing up the
steering pillar or an indented car roof.
The device is suitable for submerged operation in water up to a depth of 40m.
Before the rescue operation begins, the object to be worked upon must be stabilized.
In each country, the country-specific safety regulations must be regarded.
When working in an environment which involves a risk of explosions, do not use motor/engine
powered pumps. Instead, use hand pumps.
When operating rescue devices, wear
- protective clothing
- helmet with visor or goggles
- protective gloves.
During operation of this rescue device, parts of the object worked on with this device may break
away and endanger people standing nearby. Onlookers must be kept at a safety clearance of at
least 5m.
The device may be used in environments submerged in water to a depth of up to 40 m.
6.2 Function and performance
6.2.1 Description
The rescue rams are designed for double-acting hydraulic rams. Retraction of pistons of the
rescue rams is also effected hidraulically.
