Our roller payout guides can be configured with or without monitoring functions. Roller payout guides with a monitoring function are fitted with contact-free proximity switches or mechanical limit switches. Proximity switches can be operated at a connection voltage of 15-250 VAC or 15-30 VDC.
The cable deflection guide with vertical positioning is suitable for cable ducts. Typically, the commonly available deflection guide type ULTV is installed vertically in a concrete shaft for connecting the cable. In principle, it should be installed underneath the cable deposit. The necessary fastening bores are provided.
The winding device consists of a cross spindle and a guide finger with a roller chain for the connection to the cable reel. The installation of the winding device to the cable reel ensures that the cable is evenly wound onto a cylindrical, widely winding reel body. This prevents the disorderly arrangement of several cable layers on top of each other and protects the cable from slipping or damage. The chain-driven version can be retrofitted to existing systems.
The deflection link chain was specially designed to allow the safe guidance of cables when tracked vehicles, such as mobile diggers or loading machines, are going round bends or are carrying out swivelling movements. Tracked vehicles usually have a restricted turning circle which poses a constant risk to the windable cable. The risk of damage to the cable is avoided or significantly reduced by fitting our deflection link chain.
The cable pulling grip ensures the strain relief for the cable at the feed point. The surface clamping prevents any point loads on the cable. It preserves the cable sheath and extends the cable's service life. The 800 mm long, galvanised cable pulling grip is adjusted to the cable diameter and, for safety reasons, it is calculated with 3 times the maximum tensile force.
The cable deposit roller, type series KL, is used to minimise any permanent contact between the cable and the ground so that contamination of or damage to the cable can be prevented.
The deflection horn, which is split lengthways, including the chain and screw fastening prevents any kinking of the cable when passing the cable fixed point. The arrangement is horizontal and sufficiently far away from the track centre so that the horn can turn without any obstruction.
Our hose reels are fitted with a rotary valve for air and water at a maximum of 10 bar of medium operating pressure (= default). The nominal width (opening) of the rotary valve is according to the specification for the type series. (The hollow shaft of the cable reel is equal to or bigger than the rotary valve.) In principle, a torque bracket is fitted. The rotary valve is available with an additional cover over the valve for a small surcharge on request. Other media, such as hydraulic oil, gas, vacuum, special fluids, acids, lyes and similar media are available on request.
This switch is used for monitoring the reel positions "full" and "empty" as well as for other monitoring functions. (It is not a safety switch.) The switching cams are designed for a maximum power of 5 A and 250 V. The limit switch is located either in the slip ring housing or outside that housing in its own housing. (It is driven by a stainless steel chain.) Alternatively, other limit switches, proximity switches or transmitters can be installed.
Thermally controlled stationary heaters at various output levels. Insulated installation in the slip ring housing. We recommend that a heater is installed in locations where low temperatures can occur or where the temperature fluctuates across a very wide range (within a short period of time).
Fibre-optic cables are used to transmit optical signals. The so-called fibre-optic cable transmitter realises the transition between the rotating part (reel body) and the fixed part. The transmitter is adjusted to the winding length of the cable and to the number of fibre-optic cables. The connection is made via connectors. The transmitter is either installed inside the connection to the slip ring assembly or it is located in its own housing. Either way, the installation location is inside the heated space.
