Type selection is in accordance with the construction and with diameter and quantity of the lines to be installed. A clearance of at least 10 % for cables and 20 % for hoses should be available.

The R(adius) is also dependent on the lines to be installed. Comply with the statements of the manufacturer. Normally the chain bend radius should be 10 times the largest cable diameter.

The Length of the chain depends on the travel distance and can be calculated with the following formula: L = travel distance / 2+ 4 x radius (rounded up to link pitch)

The Width of the chain (stay length+2d) depends on the number and cross section of the cables to be installed. With slow applications cables can be installed on top of one another, creating extra space (see separator options).

The Arrangements is only to be stated in special cases (see page 29).

The Separator arrangement depend on the application.

The order for an energy chain PLE should contain the following data:

Type / Radius x Length / Width - Connector "Arrangement"; Separator arrangement

Example: travel distance 3 m, bend radius 200 mm, cables: 1x15 mm, 8 x 8 mm, 3 x 12 mm, 2 x 22 mm; the chain is hanging 1 PT55 5 PZ

PLP 220 / 200 x 2325 / 200 - D/E “h“; 5 PZ, 1 PT55

Note: Indicate configuration (p.29), load and strokes per minute at order ! Take minimum bend radii of the cable and tube manufacturers into account. Stretching and shrinking of up to 4% is possible at hydraulics tubes.

All PLE are supplied with the integrated connector, ie. each link can be also be used as connector.

Material:The utilised material is a very high grade glass fibre reinforced polyamide. Resistance to chemicals is very good (excepting acids and concentrated alkalines). The operating temperature range is between -20°C and 100°C.

PLE Stay and separator options

Compared to standard chains the series is characterised by the fact that the sturdy aluminium profile can be steplessly adapted to the requirement. Stay length of up to 800 mm can be realised. The closure system permits quick access to the cables. The separator options satisfy every requirement and guarantees optimal cable protection, even with very high accelerations and travel speed.

PLE (PLE with inserts) is the 100 % solution at high travel speeds. Ideal guidance is guaranteed, ruling out errors when installing cables are prevented. Weight distribution over the chain cross section should be as symmetric as possible.

In the case of restricted installation space preference

should be given to the PLS (PLE with foam stay) . Here too, optimal guidance and protection of cables is guaranteed at high speeds and accelerations. Well known car manufacturers are using this version for many years with great success.(Not available for PL 620)

If this is not possible for reasons of space,The PLP (PLE with plastic intermediate separators (PZ) and horizontal dividers) can be selected. This low cost version permits the reliable guidance of large numbers of cables. The highly variable divider options due axes, the small step of 3 mm in the height setting range and the telescopic layer dividers (PT) permit maximum possibilities for all requirements, even in case of retrospective changes.

The PLE and PLS variants should take preference for extreme applications, as these offer maximum guidance for the cables. Note that it is imperative to avoid multi-layer arrangement of cables with high speeds and accelerations.
