High-speed telescopic covers

An essential consideration in the design of a telescopic cover is the traverse speed. Up to 15 m/min the covers do not need specific buffers, except in special cases. Between 15 and 30 m/min specific accessories are required to cushion the impact between the elements in order to make them last longer. From 30 to 60 m/min scissors are fixed on the cover. Thanks to their “concertina” movement, they prevent impact between the elements and allow them to move smoothly.

 

FROM 15 TO 30 mt/min.

A ) SPECIAL ROLLERS FOR RECIRCULATING BALL GUIDES

Turned plastic rollers with central groove specifically designed to glide over screw-covers. Fixed on a specific support block, therefore easily replaceable.

B ) CLOSING BUFFERS

Buffers in anti-vibration rubber 70% NBR SHORR hardness 80 positioned on the rear part of the leading edge. In various shapes and dimensions according to need.

C ) OPENING BUFFERS

These stock absorbers are made up of a part in brass and a part in 100% NBR rubber with SHORR hardness 80. They are positioned in the front part of the element, immediately behind the oil wipers. Allow 15 mm space for each one.

FROM 30 TO 60 mt/min.
