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. |
