Usually these masts require a flat or socket wrench, with the quick release clamps you can raise and lower the masts without any tools.
Even with limited space these quick clamps can be easily used, because the lever can be adjusted at any position. Just pull out and release the lever, the strong spring latches the lever at the desired position.
The mast can be extended to any length and securely locks into place by means of a massive clamp. The maximum allowed extended length is marked by a color ring approx. 20cm before the end of each tube. There is no fixed stop which makes it advisable to approach the marking slowly when extending the telescopes.
These masts are ideally suited for portable applications due to the low weight and the telescopic mechanism. When setting up the mast please pay special attention to the clamping length; the clamping length of the mast must be at least 1/6th of the extended length, or at least 1 meter at the minimum. When extending the mast more than 6 meters measured from the uppermost clamping point additional guys are mandatory.
The tubes are made of weather-proof aluminum alloy. The tubes are tapered by 5 mm and the tube thickness is 2mm. Please refer to the following table for weight and dimensions. The stated additional forces refer to a horizontally applied force at the tip of the extended mast - without guys and a mast clamping length of 1/6th. The calculation includes the inherent load at a wind speed of 50km/h (which is equivalent to a wind force of 7).
also we can produce according to clients special requests, and can give proposals.
