MSL Crank masts
These telescopic masts are manufacted from anodized aluminium square tubes. They are equipped with a rope hoist and function by crank handle. The masts are particularly recommended for the stationary employment (for example of antennas, measuring instruments, headlights and much more besides). It is possible to attach an elctric drive which allows a remote control of the mast. Due the modular construction masts from 2 up to 5 segments can be supplied. These masts reach a height from 2 up 20 meters.
The indiviual segments of the telescopic masts are led from plastic sliding guides with high firmness. All the segments are connected with stainless steel cables and brass rolls. All connections are bolted with rustproof screws. The driving mechanism works by a rope winch or threaded spindle containing an integrated bracket. Combined with its own weight an unwanted sliding in of the mast is hereby prevented. The individual stroke elements drive out and in at the same time. A secure stop is possible in any intermediate height. The maximum at any heigt is limited either by mechanical stops or concerning the electric drive by automatic switches. |
