Mast - fixing in 1 level

The calculator works with a simple mast anchored in one level and on the top of the mast there is an antenna placed. When counting, the calculator supposes that the height from the ground to the place where the rope is tied to the mast is much bigger than the distance between the place where the rope is tied to the mast and the antenna on the top. The mast is considered to be a solid tube determined by external and internal diameter. After entering all the necessary data (heights and distances, parameters of the antenna, material of the mast, speed of the wind), the system will count the forces exerting on the ropes and the mast. Moreover, it will provide you with the assessment of the safety of the construction as a whole in term of the selected mast.

The results can also be used as an orientation map for construction of a mast with anchoring in more levels.

  • Camouflage ropes 2. 8. 2018

    We started production of "Camouflage look" of two sizes of Mastrant-P – called Mastrant-C. It is targeted for customers who need "invisible" guying in specific environment. The main color is tan with brown “dots”. They are available in sizes "3+" (3.5 mm, 9/64") and "6" (6.2 mm, 1/4"). 

     
  • New size of "P" rope: 3.5mm (9/64") 30. 7. 2018

    We started production of new size of rope Mastrant-P which fills the gap between "size 3" (diameter 2.6 mm) and "size 4" (diameter 4.4 mm). It is "size 3+" and has diameter 3.5 mm (9/64"). Breaking strength is 300 daN (about 300 kg or 660 lb.).  
  • Strength of P4 and P5 26. 4. 2018

    We are updating the ratings for Breaking Strength and Safe Working Load for our most popular rope, 4mm and 5mm Mastrant-P. We began improving the construction of this rope in our production process more than 6 years ago and have been testing samples from each run. We are now satisfied that the changes have resulted in consistent, permanent improvements. Here are the new ratings:
    Mastrant-P, 4 mm: BS=440 daN (about 440 kg, 970 lb.), SWL=132 daN (about 132 kg, 290 lb.)
    Mastrant-P, 5 mm: BS=540 daN (about 540 kg, 1190 lb.), SWL=162 daN (about 162 kg, 360 lb.)
