Select the right tow wire for the elevator
To choose the right tow wire for the elevator, it is necessary to pay attention to the following items.

Conventional elevators are short in height and less than 1.6 m / s
In gearbox elevators, the motor is usually installed 1-1 and the motor has a large traction pulley and a V-shaped groove (figure above). Suitable tow wire for such elevators will be hemp kernel with 8 * 19 flood texture and hemp kernel F819 SFC.

If the grooves are U-shaped, or the main pulley is small, or more loose pulleys are used depending on the situation, it is better to use an eight-strand hemp core tow wire with Warrington texture with technical code F819 WFC.

Elevators with an average height of 30 to 60 meters and a speed of 4 m / s in these elevators must use 8-core steel core wires that – for example in the Gustav Wolf brand coding system – produce a special type of steel cord tow wire In the center of the brain, a thin layer of hemp is used for more softness and better lubrication. These towers are known by the technical code PAWO F3 and PAWO F7. These models of towers are of the steel core type, which are sometimes referred to as semi-steel or semi-hemp tow ropes in the market term, which is not technically correct.

If the elevator with medium height conditions is installed 1-1 (one by one) and the main pulley groove of the motor is V, PAWO F3 tow wire with seal texture can be used. If the type of installation is 1-2 (two by one) or other types (figure above) or the motor groove is U or the number of round weeds is more than one, it should be made of PAWO F7 tow wire which has texture Warrington is to be used.
High-altitude elevators with a movement length of more than 60 meters and a top speed of 4 m / s. Has been designed.
