CompactTrac, PowerTrac, TopTrac, HyTrac
The continuing technical progress in the elevator industry, which includes larger and faster installations in conjuntion with smaller sheaves, has markedly raised the demands on hoist ropes. Gustav Wolf has already acted on this trend by developing new ropes in diameters of less than 8 mm. Gustav Wolf has taken an additional step by introducing a new generation of elevator ropes which are designed to meet the increasing demands of existing and new installations for diameters larger than equal to 8 mm.
The result is our newly-designed CompactTrac and PowerTrac product -both with compacted strands. CompactTrac and PowerTrac feature:
Increased service life; through greater bending resistance
Higher wear resistance; the larger surface area of the outer strands leads to a better seat in the groove of the traction sheave resulting in a reduction of the concentrated (point) load on the elevator ropes. The surface pressure is more evenly distributed over the ropes resulting in minimization of wear and noise.
Reduction elongation; through the higher metallic cross-section the elongation properties of the ropes are considerably improved which reduces labor required for rope shortenings.
Smaller diameters; with their higher breaking loads it may be possible to achieve cost savings on new installations through the use of smaller diameter ropes.
Thanks to a longer service life as well as ease of maintenance, Gustav Wolf succeeded in developing a new generation of elevator ropes. They will be the perfect match for the future technical and commercial demands of elevator technology.
Our top of the line product TopTrac incorporates a high metallic cross-section and superior bending resistance. TopTrac features:
9 outer strands to reduce the bending pressure on individual wires = highest service life.
Increase in the fill factor due to the double parallel lay = transfer of higher tensile forces.
Parallel stranding construction reduces rope pressure = maximum wear resistance.
HyTrac
The new Hybrid rope
8 x 19 W-SFC
In comparison to steel core ropes the same breaking load but 20% less weight
SFC = 15 times stronger than steel
