Stahl SW Winch
- Stahl has two frame sizes, SW10 and SW16
- Load capacity of 25,000 kg to 160,000 kg
- Four FEM classifications available
- Largely maintenance-free, low wear, long service life
- Compact construction and short approach dimensions
- Powerful hoist motors for great heights of lift
- Equipped as standard with a condition monitoring unit
- Slightly angled return sheaves
- Optionally available in ESR design (extended speed range) with up to 1.7 times hoisting speed at partial load
Paint
- Standard paint treatment as per RAL 6018 yellow-green and RAL 7021 greyish black
- High-quality primer and top coats for standard applications
- Off-standard paint treatment for outdoor use or corrosive ambient conditions
- Shade as per customer‘s requirement
Rope and Rope Guide
- Robust guide elements in spheroidal graphite cast iron
- Load sensors to monitor overload
- Two independent ropes
- Rope overwind protection and slack rope monitor
- Pressure roller is possible as an alternative to rope guides
Rope Drive
- Wear-resistant return sheaves, fine machining provides rope-friendly grooves in rope drum
- Rope sheaves in bottom hook block set at an angle to return sheave, no fleet angle
- As an option, motor-driven rotating load hook with inverter
- Robust bottom hook block with low headroom
- Optimised ratio of drum to sheave diameter ensures low wear on rope
- Flexible and long-lived wire rope
- Drum easily accessible for replacing rope
Hoisting Gear
- Reliable and maintenance-free thanks to a statically determined three-point suspension
- 3-step spur gear
- Gear limit switch
- Supplementary limit switch for top hook position activated by bottom hook block as standard
Crab
- Convex running surface of wheels
- For high load capacities, 6 wheels reduce the wheel load
- Flanged wheels on hoist gear side, guide rollers are also available as an option
- Wheels without flanges on the opposite side
- Even distribution of wheel load
Motor
