Stahl AS7 Wire Rope Hoist
- Stahl has two designs for load capacities up to 125,000 kg
- Innovative drive technology with cylindrical rotor motor with monodisc spring-loaded brake
- Stationary model or double rail crab for systems and crane manufacture
- Compact construction and low approach dimensions
- Higher load capacity, hoisting speed and lifting height as twin hoist
- Largely maintenance-free, low wear, long service life in acc. with FEM
- Optionally available in explosion- protected design complying with ATEX and IECEx
Rope and Rope Guide
- Highly flexible special rope with long service life
- Field-proven enclosed rope guide in spheroidal graphite cast iron has no temperature limitations
- The GJS material (previously designated GGG40) is suitable for highest and lowest temperature ranges
- 360° rope tensioner, avoiding the formation of slack rope
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
Overload Cut-Off
- Continuous electronic monitoring of suspended loads
- For systems manufacturers: overload cut-off is also possible for 1/1
- or 2/2 reeving, measuring the load on the gear
- Maximum load limited by gear sensor. With multiple reeving, load measurement at rope anchorage is possible as an option.
Hoist Gear
- All gear steps with lifetime lubrication in oil bath
- Minimum noise development thanks to state-of-the-art technology
Control and SLE Motor Management
- Condition monitoring as standard
- Inching operation is suppressed thus reducing stress
- All common control voltages available
- High degree of safety thanks to overdimensioned contactors
Brake
Low-maintenance asbestos-free brake; needs no adjustment- Long service life thanks to overdimensioned braking torque
- Brake easily accessible for inspection from outside
- Motor management ensures low wear
- IP 65 protection
Meter
- Special-purpose motor for hoisting applications
- Classified according to FEM (ISO), high duty cycle and switching operation frequency
- IP 55 protection, insulation class F
- Motor outside rope drum, highly efficient motor cooling, maintenance-friendly
- Temperature control by ptc thermistor
Rope Drive
- Optimised ratio of drum to sheave diameter ensures low wear on rope
- Flexible and long-lived wire rope
- Wear-resistant return sheaves, fine machining provides rope-friendly grooves in rope drum
- Drum easily accessible for rope replacement
- Robust bottom hook block with low head room in spite of large dimensioning of hook
