The brake release device permits the hoist brake to be released manually and thus the load to be lowered during a power cut. As an option, every hoist can be equipped with this supplementary equipment to the standard brake.
Redundant brake system provides increased safety. Intercept and holding brake, prevents the load falling even if the gear should break. Control is effected with a centrifugal switch or safety PLC.
Smooth starting and braking characteristics. Load swing greatly reduced. Fast, precise positioning of the load, corrective switching operations rarely necessary. The reduced dynamic load means a longer service life for hoist motor and gear and reduces stress on the whole system.. ESR function (Extended Speed Range) for higher hoisting speeds with partial load. Worldwide approvals for all frequency inverters.
Simple to install, parametrise and operate. Standard speed range 1:10, up to 1:30 as an option. SPS compatible to super-ordinate systems (optional). All internationally customary mains voltages are available. Also available in design for installing in panel box.
Prevents sagging of the load even when the gearbox fails. Permanent brake, drive and load monitoring. Two synchronously controlled hoist motors and brakes. Two manually releasable brakes for emergency lowering. Robust, completely encapsulated system. Service and safety brake of identical design. Up to 60 % higher load capacities when transporting non-molten metals.
Visual and acoustic signal transmitters such as horn and flashing light can be mounted on travel carriages. The signal transmitters can be activated by a button on the control pendant.
SLD four-digit 7-segment load display (Stahl Load Display), large format, luminous red, available with various interfaces including CAN. Choice of 60, 100 or 150 mm digit height. No additional sensor is required as the standard load sensor is used.
Continuous load monitoring by overload cut-off even if hoist is at a standstill. Overload protection with ALC automatic load control. Load spectrum memory for load-related operating time summation. Monitoring of the motor temperature of the hoist motor and travel motor. Operating data registration, e.g. operating hours, load spectrum, motor switching operations and load cycles. Data exchange with PC possible.
In standard version, the hoist is equipped with a gear limit switch for top and bottom hook position and an operational limit switch for top hook position. As an option, up to eight switching elements can be fitted to the switch. This permits for example further stopping positions and operational limiting in bottom hook position.
The AS 7 series is designed in two variants for the upper lifting capacity range to 125,000 kg. The ASR 7 wire rope hoist is the reduced version of the tried-and-tested AS 7 wire rope hoist. It is designed for a safe working load range from 20,000 kg to 32,000 kg and closes the gap between efficient use of the SH wire rope hoist programme and the AS 7 wire rope hoist programme. The revised design as twin hoist covers the same fields of application as the AS 7 wire rope hoist, albeit with higher lifting capacities, greater lifting heights and faster lifting movements. One important safety feature of the AS 7 wire rope hoist when designed as twin hoist is its exact positioning of the load. As the rope of the twin hoist runs in opposite directions simultaneously, the load is lifted and lowered without any sideways movement of the hook.
If wanted, the complete wire rope hoist programme is also available in explosion-proof design for Zone 1, Zone 2, Zone 21 or Zone 22.
