The AS 7 wire rope hoist programme is the innovative classic in hoisting and crane technology worldwide. The modular system enables innumerable combinations of the subassemblies for customised solutions.
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.
In spite of its high lifting capacity, the AS 7 wire rope hoist with its double rail crab is surprisingly compact. The AS 7 is particularly suitable for high safe working loads to 80,000 kg or crane systems requiring a high ISO classification according to FEM/ISO standards
As twin hoist, the AS 7 ZW wire rope hoist enables a lifting capacity to 125,000 kg, higher lifting speeds and exact positioning without sideways movement of the hook.
The AS 7 wire rope hoist can also be operated as custom solution with a monorail trolley underneath the crane bridge.
The AS 7 wire rope hoist can be coupled to another type of wire rope hoist like, for example, an SH wire rope hoist for synchronous operation in tandem mode per radio remote control.
The different models and trolley variants allow not only a wide variety of uses, but also very individualised solutions tailored to specific requirements.
Stationary model
The AS 7 wire rope hoist can be used as stationary hoisting or towing equipment, for example in systems manufacture. Depending on the application, the rope lead-off angle, the attachment of the hoist and the mounting position of the hoist motor can be varied.
OE double rail crab
The OE double rail crab is intended for use on double girder overhead travelling cranes. The extremely compact construction makes very low approach and headroom dimensions possible and the available space can thus be used to the full. The double rail crab is available with various track gauges for the whole load capacity range.
Twin hoist
The AS 7 ZW wire rope hoist can also be used as stationary hoisting equipment or with the OE double rail crab.
Horizontal towing equipment in systems building
The AS 7 wire rope hoist used as horizontal towing equipment in systems manufacture
Vertical towing equipment in systems building
The frequency controlled AS 7 wire rope hoist used bolted to the floor as vertical towing equipment in systems manufacture.
Guided load lifting
The AS 7 wire rope hoist with guided load pick-up.
Double rail crab
The AS 7 ZW wire rope hoist is mainly used with a double rail crab on double girder overhead travelling cranes.
Angle of installation
The AS 7 wire rope hoist can be mounted in various angle ranges. For rope drives with bottom hook block the wire rope hoist must always be installed with its longitudinal axis horizontal.
Single-grooved rope drum (Standard reeving)
The model with single-grooved rope drum is used for stationary hoisting or towing equipment or combined with various travel carriage variants.
Double-grooved rope drum (True vertical lift)
If true vertical lift is required, we recommend this model with double-grooved rope drum (right-/left-hand thread). This version can be used both in stationary form or with travel carriages.
Double-grooved rope drum (Reeving for multiple load pick-up points)
The model with double-grooved rope drum (right-/left-hand thread) is used for many lifting and towing tasks where the load must be picked up at more than one point and true vertical lift is required.
Twin hoist (Reeving for true vertical lift)
Independent of the grooving of the rope drum, stable guiding of the hook and precise positioning of the load are guaranteed.
Although they are already first-class in their standard design, you can make the hoists even safer, more economical and more convenient with a range of mechanical, electrical and electronic options. They simultaneously improve performance, prolong service life and make it possible to adapt the hoist individually to specific requirements.
Here are some of the options frequently used.
Control pendant
Robust control pendant with EMERGENCY STOP palm button and control cable
All switching elements for hoist, cross, and long travel are 2-step
IP65 protection
Additional buttons, such as horn activation, can be easily fitted

Also available in explosion-proof version
Other radio remote control units optionally available on request
SMC Multicontroller
Continuous load monitoring by overload cut-off even if hoist is idling
Overload protection with ALC automatic load control
Load spectrum memory for load-related operating time summation
Operating data registration, e.g. operating hours, load spectrum, motor switching operations and load cycles
Data exchange with PC possible
Travel limit switch
Travel limit switch on crab available as option
Limiting for both directions of travel
Switchover from “fast/slow” (predisconnect)
Switch contacts designed for control current
IP66 protection
Operational hoist limit switch
Two versions are possible: cut-off in top hook position or cut-off in top and bottom hook position (stationary, push trolley, electric trolley)
Activated by the bottom hook block
Gear-type limit switch
Various functions possible: e. g. routine operational cut-off in highest or lowest hook position or switching from “fast” to “slow” before the stops
IP55 protection, optionally IP66
Spring-steel chain guide
Heavy high-tensile chain guide for rugged use
Enclosed chain guide
Extremely wear-resistant case-hardened chain sprocket
Bypass brake
Second brake for increased safety
Identically dimensioned
Second brake acts in force transmission directly on the load, i. e. bypassed the slipping clutch
As an alternative to the bypass brake, a second hoist motor brake is available
