Electric Chain Hoist
CHAINster
We are truly proud of the new CHAINster. It tackles loads with enthusiasm, is always available when you need it and will work for a lifetime. It can cope with extreme loads and can be used for almost everything.
Its newly developed chain sprocket does not just give it a longer life, but is also particularly low on maintenance. The slipping clutch ensures that nothing goes wrong, even in an emergency, and its brake is designed for its service life. It is simultaneously both fast and sensitive because of its 6:1 ratio.

Aluminium casing
Benefits:
- Robust aluminium casing
- Space-optimised and flexible dimensions
- Optimum protection against external influences
-
Components easily accessible
The innovative modular casing is based on a central cast aluminium component into which the gearbox and motor have been built in a space-optimised way. The small size achieved as a result of this design ensures flexible use. Furthermore, it offers a robust mounting for the low-maintenance cable guides and even the casing cover is manufactured from solid aluminium. Not a plastic casing.
Robust chain sprocket and chain guide
Benefits:
- Low wear on the chain drive and long operating hours
- Simple and rapid maintenance
-
Reduced operating and maintenance costs
The patented chain sprocket with its additional teeth ensures low wear and low-noise operation. The metal chain guide is extremely solid and can be replaced as a single, easily exchanged unit, just like the chain sprocket.
Prove control system
Benefits:
- Long service life, short downtimes
- Safe operation because of the low control voltage
- Plug-in connectors
-
Fast servicing and minimised operating and maintenance costs
The high-quality, long-lived contactor control system ensures reliability in operation. This system does not regulate the entire current consumed by the hoist motor micro-electronically, but rather a low control current, which then reliably controls a robust, solenoid actuated switch (the contactor).
Here, too, the connectors are naturally all plug-in connectors and maintenance can thus be carried out quickly at low cost.
Ergonomic load hook
Benefits:
- Ergonomic load handling
- Large, non-slip grip area
-
Safety catch built into the hook
Materials handling is easy and convenient, even over long periods of work, thanks to the ergonomic load hook.
The large, non-slip grip zone guarantees safe connection of loads and thus reduces the risk of injury. Reliable slinging of the load is also guaranteed by the integrated safety catch.
Easy control
Benefits:
- Rapid and precise load handling (up to 6:1)
- Cable-bound control switch (standard feature)
- Radio remote control (optional)
-
Flexible equipment levels
The two hoist speeds, up to 6:1 depending on the load, can be controlled as conveniently as the optionally available motorised carriage. The standard, cabled control switch can be replaced by a radio remote control for greater freedom of movement. This offers the crane controller the ability to be more flexible in his choice of location. The HandyMaster can also be used for all handling tasks.
Integrated lifting limit switch
Benefits:
- Safe shut-down without wear to the slipping clutch
- Well protected against environmental influences
-
No loss of build height
The motor is shut down smoothly at the top and bottom position thanks to the lifting limit switch which is fitted as standard. The slipping clutch is protected against wear by this secure shut-down. Well protected against environmental influences and with no loose parts on the hook block, the lifting limit switch is built into the interior of the robust aluminium casing and thus does not cause any loss of build height.
Overload protection
Benefits:
- Protects hoist, crane and building structure against overloading
- Precise adaptation to the circumstances
-
Enhanced safety at work
The CHAINster has a slipping clutch installed between the motor and the hoist brake as standard. Overload damage to the hoist, crane or building structure is prevented by this system. The slipping clutch is easy to service and drastically enhances safety at work. A broad control range and fine precision adjustment allow flexible and exact adaptation to local circumstances. The load is held safely and reliably without any slipping, even with the motor switched off.
Innovative cable guide
Benefits:
- Plug-in connectors
- Tool-free assembly and disassembly
- Fast servicing
-
Minimised operating and maintenance costs
All connections are plug-in and, together with the innovative cable guide, this creates an optimal installation and maintenance environment. The CHAINster can thus be configured quickly and individually and the operating and maintenance costs are reduced.
Versatile in use
Benefits:
- Flexible mounting
- Upper hook, suspension eye, push or motorised carriage possible
- Optimal space utilisation
-
Compact dimensions and space-saving carriages
The CHAINster can be customised to your needs, whether you want an upper hook, push or motor carriage. It is also able to make load handling significantly easier at practically any location with its versatility thanks to small dimensions and the wide ambient temperature range from -20 °C to +50 °C. Thanks to its pre-equipment the hoisting equipment, motor carriage and crane can be controlled centrally from a hand-held control.
Frequency inverter (CHAINsterGT)
Benefits:
- High hoist speeds under partial load
- Lower hoist speeds for pinpoint placement of loads
- Damping of shock loads and the effect of sudden impacts
- No extra work for commissioning (Plug & Play)
The integrated CHAINsterGT frequency inverter allows a broad speed range and therefore effective, fast yet precise load handling. In addition to slack chain shut-down, the slipping clutch and the brake are permanently monitored and shock loads on the hoist are prevented.

Types
Die Hubwerkseinstufung (FEM/ISO) ist eine Kennzahl die sich primär aus der mittleren täglichen Laufzeit des Krans und der tatsächlichen Last zusammensetzt. Hierbei wird auch berücksichtigt wie oft das Hebezeuge hierbei Höchstbeanspruchungen oder nur geringen Beanspruchungen ausgesetzt ist oder wie viele Starts/Stops erfolgen.
Vereinfacht:
1Am / M4 = Die mittlere tägliche Laufzeit beträgt rund 1 Stunde und das Hebezeug wird häufig höchstbeansprucht und laufend mittleren Beanspruchungen ausgesetzt.
2m / M5 = Die mittlere tägliche Laufzeit beträgt rund 2 Stunden und das Hebezeug wird häufig höchstbeansprucht und laufend mittleren Beanspruchungen ausgesetzt.
