Gear limit switches for cranes and hoisting gears safe precise reliable Gear and spindle limit switches from the market leader: precision manufactured, preconfigured, for fast installation GKN Stromag has been building gear and spindle limit switches for over fifty years. With a wide range of gear systems, switching contacts, and housings of metal or plastic, we can offer solutions for every application. All analogue and digital encoder systems can be integrated. Our gear limit switches reliably switch off sequences of movements, and position or restrict these with independently and precisely adjustable cam discs. Whether simple chain hoists, compact hoisting gear, open winches, or complex STS, mobile, or any other type of mobile cranes, GKN Stromag provides customer solutions configured optimally to any application. The modern designs present a wide range of standardised solutions for reliable cutoffs. Securing loads, protecting buildings and machinery: Limit switches for cranes and hoisting gears As a measure to protect equipment and machinery, hoisting gears must be limited at their top and bottom cutoff points. The gear limit switches from GKN Stromag provide for this reliable cutoff and ideally are attached directly to the drum. When integrated with optional, intelligent encoder technologies, these gear limit switches can easily determine absolute positions to a high precision. These values can then be converted into reliable additional data like e.g. sense of rotation and overspeed. Data can be transferred to the manufacturer’s controller via a customer bus interface. The plant operator benefits from optimised cost control when these status parameters and appropriate preventive measures are integrated in the condition monitoring system. The ideal solution for compact hoisting gears! Planetary gears Series 51 » Patented planetary gears » Cam adjustments at fixed position in housing (simple and precise adjustment) » Patented block adjustments » Large cam disc diameter » Modular design with many identical parts » 4.1–16,000 usable revolutions » 1 to 8 contacts » Various housing designs » Approved under BGV-C1 (stage engineering) » Direct drive of multiturn encoders Function and application Series 51 gear-cam limit switches are universal, mechanical switchgear that can map a wide range of shaft rotations to the angular displacements of the installed cam discs. These cam discs actuate the mechanical switching contacts. They are used everywhere angles or distances cannot be limited directly with switchgear, but only indirectly on the basis of the measured shaft angle. One classical example of this application involves limiting the hook lift of a crane hoist. Worm gears Series Light Cam® » Low cost plastic housing IP 65 » Gears of plastic » 0.85 to 880 usable revolutions » 4 or 8 contacts » Suitable for the integration of encoders and potentiometers » Encoder attachments possible Function and application Light Cam® Series gear-cam limit switches are universal, mechanical switchgear that can map a wide range of input shaft rotations over the full angular displacement of the cam discs. These cam discs actuate the switching contacts. The classical applications of these limit switches are e.g. crane hoist, traversing, and slewing drives; wind turbine generator systems; bucket conveyors; etc. In particular where EN 60947 T5-1 and IEC 947-5-1 prescribe forced opening switches eliminating potential harm to persons, there is no alternative that is more economical than gear cam limit switches. ion! s ATEX ver n a s a le ab Also avail Spur gears Series 100 » Highly robust metal housing » Steel sheet IP 65, grey iron IP 66 » Gears of plastic or metal » 0.153–15,300 usable revolutions » 2 to 14 contacts » Potentiometer facility » Explosion protection ATEX 95 » (gas zone 1 and 2, dust zone 21 and 22) Function and application Series 100/110 spur gear limit switches are robust limit switches in a metal or plastic housing for use under difficult, mechanical conditions. Owing to the pretensioned gears, potentiometers and single turn encoders can be actuated free of backlash. Spur gears Series 110 » Robust plastic housing » Gears of plastic or metal » 0.153–420 usable revolutions » 2 to 12 contacts » Potentiometer facility Function and application Series 110 gear-cam limit switches with dry running moulded gears (acetyl copolymer). Microswitches as snap switches or touch contacts, break and make contacts with positive, also form-closed opening operation. Switching point intervals adjustable continuously or in 4° steps within the utilisable rotation range. Any installed position. The solution for heavy duty applications! Spur gears Series 410 » Heavy aluminium housing IP 65 » Gears of metal » 0.08–263 usable revolutions » 5, 9, or 14 contacts » Potentiometer facility Function and application Series 410 gear limit switches are used for the independent restriction of movements by all types of electrically operated hoisting gear. This model presents an extremely robust design making it ideal for applications under difficult operating conditions, e.g. in seaports and steelworks. Owing to the generously sized housing, the limit switch can be fitted on its sides with large diameter entries for thick cables. Spindle gears Series 62 » Heavy aluminium / grey iron housing IP 65 » Usable revolutions » Up to 42 » Up to 62/125 size 3 and 4 » Fixed and adjustable series contacts possible size 2 Function and application Series 62 spindle-cam limit switches (SNE) are used for the independent restriction of all types of electrically actuated hoisting gear, e.g. travelling, gantry, luffing cranes; sluice gates; and general industrial applications, for the direct cutoff of main currents at the emergency end positions. This series presents an extremely robust housing in seawater-resistant sand cast aluminium, making it ideal for operations under difficult conditions e.g. in steel mills and seaports. Robust and ideal for harsh environments! Worm gears Series HGE » Highly robust aluminium housing IP 65 » Gears of metal » 8 to 345 usable revolutions » 2 or 16 contacts » Potentiometer facility » Encoder attachments possible Function and application Series HGE gear limit switches are universal, mechanical switchgear for general industrial applications. They consist of a reduction gear set and one or two contact chambers taking the switching contacts and the assigned cam discs. The reduction gears reduce a high number of rotations transferred to the gear limit switch’s input shaft to a max angle of 320° at the cam disc (on 40° cam discs). The adjustable cam discs then actuate the mechanical switching contacts. When fitted with mechanical forced opening switches complying with EN 60947-5-1, limit switches are the ideal choice in hoisting gear. Levers Series HHEV » Highly robust aluminium housing IP 65 » Usable 85° lever angle to each side » 2 to 8 contacts Function and application The HHEV Series lever limit switch is used everywhere movements can be cut off directly, e.g. traverses by gantry bridges or trolleys, bucket conveyors, and other hoisting gear. The switch is attached in such a manner that traverses cause the switch’s lever to move on a switch actuator, displacing it from its centre position.
