  • Hook coated with bronze
  • Gear limit switch
  • Special paint finish to 240µm
  • Power supply with flat cable
  • Protection rating IP66
  • Ambient temperature -20 bis +50°C
  • Stainless steel load chain, hook and hook block

  • Flexible usage

    Benefits:

    • Upper Hook, push trolley or motor trolley possible
    • Optimum utilisation of space
    • Compact installation dimensions and travelling machineries

    The SKex can be individually configured with an upper hook, push trolley or motor trolley. Optimal construction and approach dimensions make for maximum movability and flexible load handling.



  • Convenient operation

    Benefits:

    • Safe and steady operation of both the load and the crane
    • Robust EX design

    Both lifting speeds (4:1) are as easily controlled as the optional motor. The especially robust control pendants were designed for use in explosive atmospheres.



  • Proven contactor control

    Benefits:

    • Reliable and robust contactor control
    • Safe operation due to low-voltage control system
    • Extended lifetime

    The high-quality, long-life contactor control system makes for reliable operation. The lifting motors' high power “only” flows through the control system, a robust switch operated using a low control voltage.



  • Robust casing and components

    Benefits:

    • Powerful and durable industrial design
    • Good protection against external influences
    • Low maintenance costs

    The SKex combines compact installation dimensions and a robust casing. Also for its interior the electric chain hoist, based on standardised compontens, relies on highest quality and durability.



  • Powerful

    Benefits:

    • Hoist motor, completely closed, cooled with fan
    • Lifting and travelling motor overheating protection
    • Slipping clutch as overload protection

    The high-performance motors are subject to pressure-resistant capsuling (‘d’), completely sealed and fan-cooled. Temperature sensors (PTC themistor) in the motors’ winding and break housing oversee the temperature and offer additional protection against overheating. Mechanical overloads are prevented by the standard slipping clutch.



  • Reliable lifting

    Benefits:

    • Durable, stainless steel load chain
    • Ergonomic and self-locking load hook

    The galvanised load chain and hook, fitted as standard, are also available in corrosion-resistant stainless steel. Bronze-coated load hooks can also offer additional protection from sparks.

Electric Chain Hoist
Applications

Potentially explosive areas for gases and dusts


Explosion hazard areas are separated into zones. This classification, which defines the scope of protective measures to be employed, depends on the type, duration and frequency of explosive atmospheres.


The electric chain hoist SKex is approved for the following areas und zones:
