Technical Specifications

  • High-tech load chains are approved by DIN 5684. Heat treated load chain from ISO Grade T (900N/mm2) which tensile strength far surpasses ISO T class.
  • Double pawls supporting fail-safe brake mechanism. Even if by any chance one of the two pawls becomes unserviceable the other will still remain operative, and the brake system remains secure.
  • Hooks design with ease of handling.
    The opening of the hooks has been made wider for easier handling. However if by any chance the hook is overloaded there is no fear of breaking, it will gradually start straightening out, avoiding any load drop or personal injury.
  • Tough Framing.
    The tough gear case, reinforced with four ribs and four knock pins, provides accurate gear centering and high mechanical efficiency.
  • Rolled-edge hand wheel cover.
    This provides smooth operation of the hand chain when pulled sideways. Strong and least corrosive electrostatic powder painting.
  • Wet friction discs with longer life.
  • Load sheave with sealed roller bearing.
  • Anchor plate avoiding over lowering.
