HG Features

• Elephant’s high-tech load chains are approved by DIN 5684, one of the world’s strictest standards.
  This is the special heat-treated load chain of Grade V (100kgf/mm²) whose tensile strength far surpasses JIS Grade V.
• 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 of easier handling shape.
  The opening of the hooks has been made wider for easier handling and working. And, if by any chance the hook is overloaded, there is no fear of its breaking, and it will simply start straightening out gradually, avoiding any load drop or human injury.
• Tough framing.
  The tough gear case, reinforced with four ribs and four knock pins, provides accurate gear centring 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.
• Dry friction discs with longer life.
• Unique chain guide.
• Load sheave with roller bearing.
• Anchor plate avoiding over-lowering.
