GC Hoist

Listing ID #4183731

The Next Generation GC Chain Hoist With A Global Concept From INDEF

• Reduction gear
  Designed to withstand fatigue and wear for the whole lifetime as required by the selected service groups FEM/ISO (2m/M5 or 3m/M6). It is totally enclosed in a cast light alloy housing. The cylindrical gears with helicoidal teeth are thermally treated and made of highly resistant steel. The gears are mounted on spherical bearings and are lubricated for life in an oil bath.
  
• Suspension eye
  Made from hot-pressed carbon steel and is affixed to the hoist body by two steel pins which are easy to inspect to prevent accidental removal. The suspension eye with its fixing holes and eyebolt, allows both the rigid suspension of the hoist by means of the two holes, or by means of the oscillating eyebolt. Hook suspension version is available on request.
  
• Self-braking motor
  Incorporates asynchronous three-phase cylindrical rotor. The electromagnetic DC brake with asbestos free lining is designed for a high number of starts and does not require any adjustment. The light alloy brake casing, has radiating fins that guarantee high thermal dissipation. The motor is fan cooled externally and is produced with double polarity for two speed hoists.
  
• Lifting chain
  Calibrated alloy steel chain of high strength and of special quality, sourced from the world's best chain manufacturers. The heat and galvanizing treatments applied to the chain ensure high resistance to the wear, aging and corrosion.
  
• Load sprocket
  Machined, heat hardened five pocket load sprocket is made of high strength steel to ensure optimum sliding and a long life of both: the chain and the sprocket.
  
• Chain guide
  Facilitates smooth insertion and extraction of the chain into the sprocket.
  
• Upper limit buffer
  Consists of a cylindrical shape polyurethane shock absorber, with a central hole for chain crossing. It is placed against the upper surface of the hook block to deaden and reduce the dynamic effects caused by the collision of the hook block against the hoist body in the upper hook position. It causes the clutch device to slip avoiding the impact between metallic parts.
  
• Descent limit stop
  Is made in high resistance plastic material reinforced with fiberglass. It is placed on the descending length of chain into the chain box and limits hook run during lowering.
  
• Chain box
  Is made of shock-resistant plastic. It is fixed to the hoist body by a bolt that permits high level of freedom of movement. It can be provided in several sizes to suitably contain the length of chain for the required hook path.
  
• Overload Clutch
  The overload clutch is composed of a friction coupling with double pressure disc and an asbestos free friction plate. The sliding surfaces are immersed in an oil bath in order to guarantee the heat dissipation generated during the slipping. The clutch device is pre-loaded by means of spring washers and adjusting nut.
  The slipping clutch, when it has overload device function, is automatically activated at any point of the hook travel, whenever the resistance force caused by the load is more than the resistance force of the device (ex.: in overload situation) in situation of physical overload or activation of upper and lower hook travel limits.
