Basics of wire rope hoists

Wire rope hoists designs vary according to the types of wire rope hoists, and the basics of standard wire rope hoists are the same.

The proprietary series built, rope hoist unit would be selected from our extensive range of units which have a worldwide reputation for reliability, modern design, safety and the very latest Electric Wire Rope hoists manufacturing techniques.

  • The modular design forms a very efficient, compact visually aesthetic unit.
  • The rope hoist transmission train is a direct drive type with no coupling.
  • The wire rope drum is mounted in maintenance free bearings located within the rope hoist bearer frame. The drum is accurately machine grooved to accommodate the rope hoisting wire rope in one layer. And is designed to leave a minimum of 3 (three) turns on the drum when maximum lift height is reached.
  • A wire rope guide is provided to prevent slack wire rope  and to smoothly guide the wire rope  onto the drum.
  • The wire rope is securely attached to the drum with 3 (three) wire rope  clips.
  • The bottom hook block is of the safety type, having fully guarded deep grooved sheaves, running in sealed ball bearings. The hook is a forged steel single point “C” Type, mounted on a ball thrust race and fitted with a spring return safety catch.

The special non-rotating rope hoist wire rope  is manufactured from high strength galvanised steel, the standard construction is 6×36+SES with a minimum factor of safety of 5:1. Over-rope hoist/over-lower limit switches are provided located within the rope hoist control panel. The electromechanical overload devise prevents the accidental lifting of loads over the safe working load whilst still allowing lowering.
The Rope hoist & Travel drive motors with integral brake are totally enclosed, fan cooled, squirrel cage induction type, having class “F” insulation with “B” temperature rise, tropicalized and climate proof with a minimum electrical protection of IP55. The motors are specifically designed for crane applications for use in aggressive environments, without the need for anti-condensation heaters.

  • Other important factors include the stranding and construction of the wire rope. Stranding in this context considering the number of strands per wire rope and the number of wires per strand. For example if there is an 8 strand wire rope with 19 wires per strand then the wire has a 8 x 19 stranding.
  • The wire rope hoists also differs when it comes to the lay. The lay of the wire rope can be right regular or even right Lang.
  • Depending on the application of the electric rope hoist you may want to check the grade or tensile strength of the wire rope. The higher the strength of the wire rope, the higher the grade. High grade ones are often used on high rises. These may also be useful in high speed rope hoisting conditions.
  • The breaking load can be found on the cross nameplate. The breaking load can range from several values; for e.g. it could be 6550 kg or 14500 pounds.

How to use an electric  wire rope hoist

Electric  wire rope hoistare composed of a electric motors, Gearboxes, Wire rope  drum with wire rope  guides, electric panel and large wire wire rope  connected to a hook.Electric  wire rope hoistsare used to carry large objects weighing between 500 Kgs and 20 tons in various conditions like severe heat while welding, over the burners and furnaces or in acidic atmosphere.

  • Voltage Check: Check to make sure the voltage of the electric  wire rope hoist and the motor correspond with the voltage of the power supply you plan to use. Connect the rope hoist to the power supply only if the voltage will support it. Voltage is proportional to the speed of the rope hoist. Even in case of minor difference the speed obtained will be different than mentioned in the manual.
  • Check the lubrication:Make sure the gearboxes are filled up to the mark by recommended oil i nrope hoist and the end carriages of theEOT Crane.
  • Test buttons:Test your control switches before your electric rope hoist is carrying a load. Test your emergency stop button by pressing it, and making sure the wire rope hoistceases movement. You can release the emergency stop button by turning it to the left as shown over the switch.

  • Check Cross Travel Motion:Press the second set of arrows on your control switch to move the crane to the right or to the left. Check the cross travel limit switches working by taking the rope hoist to the extreme of the monorail or the Crane Bridge.
  • Check the Crane Motion:Press the third set of arrows on your control switch to move the crane horizontally. Check the cross travel limit switches working by taking the crane to the extreme of the gantry rails.
  • Trial run with the load:Press the down arrow in the first set of arrows on your control switch to lower the crane. When your hook has been attached to yourload, you can press the up arrow to lift the load. Use the second and third sets of arrows to direct the load to its destination.

Maintenance of Wire Rope hoists
