In the mining of ultra-deep resources, workers need to use ultra-deep mine lifting equipment to lift minerals, in order to ensure the synchronization between ropes during the lifting process.
3 Comparing characteristics: ; Framed headgear is more durable and can handle heavier loads, making it suitable for deep mines. It has a complex design and requires more materials. A-frame headgear is simpler and lighter, making it easier to construct and maintain, but it is limited in the weight it can lift and is typically used in shallower mines.
Assisted lift devices (manipulators) are currently used in many manufacturing sectors to reduce injuries associated with manual equip-ment and materials handling. …

Mobile cranes (both truck cranes and crawler cranes) are used at surface metal and nonmetal mines for various types of applications. Mobile cranes are most frequently used for hoisting and placing parts during the assembly and maintenance of large mining machines, mine/mil facilities, and buildings. Cranes are used with a breaker ball at some
• Equipment integrity shall be maintained, supported by an equipment register. • Lifting devices and equipment shall undergo detailed/thorough examination by a competent person at least every 12 months, and at least every 6 months for equipment used to lift people. • All lifting devices and equipment shall be visually examined before use.
Common lifting tools include lifting hooks, clamps, shackles, chain slings, and rope slings. It is important to inspect lifting tools before use and not exceed their safe working load. Overhead cranes come in various types and are used to safely lift and move heavy loads over long distances in industrial facilities.
"Lifting tackle" means any chain sling, rope sling, hook, shackle, swivel, coupling, socket, clamp, tray or similar appliance, whether fixed or movable, used in connection with the raising or lowering of persons, or loads by use of lifting machines. Lifting Tools Tackles Lifting Hooks Vertical Lifting Clamp.
The application of precise, reliable and safe lifting machinery is imperative for various operational facets in mining, including maintenance and production processes, says lifting equipment ...
