Product IntroductionAs a core safety backup facility for mine shafts (vertical shafts), this equipment is activated when the main hoisting system fails or during a mine-wide power outage. Its primary function is to operate the safety ladder (emergency/escape hoisting device), undertaking critical rescue missions and personnel evacuation.
| Primary Uses and Significance |
Emergency Escape and Rescue ◎In the event of accidents such as power outages, hoist failures, or cage jams in mines, the safety ladder serves as the final mechanical safeguard for evacuating personnel from underground. |
Personnel and Material Transport ◎During non‑production periods such as daily maintenance or equipment installation in mines, the safety ladder can also be used for the safe lifting and lowering of a small number of personnel or maintenance tools, offering greater flexibility compared to the main hoisting system. |
Safety Regulation Requirements ◎According to national regulations such as the Coal Mine Safety Regulationsand the Safety Regulations for Metal and Non‑metal Mines, vertical shafts must be equipped with a safety facility capable of lifting personnel during emergencies. The safety ladder winch system is one of the key installations that fulfills this requirement. |
