As a former hoist-man in one of the deepest shafts in the western hemisphere , Man speed was limited to 1500 fpm, skipping speed was 2500fpm. this was on a double drum hoist that had 6000 hp. each drum had almost 8000 ft of cable and one foot of cable weighs 5 pounds. speed was set for several different reasons ,one being wear and tear on the equipment.
The Hesketh shaft at Chatterley Whitfield Colliery in North Staffordshire , UK , had a conical drum so that even though the engine speed remained constant the cage speed varied as the rope was released from different diameter places on the drum.
Leinster Australian Nickel Perseverance Shaft 1200m Actual lowest level I worked to was 1000m. Pumps & what not below. 18 meters per second Skip ( 60 foot per second) at 18 tons each, 1 up 1 down. Man Cage 13 Meters (40 foot) Per Second. Clutch Drums. 5 Megawat Power.
Used to be at Hem Heath latterly known as Trentham. The shaft ride was 1062 m with a tower mounted Kopie. This was a very bumpy day noise ride by comparison. At change of shift the four deck cage could hold 100 men. when in material it ran at 42ft/s (13m/s). In man riding it was 19ft/s (about 5.5m/s) used take about 4 min. There were multiple insets, so if you take the time it took to load the men, you would be in the cage for a good 15 minutes. As deputy manager services I personally didn’t appreciate going at the reduced speed, sometimes a lot slower than the max speed, where you could very nearly count the courses in the brickwork. You have more pressing things to do than spend 20 minutes in the cage.
In the U.K. The cage was wound up slightly higher the the resting position so that the keps would lock in position under the bottom of it. The keps were safety devices that prevented the cage from travelling back down the shaft by accident whilst men or coal tubs were being unloaded. Once the keps were in position, the cage would lowered slightly onto them.

Different cages than the British cages, we had lots of air holes all round the cage, and where’s there tokens to ride the cage.
This was part of my life for 9 and a half years on Western Deep Levels the deepest mine in the world.❤😮😮
that is one of the coolest elevators Ive ever seen on a verual video
Memories of my miner days at WDL... Then I became the hoist driver! Now I'm retired after a 4 day ordeal underground after a seismic shift...
these things go fast. i can barely stand the elevator at the Montreal embassy that went like 4 m/s.
God bless you
I didn't know that Santa's 🎅 base was underground.
Red overall is on this mine reserved for mine technicians and foremans
May you give technical details of guide and guide shoe system? And why on the door side?
Так они же на поверхность летят, а я так всю жизнь вниз.
I do this in canada. Pay is low, 19 bucks an hour
That will be scary
Ill be shitting on myself i cant go up 10 flight in elevator let alone 500m 😮
The winding engine driver is a noobie isn't he? Looks like he missed the mark slightly when coming up.

I could land a 10-ton load within an inch +/- at 7000 ft.
well that video has been stabilized to hell and back
Camera on the hardhat, works fine to get it more stable
@@christianboer9392 well software seems to be "the way to go" but I'm not convinced.
Never been on one with the guids in from of you always on the side of skip
ever listen to this video in surroound sound as they head to to surface
Careful the dwarves might live at the old dwarf mine dwarves like to dig dig dig dig dig dig sining their dig songs as they find treture
No thanks..........
I'll stay topside..!
Somebody must do it - instead of all other surface peoples ;-)
