Answer 5

Cogs with drop bars Hydraulic disc on bullwheel

Answer 6

24 volt AC system, if the system has a break the chair shuts down. Brittle Bars or cards are plastic with a wire running around them. If the haul rope hits a card it breaks the card and the circuit. Card failure can be overridden but only to evacuate the chair. Cards must be replaced if broken. Located above the sheave train and in the rope catcher.

Answer 7

Mounted btw 1&2 sheaves on uphill and downhill sides of each tower the RD uses a laser over the haul rope. Any change in position of the haul rope by as little as a few mm will change the Reflected signal of the laser which indicates an impending Deropement, the lift shuts down. The RD can be reset in the control room.

Answer 8

The fork is a heavy gauge wire covered with rubber. When a haul rope Deropes, the rubber rubs off causing a short that in turn shows as a tower fault and the chair shuts down.

Answer 9

Mounted to the outside of the sheave train ahead of the rope catcher, the tower switch has lever the haul rope will hit during a Deropement. The switch shuts down the chair

Answer 10

On towers that allow the sheave train to rotate, a plug is installed in the assembly. In the event of a Deropement the sheave train rotates and the plug is unplugged shuting down the chair. The cup is protection against UV Rays corroding the switch.

Answer 11

6 outer metal braids wound in right handed twist surrounding a hemp or plastic core. The core allows flexibility for the haul rope to go around the bull wheel. As the core breaks down from compression and tension on the wire rope the diameter of the haul rope decreases. Annual checks for stretch and changes in diameter.

Answer 12

Actual weights, block of reinforced concrete. Suspended by cables to the bull wheel carriage. The carriage Moves as weight in the chair changes and for thermal expansion. Hydraulic pneumatic tensioning rams apply hydraulic pressure to the bull wheel carriage, a charge of nitrogen gas allows for dynamic tensioning while the lift is operational.

Answer 13

For actual weights there are sensors front and back that limit the movement of the bull wheel carriage, these can be repositioned as needed. For Hydrolic systems the piston can add or remove tension as needed. The sensors also act as a Deropement shut down device.
