How do cable cars go around corners?
Cable cars can go around corners by two different methods. In the first, the “let-go” or “drift” curve, the grip person simply releases the cable to let the car coast around the corner. Once the car is around the corner, the cable can be taken up again.
How do cable cars turn?
The pull curve involved a series of many small pulleys holding the cable in place as it makes the turn. When the car approaches, the grip is pushed away from the pulleys and guided by a chafing bar set above and outside the pulleys, negotiates the turn.
How does gondola lift work?
Ski lift chairs, gondolas, cable cars, or t-bars are connected to the steel cable and transports the skiers up to the top. The empty chair or gondola then circles around and travels back empty to the bottom of the slope to pick up new skiers.
How do California Street cable cars work?
The California Street cars were built with grips and brakes at each end precisely so turntables would not be necessary. The gripman operates the car through a switch at the end of the line. After applying the brakes, the gripman and conductor switch places, and the cable car goes in the other direction.
How does the cable car cross the tracks?
After the Powell cable car crosses the California tracks, it reaches one of the dips in the pavement, allowing it to “take rope” (reattach to the cable). For Powell cars headed toward Market Street, this happens immediately, before they descend the steep hill to Pine Street.
How does a cable lift work on a car?
The car operator lifts up the level and the pulley in the slot raises the cable into the grip. When some cars employed a side-grip however, then a lift rod was raised using a chain, causing the cable to slide down into the side of the grip.
What are the world’s only cable car crossings?
The cable car crossing at Powell & California and Mason and Jackson are the world’s only cable car crossings. The lower cable is the Powell Street, showing that Powell Street grips must be released from the cable before passing over the California Street line.
