Lift Operations Osha Test.

Front 1

Chair Lift

Back 1

A mechanical device that transports people from one point to another.

Front 2

Bullwheel

Back 2

Large wheel located at both the top and bottom of each chairlift. It allows the haul rope to change direction at the ends of the chair lift.

Front 3

Carriage

Back 3

Framework that holds the bullwheel. It is connected to the counterweight and travels back and forth to maintain constant tension on the haul rope. It can be located at either end of the chairlift.

Front 4

Counterweight

Back 4

Large concrete weight connected to the carriage that maintains the proper tension of the haul rope. its purpose is to compensate for varying loads on the chairlift.

Front 5

Return Terminal

Back 5

The structure opposite the drive terminal, which supports the bullwheel, that changes the direction of the haul rope.

Front 6

Carriage Limit Switch

Back 6

A switch that stops the chairlift if the carriage moves further than normal.

Front 7

Haul Rope

Back 7

A steel cable with an internal rope core. It extends around both bullwheels and is supported by the towers. The carriers are attached.

Front 8

Carrier (chair)

Back 8

A device attached to the haul rope that carries skiers. Bail types are designed with a metal framework connected to the outside edges of the chair seat.

Front 9

Tower

Back 9

Large steel tube anchored to the ground. It supports the cross arm.

Front 10

Cross Arm

Back 10

The metal framwork on top of a tower that supports the sheave train.

Front 11

Sheave

Back 11

A wheel with a rubber liner that supports or holds down the haul rope.

Front 12

Sheave Train

Back 12

A group of sheaves located at the end of a crossarm.

Front 13

Grounding Sheave

Back 13

A red sheave, located at the top or bottom station, that grounds the chairlift preventing buildup of static electricity.

Front 14

Derail Switch

Back 14

A switch that stops the chairlift if the haul rope leaves the sheaves. They are located on each sheave train on every tower.

Front 15

Drive Terminal

Back 15

The structure that houses the drive machinery, the prime mover, gearbox, brakes and the auxiliary power source. It may be located at either end of the chairlift.

Front 16

Prime Mover

Back 16

The electric motor that powers the chairlift. Usually 480 volts.

Front 17

Gearbox

Back 17

Reduces the high speed of the electric motor to a safe haul rope speed.

Front 18

Auxiliary Engine

Back 18

A diesel or gasoline motor that provides a temporary power source to a chairlift in the event of an electrical power failure.

Front 19

Service Brake

Back 19

The main brake of a chairlift. it is activated by the normal stop circuit, stop buttons, limit switches, stop gate, etc.

Front 20

High Voltage Panel

Back 20

Houses the main drive breaker switches.

Front 21

Low Voltage Panel

Back 21

Contains electrical circuits for operational control of the charilift derail and limit switches, buttons, phones, etc. It operates on 24 volts.

Front 22

Emergency Brake

Back 22

A hydraulic brake located on the flange of the bullwheel activated by pulling a red ring or pushing an emergency stop button. To be used in the event of a service brake failure or to stop a rollback.

Front 23

Button Panel

Back 23

A panel used to control the chairlift. It consists of a start, slow, fast, stop and emergency stop. Operates on 24 volts.

Front 24

Bullwheel Rollback Device

Back 24

A metal bar that automatically drops into the spokes of the bullwheel and stops the chairlift in the event of a rollback.

Front 25

Gearbox Backstop

Back 25

A "one-way" gearing mechanism inside the gearbox which automatically stops the chairlift in the event of a rollback.

Front 26

Stop Gate

Back 26

A device located at the top terminal which extends under the chair seat. It is designated to stop the chairlift in the event of a bullwheel rider.

Front 27

Grip

Back 27

A device that connects the chair to the haul rope by means of gripping the exterior of the rope.

Front 28

Match Marks

Back 28

Colored marks to show the original attachement of a grip to the haul rope. They are used to determine grip slippage.

Front 29

Hydraulic Rams

Back 29

Metal pipe that holds the bullwheel. The carriage is connected to beams and travels back and forth to maintain constant tension of the haul rope. it is located at bottom terminal of the chairlift.

Front 30

RPD

Back 30

The Rope Position Detector uses magentic sensing with the haul rope. If the haul rope falls from the sheaves it senses no haul rope and the lift is shut down.

Front 31

Tensioning Pump

Back 31

The unit that keeps the hydraulic tensioning on the lift so it can run smoothly.

Front 32

Conveyor System

Back 32

Tires hooked together by belts. This system slows the chairs down to a safe loading speed.

Front 33

LED Panels

Back 33

A panel that has LED's that indicate different faults on the lift. If there is ever a fault you can't fix by hitting your reset button, follow the lifts 1060 reporting procedure and dont touch any buttons on the backboard unless specified otherwise.

Front 34

Communication lines

Back 34

what connects the tower circuitry and communications between the two terminals.
