Purpose of Car Ramps
To lift up a car efficiently and quickly so the mechanic can fix the car
1 of 5
The hydraulic ramps work in the following manner.....
1) Electricity powered through the national grid - single or 3 phase 240V 2) Power fed through isolation switch to a safety mechanism which allows the system to be isolated to allow electrical maintainance
2 of 5
Subsystems in the car ramp
electricomechanical device -> drives a rotary gear -> provides hydraulic pressure -> ramp lifted off ground
3 of 5
Cabling
In this case probably armour cabling -> cables help lift the ram as moved by cable gears - acts as a pulley system
4 of 5
Isolation Switch
Provides safety for mechanic as devise must be stationary + fixed to prevent accidents. It cuts power and prevents the ramp from descending on its own
