About Car Ramps
Car ramps are used to gain access to the underside of a vehicle, generally so that that vehicle can be maintained. Usually comprising a metal frame with a pair of runners for the front wheels of the car, car ramps can make a low-hassle, low-maintenance alternative to a regular hydraulic car jack.
To use a car ramp, the operator simply places the ramps on the floor and then either drives or tows the front of the car on to the ramps. This raises the front of the car up, allowing a mechanic to get underneath the vehicle by lying in the space between the runners. Car ramps are often used in conjunction with wheeled trolleys, which allow mechanics to slide in and out from underneath the car on their backs.
Most ?runner style? car ramps have a maximum load of two or sometimes 2.5 tonnes, making them able to cope with even large cars. However, vehicles such as minivans, off roaders or commercial vehicles may need an alternative type of ramp, as exceeding a ramp's capacity can be dangerous.
Most high-capacity ramps comprise a U-shaped frame with two prongs protruding inwards, similar to the prongs of a forklift truck. To lift a car, the operator moves the prongs all the way to the bottom of the frame, and then positions the car so that the front wheels are directly over the prongs. The mechanic can then use the ramp's controls to lift the prongs up, raising the front of the vehicle off the ground.
