Different Types of Automotive Lifts Los Angeles
by Rossalie Limon Content WriterLifts
Automotive lifts Los Angeles makes the technician’s work
much easier. The vehicle can be raised so almost any under-vehicle
repair can be easily accessed and accomplished. The entry-level
technician will use a lift to change oil and inspect or replace tires.
Single Posts, Double Posts
Single-post
lifts are older types of lifts. The hydraulic cylinder is buried in a
floor cavity. The lift arms and the top of the cylinder present a
blockage to an otherwise smooth floor (Figure 3-92). In addition, many
of the under-vehicle components like the transmission and exhaust system
are blocked by the arms when the vehicle is raised. The floorboard and
exhaust can also be damaged if the lift arms and pads are not positioned
correctly. There is usually only one safety lock positioned at the
lifts full extension. Any position between completely down or completely
up relies on the hydraulic and air control valves to hold the vehicle
in place. The double-post lift is also known as the “above-ground lift".
It is designed to lift a vehicle and allow the technician to perform
almost any repairs needed under the car. Many lifts of this type have
the crossover between the two posts at the top. This provides a clear
work area under the vehicle. Most lifts of this type use two equalizing
hydraulic cylinders to raise the vehicle. Cables or flat chains run over
pulleys and attach to each cylinder, ensuring that the vehicle is
lifted evenly. There are locks at different heights so the vehicle can
be safely locked in place at several working heights.
Scissors and Drive-Ons
Scissor
lifts are best used for brake or tire service. They fit under the
vehicle and have limited height. As such, there is almost no room to
work under the vehicle. Newer scissor lifts, however, are designed to
allow full under car repairs and are commonly- fitted with slide plates
at the rear and turntables at the front for wheel alignment. This newer Automotive lifts Los Angeles
can accommodate brake repair, but it may be awkward to use because of
the runway width. Drive-on lifts allow the technician full access to
under-vehicle components. Unless equipped with secondary jacks, the
vehicle rests on its tires for the duration of the repairs. Drive-on
lifts with secondary jacks are generally used for alignment. The vehicle
can rest on its tires for alignment or the axles can be raised for
access to the wheel and brake assembly used to probe the conductor. The
test light will indicate voltage, but not the amount. If voltage is
present, the lamp will light. It is used on heavy current circuits like
the headlight and cooling fan motors.
