4 post lifts are commonly used in shops, inspection bays and heavy duty service facilities. They provide a simple way to raise a vehicle up to the frame level, but often do not lift the wheels off of the surface of the lift. Bridge jacks are a great tool to provide the additional lift needed for most repairs.A bridge jack is used between the runways of a 4-post lift. It allows for lifting the frame or axle of a vehicle. Perfect for working on wheels, brakes and suspension. Make sure to choose the correct size for easy service in your shop. https://standesign.ca/how-to-choose-the-right-bridge-jack-for-your-4-post-lift/ READ MORE
