A floor jack, also known as a trolly jack, is a versatile piece of equipment used for raising a vehicle from the ground to perform maintenance. It has an elongated, low-profile body, which slides under the side of the car. It has a long handle, which provides good leverage and four wheels, allowing it to move around easily.

Capacity

A jack needs to have the correct weight capacity for the vehicle that you want to lift. Standard floor jacks are designed for professional use and usually have a 2 or 3-ton capacity. This is sufficient for most family cars and SUVs. However, some vans and trucks may be much heavier.

Height

The maximum and minimum heights are also critical. The minimum height is how low the jack can adjust to the floor, ensuring it is suitable for vehicles that sit close to the ground. The maximum height is how far the jack will extend and should be high enough to lift taller vehicles like SUVs and trucks.

Wheels

The wheels are the only part of a floor jack that comes into contact with the ground, and therefore, they carry all the weight. Metal wheels, such as cast-iron and steel, are durable. However, they may scratch painted floors. Alternatively, Polyurethane wheels are non-marring and offer similar strength.
