Also referred to as floor jacks, trolley car jacks contain a wheeled base making them easy to move underneath vehicles. They mainly use a hydraulic system which boosts efficiency by providing smooth lifting. Their low profile design means they can slide under cars with minimal ground clearance. Different types of trolley car jacks suit a variety of vehicles due to differing load bearing capacities. The adjustable saddle can be set to align with specific vehicle lifting sockets. These jacks are widely used in automotive workshops and garages and are especially useful for operations like oil changes, tire rotations, and undercarriage repairs that require stability and precision.
