Hydraulic jack, also known as a "hydraulic jack" or "bakim jack." This type of jack is used to lift heavy loads, such as vehicles (cars and trucks), to facilitate maintenance work or tire changes. Mechanism of operation: The hydraulic jack works using hydraulic power (pressurized fluids) to create a large lifting force. This is done through a hydraulic piston that allows lifting weights of up to 100 tons or more in some types. Usage: Placing the jack: The jack is placed under the designated support point for lifting on the vehicle's chassis, ensuring it is stable on a level and solid surface. Lifting: A special lever (not shown in the picture) is used to pump the hydraulic fluid and slowly raise the vehicle to the desired height. Safety: After lifting, it is always recommended to use additional safety supports (stands) to ensure load stability and prevent any slippage before starting work under the vehicle. Note: When working under lifted vehicles, all safety precautions must be taken and appropriate support equipment must be used to avoid accidents and injuries.
