4t Electric jacks are designed for convenience and safety. The electric motor drives the jack to lift and lower the load. The motor's operation is controlled through a switch, which allows for precise load management. Electric jacks have features such as overload protection, automatic shutoff, and built-in safety valves. The electric jack is ideal for frequent lifting tasks, heavy loads, and applications where safety and precision are paramount.
4t Floor Jack
4t floor jacks are manually operated and have a wheeled frame that allows them to roll under the load. The operator uses a lever to operate the hydraulic pump to lift the load. Floor jacks are versatile and suitable for various tasks, including automotive jacking and equipment lifting. The design of the floor jack allows for lifting loads at low clearance, and its stability makes it suitable for lifting heavy loads.
4t Rail Jack
4t rail jacks are designed for lifting and supporting railway vehicles. The hydraulic or mechanical rail jack lifts the vehicle by inserting the jack under the vehicle's lifting points. The rail jack has safety features such as locking mechanisms to prevent accidents. Rail jacks are portable and can be used in various railway lines.
4t Transmission jack
4t transmission jacks are designed to lift and support heavy components, especially during maintenance and installation. The transmission jack has adjustable saddles and adapters that hold the transmission safely. The hydraulic system ensures smooth and controlled lifting, making it easy to align the transmission with the engine during installation. The transmission jack is an essential tool for mechanics and professionals who handle automotive maintenance and repair.
