Mechanical jack is powered by human through screw pair drive, screw rod or nut sleeve as the jacking parts. Common screw jack rely on screw self-locking effect by supporting weight, simple structure, but the transmission efficiency is low, return slowly.Lower screw jack without self-locking effect, equipped with brakes.Relax brakes, can be self-rapid decline in weight, shorten turnaround times, but this jack more complex structures. Jackscrew long-term support heavy loads, max weight reached 100 tons, used widely. After the bottom is mounted horizontal screw rod,the machine can make the weight for the small distance traversed.
