China Mechanical Jack Manufacturers, Suppliers, Factory

Shanghai Yiying Crane Machinery Company serves as a wholesaler specializing in Mechanical jacks, a fundamental lifting equipment primarily utilized for tasks with a limited lifting height (less than 1m). These Mechanical jacks find their main applications in factories, mines, transportation sectors, specifically for vehicle repairs, and various lifting and support tasks. Their construction embodies traits of lightness, sturdiness, flexibility, and reliability, enabling easy operation by a single person. Crafted from premium-grade materials, these jacks guarantee superior quality and an extended service life.

Operating on mechanical principles, the Mechanical jack functions by pulling the handle back and forth, engaging the pawl to rotate the ratchet gear within the gap. This rotational movement of the small bevel gear propels the larger bevel gear, in turn rotating the lifting screw and elevating or lowering the lifting sleeve, achieving the desired lifting force.

Safety is paramount when using Mechanical jacks. It's essential to inspect all components for proper functionality and ensure clean oil before use. Avoid using the jack when safety bolts or critical parts exhibit damage or significant wear, preventing risks. Proper placement on a flat and robust surface, using a wooden pad for leveling, and ensuring perpendicular positioning to the load surface are vital. Moreover, adding a non-slip cushion between the jack and the heavy object's contact surface is crucial. Overloading, discontinuing handles, or exceeding the recommended number of operators should be strictly avoided.

Additional precautions include barring anyone from standing in front of the safety bolt during use and employing safety cushions beneath rising loads. Proper securing of lifted objects and ensuring the lifting speed and force uniformity among multiple jacks is crucial. When using multiple jacks simultaneously, ensure the total lifting capacity is twice the load to maintain safety standards. The Mechanical Jack for Car, being one type of manual lifting tool, operates with a compact structure, utilizing the rocker's swing to rotate the pinion, driving the screw to lift or lower weights. It's applicable in railway vehicle maintenance, mining, construction engineering support, and general heavy object lifting and lowering tasks.
