Механическая Джек

Characteristics:: 1.Quick braking,safe and reliable. 2.Quick lift,high working efficiency. 3.Smooth transmissions,no jerks. 4.Sturdy structure,light weight. 5.High efficiency, small turning force. 6.Ergonomic design for more comfortable operation. The steel jack is designed by mechanical transmission principle. It’s one of the best lift tools used in repairing and supporting, etc. The lifting or lowering speed is controllable. Moreover, it overcomes the shortcoming of the common hydraulic jacks whose lowering height and speed is out of control when oil leaking. The top-quality all steel structure makes it safe and durable. The compact design with collapsible lever offers easy operation and simple maintenance. It has two applicable support stands. The lifting range is much bigger. Applications: To lift machines, vehicles, equipment and perfabrication parts in mechanical assembly and vehicle overhaul, and at construction sites.To lift rails in railway maintenance and repairs.To support the prop timber in mine, tunnel, bridge, concrete buildup, etc.To raise the lower positioned object before it is lifted.
