Mechanical Jacks (steel Jacks)
Operating Manual
The steel Jack is designed by mechanical transmission principle. Its one of the best lift tools used in repairing, 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.
