When starting up the machine or system on which screw jacks are installed, it is necessary to lubricate the lifting screw and remove, if present, foreign bodies and impurities of various kinds (poor, shavings). The electrical end-of-stroke devices (if present) of the system to be handled must be carefully checked to avoid the mechanical end-of-stroke of the jack itself. It is advisable, where possible, to start the machine or system with the load and proceed to the test in steps under normal operating conditions and the desired load. Technical details Description The mechanical screw jack is a device which transforms an input rotating movement in an output linear movement. It can be used singularly or in multiple combination by shafting, coupling and bevel gear units. It can be manually or motor powered, by electric motor DC or AC and also by hydraulic motor. Use They are used to align, to move, and to set of every kind of load.
