Screw jack operation manual, handing of accessories, Installation and Maintenance
Check the following matters before operation.
* Check lubricant: Check lubricant quantity.
* Check grease: Cheak grease of screw shaft
* Run-in operation: It is required to conduct run-in operation in order to perform full performance. Therefore, conduct run-in operation for 2-4 hours with 1/3-1/2 of rated load before starting.
* Caution on stroke: The stroke can overrun up and down in both direction within 5-20 mm. When the stroke overrun more than above, screw shaft will be stopped at the place where the stopper to be mounted on the screw shaft bump the housing stopper. But don’t try to conduct any work when the product is energized. Always turn off the power switch supply to avoid the product damage. However, screw shaft is locked then you must take off cover of output shaft. We recommended you to use the safety device such as torque limiter and others. But excessive over load to stopper may cause the products damaged.
Handing of accessories
* With bellows: The standard bellow is made from nylon tarpaulin. Unit with bellow must use if jack operation in such bad environment as outdoor or area filled dust or cutting power.
* With key for whirl stop: It is the structure that enables the screw shaft to move up and down by screw jack itself. The key is fixed to cover of output screw and the key way is in the screw shaft. After used for long period of time, its frictional force worm out, widening the gap between the break disks. When key way EPT a certain distance, excitation of the screw shaft dose no longer a ctivate its armatures, then replace parts.
* With motor: It is the type that the flange type motor is connected directly to the products by coupling. As it adopts the oil bath system in reducer part, it can move at high speed (confirm the attached instruction by motor maker)
* With bevel gear box: It is the type that the bevel gear box is connected directly to the product. As you can position input shaft at right angle to the standard input shaft direction, it is useful to connect many devices. Don’t add the over hung load on the input shaft of bevel gear side.
Installation
* Mounting base: Mounting surface must be rigid enough and secure a flat surface processed mechanically. Otherwise, vibration and noise will cause the jack damage. If mount the reducer, motor, align the product properly.
* Mounting bolt: For mounting bolt of jack, in case load force work on mounting bolt itself, use bolt of strength classification 10.9 or more.
Maintenance
* Change lubricant: For grease lubricant type, filled the grease through grease fitting. Excessive grease must removed from screw end cap cover. For oil bath type, after 50 hours of operation, change the lubricant for first time. After that, change every 6 months. Specially, for first time, unit must be drained, flushed wearing powder with light oil.
* Change screw shaft grease: The lubricant for screw shaft is grease. Change it with new grease at earlier stage. (in about one week). Wipe off old grease and coat with new grease. In addition, it is recommendable to change the grease even if idle unit for long period (more than 6 months).
* Check wear of female screw: Check the wear of female screw. Standard of changing female screw is depend on loading rate and frequency. For normal case, change the screw when maximum screw backlash reached the 1/4 of screw pitch.
* Check worm gear: Check the gear of worm wheel whether if abnormal wear appears or damaged.
