position with no need to employ brake mechanism or other locking systems.
6. Hand-operated screw jack by hand wheel or crank handle, or electric driven screw jack
by 3-phase or single phase motor or gear reduction motor.
7. No standard lead screw travel length, all lead screw travel length is processed
according customers requirements. Maximum permissible 300mm travel length.
8. Lead screw end fittings include top plate, clevis end, plain end and threaded end.
9. Individually or multiple screw jack lift system arrangements are available.

Micro-Miniature Screw Jacks Applications
Micro-miniature screw jacks matching mini bevel gearboxes with parts are composed of
small screw jacks lifting system, which widely used in beverage can conveyor systems
height adjustment and beverage can washing area of the production line, saving
man-hours and lowering the down time, crucial for increasing output and are extremely
pleased with the recent financial benefits. Prior to the upgrade when the can washer area
on each line required to be changed to accommodate a run taller or shorter cans the
conversion would be completed manually. Small screw jack lifting systems is utilized
several stages for washing and blow drying the cans. Suitable for lifting height adjustment
and washing in aluminium can production lines, magnetic conveying systems, steel can
line, aluminium can line, food can line, upgrade fill and packaging line, conversion steel
aluminum can line, bottle conveyor systems, case and pallet conveyor systems.
