Lifting Solutions
USA Industrial Crank Tables configurations include jack screw mechanisms, cast iron crank handles, couplings, linking bar, solid hardwood top with metal trim or steel top, steel frames, guides, and drawer options.
We only supply a complete lifting solutions like jack screw mechanisms, cast iron crank handles, couplings and connecting shafts. Following your design technical parameters like table sizes, loads, lift height etc, our engineers will select the correct models of above products. At present, we offered 1 ton jack screw mechanisms, 2 ton jack screw mechanisms, 3 ton jack screw mechanisms and 5 ton jack screw mechanisms for table building customers.
We supply screw jack with self lock acme screw, no need brake mechanism or others locking system, and also precisely positioning.
All screw jacks lift height (stroke) is processed following your requirements. No finished lifting screw, following your required lift height, we will calculate the lifting screw total length, then start to produce the lifting screw to match the corresponding jack.
Screw jacks have uniform travel speed features. Normally, each model of screw jacks has two gear reduction ratios, they are H high speed and L low speed. High speed travels about 1mm per revolution of hand wheel, low speed travels about 0.25mm per revolution of hand wheel. So the table lift height equal to the turns multiply by the travels per revolution.
The guiding support is recommended. Because screw jacks are designed primarily to raise and lower axial loads and any side loads should be avoided. The jacks will withstand some side loads, depending on the diameter of the lifting screw and the extended length of the lifting screw. For most of table sizes is not small, when put the loads on the table, the loads is not uniform on the lifting screw, where side loads are present, the loads should be guided and the guides, rather than the screw jacks, should take the side loads - particularly when long raises are involved. Even a small side load on the table, which can exert great force on the screw jacks housings and bearings and increase the operating torque and reduce the life expectancy.
