We can build Leveling Jacks to your specific requirements. Our experienced Engineering and Sales departments will help you design a jack to your exacting specifications.
Versatile- CIGNYS Leveling Jacks can operate vertically or horizontally to raise, lower or push your load. Units requiring tension load capability are available on special application.
Compact- Single package unit does away with cylinders or other space consuming arrangements.
Complete Protection of Screw and Critical Parts- By inner and outer tube enclosure. Round tubes on the 10,000, 20,000 and 30,000 lb. models assure precision fit and extreme mounting rigidity. Other models have a square tube construction. Special inner tube locks are available where side movement must be completely eliminated.
Automatic Latch and Self-Locking Design- Provides double safety against rotation of the jack screw under vibration or extreme loading conditions. No need for brakes or expensive locking devices. Automatic latch is standard in the 7,500 / 10,000 / 20,000 and 30,000 lb. models. Latch actuates when crank handle is removed from the assembly.
Side Loads- Can take side loads resulting from uneven terrain, off-center loading, and eccentric mounting methods.
Shelter Jacks- With 3:4 gear ratio on the 2,000 lb. model / 3:1 gear ratio on the 5,000 lb. models / 3.66:1 ratio on the 7,500 and 10,000 lb. models / 10:1 gear ratio on the 20,000 and 30,000 lb. models. Gear ratios 5:1 and 20:1 are also available on the 20,000 and 30,000 lb. capacity units. Gearheads have precision tapered thrust bearings, steel or bronze driveshaft bushings, large lubricant reservoir. The 500 lb. and 1,800 lb. models operate on direct screw drive.
Stowable- Solves ground clearance problems. Trunnion mount 31038 and 31020 models swing up and out of the way…..are easily attached to a trailer in the horizontal position.
Corrosion Resistant Design- All jacks are treated with protective phosphate and are prime painted with red oxide. All hardware is zinc plated.
