CIGNYS is constantly in the process of designing jacks and caster jacks to exacting specifications. Many applications simultaneously require high strength and lightweight characteristics.


Modifying current designs allows us to expedite delivery at an affordable price. During the design of critical components, our engineering team utilizes sophisticated computer software protocol such as finite element analysis (FEA).

While many of our jacks might be considered “off-the-shelf” or standard, we routinely design custom jacks to your exact specifications and needs.


CIGNYS Caster Jacks can operate vertically, horizontally (or upside down) to raise, lower, or push your load. Units requiring tension load capability are available on special application.


Robust, critical design components–Our standard inner and outer wall tube construction is among the thickest in the industry. 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 eliminated.


Automatic latch & 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 load capability– Our jacks are designed to withstand side loads resulting from uneven terrain, off-center loading, and eccentric mounting methods.


High-efficiency bevel Gearheads–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.


Our standard jacks are supplied with a resistant finish – protective phosphate and prime painted with red oxide. All hardware is zinc plated. In addition, we can provide electro less nickel plating or zinc plating. Special jacks can be manufactured with stainless steel hardware and lube fittings for specialty greases for unique applications.
