OYM001 1000KG rugged Marine Jack

OYM001 1000KG rugged Marine Jack is a telescoping screw-type stabilizer jack designed for trailer and caravan tongue support, boat trailer parking, and light marine equipment leveling applications. With a 1000 Ton rated load and a 10-foot travel range on 50.5/44.5 mm tube sections, it covers the majority of recreational trailer stabilization requirements in a single tool.
The telescoping outer and inner tubes are manufactured from galvanized steel that resists the salt-spray corrosion inherent in marine and coastal environments—a critical material choice for equipment that may sit stationary for extended periods between uses while exposed to humid, salty air. The galvanized coating is applied after tube fabrication to ensure complete coverage of cut edges and weld seams.
The drive mechanism uses a welded-plate hand-crank that folds flat when not in operation, reducing the risk of snagging or catching during transport. The drive is mounted concentrically with the tube axis, applying a straight vertical load to the screw thread rather than an eccentric moment that could cause galling or binding under heavy tongue weights.
A swivel foot plate at the base allows the jack to accommodate slight surface irregularities—dock timbers, gravel, and uneven concrete—without requiring the operator to level the trailer before deploying the stabilizer. This swivel is limited in travel to prevent the foot from folding under load.
For small boat owners, caravan users, and trailer enthusiasts, the OYM001 provides a dependable, matching the factory-specified tongue capacity of most recreational trailers in this weight class.
