The ROYALjack50 is an adjustable screw jack with an effective height of 600mm. It has a 40mm diameter coarse rolled thread, which is inserted into the ROYALframe50 legs, each of which has a SWL of 30kN. The ROYALjack50 tube is manufactured using seamless steel tube, which has the benefit of increased tensile strength, pressure ratings and durability.
These jacks have the same load capacity as the conventional shoring jacks (48mm OD), however ROYALjack50s are lighter making them faster and easier to use and handle than the conventional shoring jacks.
The ROYALjack50 is available with three (3) styles of heads: a Double U head, which fits two (2) bearers, a Single U Head, which fits one (1) bearer, or as a flat jack. The flat jack plate has a 30mm diameter hole to allow a spigot to be inserted for a ROYAL U Head
Hat attachment to convert a flat jack into a U Head jack and also allows the ROYALdek Crown to be inserted to be used for modular aluminium slab panels.
These jacks have a long-handled nut which gives better leverage to use and turn on the coarse thread making it easier to adjust at assembly stage to the desirable height and quick to release when dismantling. The nut is manufactured from cast steel for durability and reduced hammer impacts.
The ROYALjack50 is used throughout the ROYALframe50 series, the ROYALformstage system, (modular scaffolding system) and the open-ended, 51mm OD vertical standards.
