Hydraulic wedges, otherwise known as flange spreaders or lifting wedges, are used to lift heavy loads or to separate parts of a construction from one another. The shape of the hydraulic wedge make it possible to use it with a minimal insertion space (5 to 10 mm). There are hydraulic (lifting) wedges that only lift vertically and wedges that can be used in all positions. Most hydraulic wedges are lightweight and compact and can therefore be used in small spaces where it is not possible to use other lifting mechanisms.
Wedge for vertical lifting
The Holmatro wedge for vertical lifting has a special construction enables a perfectly straight lifting movement, which prevents the load from tilting. Very suitable for lifting objects with a limited insertion space. Hydraulic vertical wedges are used for various applications such as lifting machines, spreading flanges, dismantling and assembly, and adjustment and alignment.
The lifting wedge is supplied with a safety block, step block, grease pistol, Molykote® grease cartridge, and plastic storage box. The mechanical lifting plate retracts automatically and needs a minimum insertion space of 9 mm.
Lifting loads from a flat surface
Holmatro's hydraulic wedges have been developed to lift a load from a flat surface that has a minimal insertion space. They create an opening from which to start in spaces other tools cannot get to. This makes the spreading wedges suitable for many different applications such as lifting machines, spreading flanges, dismantling and assembly, adjustment and alignment.
Hydraulic spreading wedges or flange spreaders are designed to separate flanges without damaging them or the spread arm. Flange spreaders are used in particular for maintenance work. It is also possible to use several spread wedges next to one another in order to spread the force.
