The Beyceps one-hand assembly tool enables powerful and precise assembly work with a lifting force of up to 180 kg. It is suitable for both professional and DIY use. The usable range when lifting or spreading is 5 to 230 mm without the protective cap fitted to the base. Thanks to a quick, tool-free conversion, the device can also be used for clamping, with a clamping range of 170 to 390 mm. In combination with the separately available BEY-IK installation kit, the range of applications is further extended. It is operated ergonomically via a pump handle made of 2-component plastic, with separately arranged levers for fine lowering and releasing. This arrangement prevents unintentional release. The closed plastic housing protects the mechanism from dust, dirt and chips, while preventing fingers from becoming trapped. Protective caps for the stand and lifting plate are included to protect sensitive surfaces.
