Hydraulic press safety catcher K series

hydraulic for compressive load

Safety Catchers are used where personal protection and accident prevention must be provided against failure of lifting members in an area where loads or tools are raised. Protection, for example, if a hydraulic or pneumatic pressure system fails, or if a rope, chain, belt, or toothed drive breaks. The SITEMA Safety Catcher will prevent the load from crashing down at any position of ascent; ratchless, mechanically safe and absolutely reliable. Because of its "self-intensifying clamp" operating principle, a safety level is achieved that is unsurpassed by any technological alternative. Load direction compressive (to mounting surface) General information, particularly regarding purpose, function, choosing the right type, attachment and control is provided in "Technical Information TI-A10". Further important practical advice is given in "Operating Manual BA-A11”. O M is the admissible load the mass to be secured exerts on the Safety Catcher. The holding (braking) force for dry or hydraulic-oil wetted rods is not less than 2 x M but will not exceed 3.5 x M. © The necessary pressure to keep the clampmg released is 40 bar. In case a spring base is installed. the required pressure for releasing without lifting is 60 bar. see “Techmcal Data Sheet TI-A20'. The admissible operating pressure ts 250 bar. © As supplied. pressure port LL is plugged by a plug screw. It may be used alternatively to pressure port L and is useful for filling / air-bleeding. We recommend to install an auto-bleeder at port LL (or L) as descnbed in “Technical Information TI-Z10". © Hydraulic operating volume
