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.
Technical Data Sheet TI-A14
Safety Catchers sériés KRP/T (with DGUV approval)
Load direction tensile (to mounting surface)
General information, particularly regarding purpose, function, choosing the right type, attachment and control is provided in “Technical Information TI-A10".
SITEMA flanges, which are required for the attachment, are listed in “Technical Data Sheet TI-A30". Further important practical advice is given in “Operating Manual BA-A12".
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.
O The necessary pressure to keep the clamping released is 4 bar. In case a spring base is installed. the required pressure for releasing without lifting ts 6 bar. see “Techmcal Data Sheet TI-A21 The admissible operating pressure is 10 bar.
O Pneumatic operating volume
O Proximity switch holders are provided for standard inductive prox-imity switches (M12x1. nominal switching distance 2 mm. flush mountable.
