DICTATOR spring rope pulleyThe ideal closing device to meet the EN 81, point 7.7.3.2 According to EN 81-1/2 point 7.7.3.2. all landing doors driven by the car door have to be equipped with an additional mechanical closing device. This has to ensure the automatic closing of the landing door when it is open, for whatever reason, and the car is outside the unlocking zone. An ideal solution to this problem represent the new models of the DICTATOR spring rope pulley with plastic casing. Due to guide grooves for the plastic cable injected in the casing and an optimized bearing of the spring in the casing, they offer a very long operational life and an optimum functioning. Using a plastic casing and a plastic cable also minimizes noise emission. Models: Spring rope pulley with hub for fixing with an 8 mm square bolt (to be procured by the customer) or a screw with square neck (DIN 603) (by customers). For this model we supply a mounting bracket (part no. 070113), see dimensioned drawing further down. Spring rope pulley with sliding hub: this prevents the possible damaging of the spring during tensioning or releasing. The spring rope pulley with sliding hub always comes together with a bracket (zinc-plated or AISI 304). Mounting on the wall or ceiling becomes much more easier when fixing the bracket to the separately available mounting plate with headless pins (part no. 070114).
