The VMK-S hoists according to BGV C1, DIN 56950:2012-05 and EN 61508 SIL 3 are notable for their innovative feature set and unusually flexible handling, whilst satisfying at all times the highest standards of safety. Particularly remarkable are the two independent, lownoise and maintenance-free brakes with air gap monitoring, a real-time load-measuring module integrated in the eyelet that ascertains the real load and from it the overload and underload values, and a thermosensor that monitors permanently the operating temperature of the motor. A friction clutch as overload protection is not required by the VMK-S hoists so that continuous force and form closure without interruption between motor and load is at all times guaranteed.
Furthermore, a dual-channel incremental encoder on the motor axis and a high-resolution 29-bit absolute encoder on the chain output axis are used. This allows exact positioning – better than +/- 1 mm – that can be replicated at all times and therefore precise target runs with the greatest repetition accuracy.
All components have been optimized for particularly quiet operation. These are, in detail, the acoustically insulated container and the narrowly calibrated parts and chains. In conjunction with V-Motion Powerpacks, VMK-S hoists can be controlled at variable speeds for way- and time-synchronous runs or else directly (hoists up to 10 m / min at 50 Hz) with the MPC 4IC1 controllers at a fixed speed. These high-speed hoists (from 10 m/min) in combination with a V-Motion Powerpack are capable of speeds ranging from 0 to 40 m / min whilst functioning as a closed-loop VMK-S II – EN 01.2016 system with full torque even during runs continuing beyond the null point (‚floating state‘) and reversal of direction without incursion of the brakes.
For optimal handling ease, the hoists are equipped with two robust handles. For the secure attachment of moving loads, rotatable and tiltable single-hole eyelets are used.
VMK-S hoists are equipped with an internal status- and test-board. This illuminates the relevant operational states and implements the testing systems required by DIN 56950 for the operating and emergency limit switches, load-measuring system and brakes. With their remarkable features, VMK-S hoists represent the elite class on the world market and are recommended for all state-of-the-art applications in locations such as in TV studios, theatres and events venues demanding maximum performance and safety combined with the widest possible bandwidth of uses.
