ROBA®-secustop – Safety brakes for chain hoists in stage technology
ROBA®-secustop: the perfect safety brake for electric chain hoists in event and stage technology.<br>
When using a chain hoist according to BGV-D8, loads must only be moved for the assembly and disassembly of carrier constructions. Moreover, no people are allowed to stand under the load. After lifting the load, it must be secured and the chain must be relieved. This procedure is also called “hanging dead”. Normally, this kind of hoist is only equipped with one brake and is therefore not approved for load-holding or for stage utilisation. The motor is not used again until disassembly. This still is the most common application of electric chain hoists in event technology.
In order to comply with the BGV-D8 Plus or even BGV-C1 standards, chain hoists must be equipped, among other things, with two independent DC brakes. The ROBA®-secustop brake by mayr® power transmission is a double brake, which fits these demands perfectly as it was developed and tailored specially for this purpose. Currently, this Type series includes three sizes with a braking torque range from 2 x 4 Nm up to 2 x 16 Nm.
The compact and enclosed design guarantees easy handling and installation. The working air gap is set and does not require re-adjustment. This means that malfunctions due to operating and adjustment errors are already ruled out constructively. The ROBA®-secustop is equipped with an integrated damping unit for the reduction of switching noises. Before delivery, every brake is subject to a 100 % inspection in assembled state at the place of manufacture in order to guarantee the highest operational safety and reliability. The stage brake is mainly maintenance-free. Maintenance work is limited to inspection of the friction linings, which are extremely wear-resistant and have a very long service life.
Electric chain hoists according to BGV-D8 Plus are, in contrast to hoists according to BGV-D8, also approved for load-holding. This makes the time-consuming “hanging dead” procedure unnecessary. Standing under moved loads and stage utilisation are also not allowed for these hoists. However, people are allowed to stand under the lifted and stopped loads.
Electric chain hoists according to BGV-C1 comply with the highest safety requirements. These so-called point hoists are approved for moving loads even when people stand underneath. This is valid for both assembly and disassembly work as well as for stage utilisation during shows and events.
mayr® power transmission offers a wide range of brakes for stage-technological installations. The ROBA®-secustop, an extremely economic safety brake for electric chain hoists and hoisting devices, is the perfect addition to this product range.
