MAYR drive technology has released ROBA for chain hoists safety.
The supplier says the ROBA features two separate DC injection brakes and complies with BVG safety standards.
Mayr says that chain hoists complying with BGV-D8 can only be used to lift loads during installation and dismantling of stage assemblies. During any such work, there must be no one under the load. After lifting, the load must be secured and the chain slackened. This type of chain hoist usually has only one brake, so it is not authorised for holding loads or scenery changes. The motor is only used again during dismantling. This is still the most common use of electric chain hoists in show applications.
The new ROBA-secustop from Mayr drive technology is currently available in three sizes with braking torque ranging from 2 x 4 Nm to 2 x 16 Nm.
Its compact, closed design makes it easy to handle and fit. The working clearance is preset and does not require any subsequent adjustment. This means that malfunctions due to misuse or incorrect adjustment are excluded by construction.
ROBA-secustop brakes feature integrated soundproofing to reduce operating noise. To ensure maximum operating safety and reliability, each brake undergoes full factory inspection after assembly and prior to delivery. ROBA secustop brakes are practically maintenance-free. Maintenance work is limited to inspection of the friction linings, which are extremely hardwearing and have a long service life.
Safety brakes in the ROBA-secustop series comply with the guidelines set out in the BGV-D8 Plus and BGV-C1 standards.
