Cubic Lifting Gear

The cubic body type MJ and BJ combine the idea of ??turning into axial motion with the aesthetic exterior of the cubic body cube to form a functional unit, while optimally realizing the basic design of a simple and robust lifting gear design.

Advantages

• Minimizing the required components and maximizing the effectiveness of these parts
• In the smallest space relatively large lifting and adjusting forces can be realized
• Guide the spindle through housing given
• The cubic housing design makes it easy to attach to existing construction elements

The MJ / BJ gearboxes are available in 11 sizes in basic and running nut versions. Depending on the size, they can start with a payload of 2.5 kN and lift up to 500 kN.

Highly Integrated Position Encoder

GROB developed an improved position sensor in 2010. This was first introduced to the public at the MOTEK 2010. This encoder has the advantage that only the actual movement is detected after the worm shaft and z. B. by counter up and down can be counted. There are at least 2 sensors for determining the direction of rotation. By means of the evaluation unit, a limit switch function can also be ensured. Either the signals are evaluated by means of our own control (customer side) or displayed by the evaluation unit offered by GROB.

Our display unit also has 2 programmable outputs which can fulfill a limit switch function. The resolution is different see table. This differs in part between normal and slow translation. The encoder is available for the complete transmission series MJ0 to MJ5 and BJ1 to BJ5. This is a highly integrated solution that can be used whenever no second shaft end can be occupied, or is present.
Another advantage is that the "dead gear" between worm wheel and worm shaft has no influence on the accuracy.

Advantages

• The actual movement after the worm shaft is detected
• limit switch
• Rotation monitoring
• motion monitoring
• High integration density, therefore no assignment of the second shaft end required
