Tailor-made industrial gear unit solution for heavy loads

Hoists often feature parallel-shaft gear units in which the rope drum and motor are arranged on the same side of the gear unit. Compact universal drives therefore often have to be oversized in terms of the torque, as the center distance between the input and output shafts is insufficient.

The new industrial gear unit series X..e/HC originates from the established X series from SEW-EURODRIVE and has an larger center distance.

This gives the crane designer crucial advantages when designing the system:

• Optimized choice of gearbox size with a reduced gear unit weight and, at the same time, sufficient center distance.
• Lower investment costs for the drive
• Savings in terms of materials and resources in the steel construction of the crane due to the weight reduction on the trolley

Reducing the total mass to be moved in this way, means that additional savings in terms of energy consumption can also be made. To increase this effect still further, the travel drives can also be made smaller if required.

Not only optimal installation, but also optimal use and maintenance. Here, too, the X..e/HC application series with its options is uncomplicated in use and easy to maintain.

Perfect solution for heavy radial loads

To absorb the radial loads from the wire rope tension, the gear unit is equipped with a reinforced solid shaft and reinforced bearings as standard. Depending on the system design, the drives are also available with hollow shafts for connecting to the application. In addition, foot-mounted design and torque arm variants are available to support the torque.

Special calculation programs enable configuration for a defined service life, e.g. with FEM-typical load spectra and crane ratings. Additional customer specifications in terms of safety values and application factors can also be included in the calculation.
