Reduction Gearboxes

Helical bevel reduction gearboxes are used for transmitting mechanical power through ninety degrees.

Used in screw jack systems either with a hollow or solid output shaft. Ideal as the main drive for H, U and T configuration jacking systems. Also used fitted directly to screw jacks as a primary drive.

Up to 14000Nm torque transmission with gear ratios up to 1715:1.

In-line helical bevel reduction gearboxes are used for transmitting mechanical power in-line with the electric motor or input drive.

Used in screw jack systems as the primary drive or on motorised screw jacks. Ideal as the main drive for I configuration jacking systems or H, U and T configurations when connected to an additional bevel gearbox.

Up to 12000Nm torque transmission with gear ratios up to 1481:1.

Parallel Shaft Helical reduction gearboxes are used for transmitting mechanical power along drive lines parallel to the motor shaft axis.

Used in screw jack systems either with a hollow or solid output shaft. Mainly used as the main drive for H, U and T configuration jacking systems due to space restrictions. Also used fitted directly to screw jacks as a primary drive.

Up to 14000Nm torque transmission with gear ratios up to 2099:1.

Worm gearboxes are used for transmitting mechanical power at right angles to the electric motor or input drive.

Worm gearboxes are less efficient than the equivalent helical bevel gearbox, however they can offer high to very high gear ratios in a small space. Used in screw jack systems as the primary drive or on motorised screw jacks. Normally used as the main drive for H, U or T configuration jacking systems. Also used on I-configurations though usually mounted to the first screw jack in the line. Worm gearboxes can be mounted to screw jacks via an adaptor where a high reduction is required for slow moving applications.

Up to 71000Nm torque transmission with gear ratios up to 10000:1.
