The ETR251/46 equipment rack drive is a low-maintenance, purpose-designed drive for starting and closing swinging-air vents in Venlo-type greenhouses. The mixture of TR251/46 gear rack drive and aEP RW motor gearbox contributes to an optimum greenhouse weather because of accurate positioning of the air vents.

The self-supporting TR251/46 gear rack drive comprises a zinc-plated C-profile with a built-in compact equipment rack drive unit. The TR251/46 gear rack drive is installed to a greenhouse gutter using the accessory clamp-installation forks or bows.

Thanks to the apparatus reduction stage (i-2.76) and the pinion of the TR251/46 gear rack drive, the drive torque is effectively converted into a maximum rack force of 4200 N. Monitor rollers in the C-profile and information blocks ensure stable expansion and retraction of the rack. The drive shafts of the TR251/46 equipment rack drive have lengthy, flat-sided journals. This can help you match drive shafts (prefab) installed with weld/planetary gearbox sleeve couplings or chain couplings, once the house units have already been mounted. The drive shafts are locked in the couplings by the accompanying shaft retaining clips. The TR251/46 equipment rack drive is simple to maintain.

A ETR251/46 equipment rack drive with other C-profile lengths and rack lengths is on request.
