Rack drives truss-railventilation for greenhouse

Rack drives truss-railventilation for greenhouse

EP Rack Drives (ERRD)

We offer a wide range of rack drives. Our rack drives are tailor-made for today´s needs, suitable for greenhouse operations and greenhouse compartments (blocks) of all sizes, as well as wide-open ventilation systems. Every truss-rail system requires a different rack drive, depending on the required force and transmission reduction. 

Two types of 
truss-rail systems

  1. A single truss-rail system, with a single push-pull tube. For this type of system, we can provide our RackDrive700 and Rackdrive800 models.
  2. A double truss-rail systems, which have two independently-driven push-pull tubes, one above the other. This system is used in Venlo greenhouses that are equipped with continuous air vents. For this type of system, we can provide our range of TRN rack drives.

Rack Drive
components

EP rack drives consist of two basic components:
  • A rack drive unit
  • A corresponding clamping set with drive shaft bearing

Effective transfer of force,
various models

AllEP rack drives efficiently convert drive torque into rack force. Our rack drive units are available in a powerful and a less powerful version. The less powerful version with a single-stage gear reduction converts the drive torque into more revolutions than the powerful version with a dual-stage gear reduction. The powerful version has a number of benefits:

  1. Accurately drives large ventilation bays with one motor gearbox per ventilation side (minor vent gap differences within the ventilation bay)
  2. Creates an extremely accurate ventilation system (minimal vent gap differences within the ventilation bay)


Robust drive shaft coupling

Our rack drives feature long drive shafts with long hexagonal journals. The use of these long drive shafts has increased the feed length of the couplings on the drive shaft journals. This is essential in large bays where the drive shafts expand or contract more due to temperature differences. The long journals ensure a solid connection between the drive shaft and the rack drive. 

Easy to mount thanks to universal
clamping construction

TRN rack drives easy to install

Our TRN rack drive unit is used for double truss-rail systems. Given the unit's double design and the significant forces involved, it’s essential that the rack drive unit is attached firmly to the greenhouse structure. We offer two options for this purpose: 

Easy attachment to a truss
These rack drives are fitted with bottom mounting plates and are mounted on the top beam of the truss with bolts and lock nuts.

  • Allows the rack drive to be mounted on the post without the need for drilling holes
  • Minimizes shade because the drive shafts are positioned near the gutter
  • Integrated bearing for the drive shafts of the outflow ventilation system

 

Easy to mount/remove thanks
to special drive shaft bearing

Our RackDrive700 rack drives are equipped with a bearing for supporting and guiding the drive shafts of the outflow ventilation system. Since the bearings can be opened, they can be mounted on (or removed from) the drive shafts without having to push them through the bearing first. 

Minimal, but essential,
maintenance 

We've been supplying rack drives for years now. Our attempts to reduce the number of gearboxes needed to open a particular number of air vents have one downside. The high drive torques are efficiently converted into high rack forces, making it is essential to observe the maintenance instructions for these systems. 

 

 

RackDrive ERRD710 rack drive unit for greenhouse

The RackDrive710 rack drive units with companion clamping sets and racks are low-maintenance power sources for driving truss-rail systems in greenhouses. RackDrive710 rack drives, in combination withEP RW motor gearboxes (3 rpm), contribute to an ideal climate in a greenhouse, thanks to the precise positioning of air vents.

A clamping set is used to mount the galvanized RackDrive710 rack drive unit around the greenhouse post below the gutter, with the guide block resting on the truss (lattice beam). This ensures an optimised transfer of forces to the greenhouse structure. The RackDrive710 is available with clamping blocks for posts of 50-60 mm width or clamping blocks for posts of 70-80 mm width. The rack drive unit has a rack height of 60 mm (centre of rack to top of truss).

The RackDrive710 features a single stage gear reduction (i = 2,76) and a hardened drive pinion for the rack. The drive torque is effectively converted to an outgoing rack force of maximum 5200 N (RRD710-523), 10000 N (RRD710-1003) or 13000 N (RRD710-1303). The guide block ensures stable extension and retraction of the rack. The RackDrive710 drive units are convenient to maintain, thanks to well-positioned grease nipples.

The long drive shafts of the RackDrive710 feature 23 mm hexagonal journals suited for a maximum drive torque of 400 Nm (RW240 to RW800 motor gearbox). This makes it possible to fit drive shafts (prefab) fitted with welded/sleeve couplings or chain couplings, once the rack drives have been mounted in the greenhouse. The drive shafts are locked in the couplings by the accompanying shaft retaining clips.

ETRN1000-3K/ETRN1000-5K Gear rack drives for greenhouse

The TRN1000-3K and TRN1000-5K gear rack drives with companion racks are powerful, low-maintenance power sources for driving truss-rail systems in greenhouses. The TRN1000-3K and TRN1000-5K gear rack drives, in combination with theEP RW motor gearboxes, contribute to an ideal climate in the greenhouse, thanks to the precise positioning of large numbers of air vents.

The zinc-plated TRN1000-3K and TRN1000-5K gear rack drives are clamped with bolt/locknut fastenings around the greenhouse post below the gutter, with the guide blocks resting on the truss (lattice beam). This ensures an optimized transfer of forces to the greenhouse structure. There are TRN1000-3K and TRN1000-5K rack drives for clamp mounting on posts of 80x50, 100x50, 120x50, 90x60, 100x60 and 120x60 (mm x mm). The rack drives are available with a height of 60 mm (rack heart to top of truss).

Through the use of a hardened gear reduction stage (i=2.76) with hardened pinion in the zinc-plated TRN1000-3K rack drive, the drive torque is effectively converted into a large maximum output rack force of 10000 N. The TRN1000-5K rack drives feature an extra gear reduction stage (i=4.60). This enables a maximum rack force of 10000 N to be achieved with a lower drive torque. The guide blocks ensure stable extension and retraction of the rack. The TRN1000-3K and TRN1000-5K rack drives are convenient to maintain, thanks to well-positioned grease nipples.

The drive shafts feature long, flat-sided journals. This makes it possible to fit drive shafts (prefab) fitted with weld/sleeve couplings or chain couplings, once the rack drive has been mounted in the greenhouse. The drive shafts are locked in the couplings by the accompanying shaft retaining clips. The TRN1000-3K and TRN1000-5K gear rack drives feature an integrated bearing for the drive shafts of the outflow ventilation system (for 5/4" drive shafts or link shafts 1").

ETRN520-3CK Gear rack drive for greenhouse

The TRN520-3CK gear rack drives with companion racks are purpose-designed, low-maintenance power sources for driving endwall bay truss-rail systems in greenhouses. The TRN520-3CK gear rack drives, in combination with theEP TRN520-3S/TRx1000-3S, TRN520-3KD/TRx1000-3KD and TRN520-3KC gear rack drives and RW motor gearboxes, contribute to an ideal climate in the greenhouse, thanks to the precise positioning of air vents.

The zinc-plated TRN520-3CK gear rack drives are mounted below the gutter with bolt/locknut fastenings to a gutter bracket (80x50, 100x 50) in a C-profile (50x25x7.5) attached to the post support. The C-profiles must be braced from the ridge beam of the greenhouse. This ensures an optimized transfer of forces to the greenhouse structure. The rack drives are available in rack height of 11.5 mm (rack centre to top of truss).

Through the use of a gear reduction stage (i=2.76) with hardened pinion in the zinc-plated TRN520-3CK gear rack drive, the drive torque is effectively converted into a maximum output rack force of 5200 N. The guide blocks ensure stable extension and retraction of the rack. The gear rack drives are convenient to maintain, thanks to well-positioned grease nipples.

ETRN1000-3UK/ETRN1000-5UK Gear rack drives for greenhouse

The TRN1000-3UK/TRN1000-5UK rack drives with companion racks are purpose-designed, low-maintenance power sources for driving endwall bay truss-rail systems in greenhouses. The TRN1000-3UK/TRN1000-5UK rack drives, in combination with theEP TRx1000-3K and TRx1000-5K/TRx1300-5K rack drives and RW motor gearboxes, contribute to an ideal climate in the greenhouse, thanks to the precise positioning of air vents.

The zinc-plated TRN1000-3UK/TRN1000-5UK rack drives are attached to a U-profile (60x40x3) with bolt/locknut fastenings. This U-profile is hung between gutter brackets, and must be braced from the greenhouse ridge beam. This ensures an optimized transfer of forces to the greenhouse structure. The rack house units are available with a rack height of 40 mm (from underside of U-profile to rack centre).

Through the use of a hardened gear reduction stage (i=2.76) and a hardened pinion in the TRN1000-3UK rack drives, the drive torque is effectively converted into a large maximum output rack force of 10000 N. The TRN1000-5UK rack drives feature an extra gear reduction stage (i=4.60). This combination generates a lower drive torque, with at the same time a maximum rack force of 10000 N. The guide blocks in the house units ensure stable extension and retraction of the rack. The TRN1000-3UK and TRN1000-5UK rack drives are convenient to maintain, thanks to well-positioned grease nipples.
