EGD, Multi-Tray Conveyors
The patented Pax EGD conveyor is an electrically driven, oscillating type conveyor that utilizes a motorized, elliptical gear drive (EGD). Utilizing elliptical gears in a sealed oil bath provides an extremely reliable drive and a high conveying speed at lower RPMs.
The EGD conveyor is currently available in three sizes, which are rated based on the total tray weight (this does not include the weight of the parts and scrap on the trays).
- EGD-50: can hold up to 50 lbs of tray weight PLUS parts
- EGD-125: can hold up to 125 lbs of tray weight PLUS parts
- EGD-250: can hold up to 250 lbs of tray weight PLUS parts
Key features of this conveyor include:
- No Air Consumptions
- Quick Snap-On Tray Design
- No Springs or dynamic seals

Features
Quick and Easy Tray Attachment
Tray brackets simply snap in place over the round portion of the crossbar without the use of tools. The machined, Acetal brackets bolt to the side of the conveyor tray can rotate on the crossbar if the tray needs to run on a slight angle.
Electrically Driven, Elliptical Geared Drive
The elliptical drive gears are bathed in oil inside of a sealed gearbox. This arrangement minimizes the reverse inertia effects that create issues for many other conveyor designs.
No Air Consumption
The EGD conveyor is electrically driven which means that it does not have the high operating costs and ongoing maintenance issues that are associated with many air-driven conveyors.

Optional, Quick Release Arm Arrangement:
To provide increased access to the press, this quick-release option allows the operator to simply lift the arm, (crossbar), off of the unit and to re-install the arm by simply placing it back on the top of the unit. No tools are required to remove or replace the arm.
T- Slot Type Mounting Brackets:
Bracket bolts to the bottom of the EGD-50 and is arranged to attach to standard T-slots. Standard brackets are based on a vertical mounting surface of 5.25”, (this is the height of the vertical plate on the bracket).
Brackets are available for different T-slot sizes and spacing as shown below, (contact Pax for detailed dimensions of the required bracket).

EGD-125: T- Slot Type Mounting Brackets (PN: EGD-125-6099-0):
Brackets mount to the bottom of the EGD unit and can be fastened inside of T-slot. Standard brackets are based on a minimum bolster thickness of 4”, a distance of 23.62” to 24” between the mounting T-slots, and standard 1” T-Slots (brackets have a 1.75” wide x 0.75” thick bar that needs to be clamped into the bottom portion of the T-slot), and the edge of the bolster must be less than 6” from the end of the press bed.
EGD-125: Shelf Type Bracket Model (PN: EGD-125-6098-0):
The shelf-type mounting bracket can be bolted to a vertical surface such as the press bed. After the bracket is properly attached, the EGD conveyor is bolted to the top of this bracket.
EGD-125: Vertical Face Mount Brackets:
These brackets are designed to bolt to the bottom of the EGD unit and to a vertical surface. The bracket design is based on the following:
- Each of the two brackets has two 0.53” diameter clearance holes for mounting bolts. These holes are located 3.25” apart.
- When brackets are mounted to the EGD conveyor, the total width of assembly is 26.7” and the distance between the mounting holes on the two brackets is 24.7”.
- Minimum height of mounting surface (bolster thickness) of 4.25”.

- The diameter of clearance holes for floor anchors is 0.44”.
- The Center distance between the above clearance holes is 26”
- Distance from floor to bottom of the tray, (when the tray is parallel to the floor and does not have wear pads attached), is 9.9”.
EGD-125 Rolling Floor Stand:
Each stand (with the EGD unit attached) can be rolled up to the press and then fastened to the press’ T-slots.

EGD-250-48 T- Slot Mounting Brackets:
Brackets are bolted to the conveyor base plate, are slid into the bolster T-slots, and large set screws are utilized to fasten the brackets in place. Once in place, bolts at the bottom of the bracket are extended outward until they push snugly against the bottom of the bolster, to increase the bracket’s support and reduce its vibration. Standard brackets are based on a bolster that is a minimum of 6” thick with standard 1” T-Slots and the brackets will mount into two separate T-slots that must be spaced 48” apart. Brackets are not available for the EGD-250-72.
EGD-250-48 Vertical Face Mounting Brackets:
Brackets are bolted to the conveyor base plate and are arranged to be bolted to a vertical surface (such as the face of a bolster plate). Brackets are not available for the EGD-250-72.
Option of Utilizing an Extruded Aluminum Cross Bar in Place of Pax’s Standard Cross Bar:
For customers who have standardized extruded aluminum type cross bars, the EGD-250 conveyors can be arranged for an extruded aluminum bar. The standard arrangement is for a 1.5” x 4.5” extrusion that has a 1.5” spacing between T-slots and a T-slot opening of 0.32”.
Trays and Tray Hardware
Trays and Tray Hardware
Conveyor Trays:
Pax can make shaker trays to your dimensions. Pax’s standard trays are made of 18 gauge, 304 rigidized stainless steel. Square mounting holes for carriage bolts for Pax’s quick-connect brackets and mounting holes for wear pads can be added to trays if locations are specified at the time of order.
Quick Connect Tray Mounting Brackets
Brackets are utilized to mount customer-supplied trays to the standard Pax crossbar. After the brackets are properly mounted to the sides of a tray, the tray can then easily and quickly be snapped in place on the crossbar. Each set includes two (2) Acetal brackets (enough for one tray) and four ¼”-20 carriage bolts with nuts and washers. The customer must mount brackets to trays as required.
Bolt-On, Tray Wear Pad Kit (P/N EGD-000-6213-0):
This wear pad is typically used on trays in which the scrap is being conveyed toward the EGD unit. With this kit, the wear pad is placed on the bottom of the conveyor tray (typically towards the end of the tray) and is held in place with bolts that go through the pad and the tray and then thread into the nut plate that is positioned on the top of the tray. These pads raise the bottom of the tray by 0.5”. Kit includes; One, 3” long x 1” wide x 0.5” thick UHMW pad with two counter sunk drilled holes, two ¼” -20 flat head screws, and one “diamond” shaped nut plate.
Weld On, Tray Wear Pad Kit, (Part #: EGD-000-6219-0):
This wear pad, which is welded to the bottom of the tray, is typically used on trays in which the scrap is being conveyed away from the EGD unit. With this kit, a bracket is welded to the bottom of the tray and the wear pad is then bolted to this bracket. This kit will raise the bottom of the tray by 1.06” (the bracket is 0.56” tall and the pad is 0.5” tall). Kit includes; One, 3” long x 1” wide x 0.5” thick UHMW pad with two counter sunk drilled holes, two ¼” -20 flat head screws, and bracket that has two tapped holes to which the wear pad is bolted.
Extensions for Tray Quick Connect Brackets:
These extensions are used to increase the height of the tray. The steel plates are attached to the tray and the tray quick-connect brackets are attached to the bottom of the plates. Each kit includes two steel plates, four carriage bolts, four washers, and four nuts for the carriage bolts. Kits are available in 1”, 2”, and 3” heights.
Tray Stop (PN EGD-000-6537):
These stops are typically used in cases where the quick connect tray brackets are prone to move on the crossbar, which can occur when the trays are not between parallels and/or a tray is irregularly shaped. The stops are designed to slide across the tube that is on the top of Pax’s standard cross. The stops can be locked in place on the tube by tightening the set screw on the top of the stop. Typically, two stops are used for each tray, (one on each side of the tray). Each of these stops is approximately 0.6” wide
