6859R-G9-E2P bucket elevator chain: 228.6 mm pitch, 430 kN tensile, 25.4 mm pin.
The SHINING 6859R-G9-E2P is a bucket elevator chain built for cement plants. It runs on a 228.6 mm pitch with 7.5 mm chainplates 63.5 mm deep, a 25.4 mm pin in a 44.45 mm bush, and the average tensile strength is 430 kN. The bucket fixing attachments are G-9 steel bushed/knuckle chain attachments on an offset sidebar (Renold Style O), fitted every 2 pitches (E2P), so bucket centres sit 457.2 mm apart; attachment plate dimensions are made to each customer's drawing.
On a bucket elevator the chain carries its own weight, the buckets and the material over a vertical lift, all day. The 6859R-G9-E2P is built for that duty: a heat-treated pin with a hardened bearing surface, a carburized bush and an offset sidebar (Style O) form that keeps the buckets running true on the head sprocket.
Raw Meal and Kiln Feed Elevators: lifting ground raw meal to the preheater tower.
Clinker and Cement Elevators: hot clinker and finished cement on the same pitch.
Central Chain Bucket Elevators: replacement chains for existing elevator frames.
Matched Sprockets: head and boot sprockets available from the same works.
The average tensile strength of 430 kN carries the vertical lift with a wide margin over working tension, including start-up loads with a full boot.
The 25.4 mm pin is heat-treated with a hardened bearing surface, and the 44.45 mm bush is carburized - the wear is taken at the bush, where it can be replaced.
The offset sidebar carries the bucket load through the full plate section and keeps the buckets aligned on the head sprocket.
The chain is built with G-9 steel bushed/knuckle chain attachments on an offset sidebar (Style O) every 2 pitches (E2P), one attachment plate on every second link, so bucket centres are fixed at 2 x 228.6 = 457.2 mm. The plate is 140 mm wide with 152.4 mm fixing centres and four bolt holes for the bucket back plate; other attachment patterns and spacings (E3P, E4) are made to your drawing.
Head and boot sprockets are supplied from the same works, so chain and sprocket wear together.
The table below gives the 6859R-G9-E2P bucket elevator chain: pitch, pin and bush dimensions, offset sidebar (Style O) section, bucket attachment centres and average tensile strength.
| Chain No. | Pitch (mm) | Plate thickness (mm) | Plate height (mm) | Pin diameter (mm) | Bushing OD (mm) | Bushing ID (mm) | Tensile strength (kN) |
|---|---|---|---|---|---|---|---|
| 6859R-G9-E2P | 228.6 | 7.5 | 63.5 | 25.4 | 44.45 | 25.4 | 430 |
Attachments: G-9 steel bushed/knuckle chain attachment, offset sidebar, every 2 pitches (E2P) - one four-hole attachment plate every second link, bucket centres 457.2 mm; pin and bush joints with cottered ends.
SHINING has manufactured conveyor chain and sprockets for cement plants for over twenty years, with drop forging, welding, machining and heat treatment under our own control. Every production batch is tensile-tested before shipment, and our quality system is certified to ISO 9001:2015 (46026Q00958R053) and ISO 14001:2015 (46026E00959R053).
We build to interchange. Send the OEM part number, an old link or a drawing, and we will confirm the match and reproduce it dimension-for-dimension, with sprockets and attachments cut to suit.
Standard production lead time is 60 days from receipt of the order and confirmation of the drawing. For breakdowns and planned shutdowns we can discuss an expedited slot - tell us your date and we will plan the delivery around it.
Our engineers support station and duty review, chain selection, wear and elongation analysis, maintenance planning, and genuine replacement parts. Send your conveying duty and we will size the chain for you.
Tell us your duty, your drawing or the OEM part number, and our engineers will come back with the right chain and a price. Email the sales team at sales@shiningco.com.
