High-Performance Z-Type Elevator Buckets | Food-Grade & Industrial Solutions
Elevator Bucket -Overviem
We provide a comprehensive range of Z-type elevator buckets designed for precision material handling in food, chemical, and agricultural industries. Our buckets are engineered to meet strict hygiene standards while ensuring seamless integration with the Z-type and C-type elevator systems supplied by Chinese packaging machinery manufacturers.
As a specialist replacement parts supplier, we manufacture Z-type elevator buckets that directly replace the original components across all mainstream Chinese elevator brands — matching the mounting width, bucket profile, and attachment geometry of the original part, confirmed by technical drawing before every order.
Whether you are sourcing standard replacement buckets for a multihead weigher infeed line or specifying a custom multi-outlet configuration for a complex distribution layout, this page covers every Z-type bucket in our range.
Part of our complete bucket elevator parts range.
Core Sizes: Z-Type Elevator Bucket Sizes: 0.5L to 6L
Z-type elevator buckets are available in six standard capacity classes. Each class covers multiple mounting widths to match the specific chain pitch and frame width of your elevator.
1.8L Standard Bucket — The Most Versatile Size
The 1.8L Z-type bucket is the most widely used size in multihead weigher infeed systems across China and in export markets. Its capacity and discharge geometry are optimised for the cycle rate of 10–16 head weighers running snacks, nuts, seeds, coffee beans, and similar free-flowing granule products.
- Materials: Food-grade PP (Polypropylene) and ABS
- Surface options: Smooth (standard) or dimpled (for sticky products — reduces adhesion and ensures complete discharge)
- Mounting widths: 412mm, 416mm, 418mm, 420mm — covering the major Chinese Z-elevator frame standards
- FDA and EU 10/2011 compliant for all food-contact applications
- Optional triangular side reinforcements (Triangle Edges) for high-speed operation above 40 cycles/min
4L Heavy-Duty Bucket — High Throughput
The 4L bucket is specified where throughput requirements exceed the capacity of a 1.8L bucket, or where the product has a lower bulk density (puffed snacks, freeze-dried fruit, large nuts) that requires more volume per cycle to achieve the target fill weight.
- Materials: PP and ABS
- Surface options: Smooth or dimpled
- Standard mounting width: 420mm
- Reinforced structural geometry — handles the higher impact load of larger product pieces at full-speed discharge
6L High-Capacity Bucket — Two Profiles
The 6L bucket is available in two profiles to accommodate different machine frame widths — a critical distinction when sourcing replacements for existing elevators where the frame dimension is fixed.
- Type A (521mm width): for wide-frame Z-elevators common in grain and agricultural processing lines
- Type B (491mm width): for standard industrial frame widths
- Materials: PP standard; ABS available on request
- Application: high-volume grain, animal feed, large-format snack products
Compact Sizes — 0.5L, 1L, 1.5L
For precision applications, space-constrained layouts, or small-volume products requiring tightly controlled bucket capacity.
- 5L: pharmaceutical granules, small seeds, fine spice mixes
- 0L: standard compact lines, single-serve portion infeed
- 5L: coffee capsule filling lines, precision weigher infeed
- All compact sizes available in PP; surface options as per standard range
Technical Advantage ：Multi-Outlet Discharge Design
Standard Z-type buckets discharge product at a single point at the top of the elevator. For packaging lines with multiple weighers or filling heads receiving product from one elevator, a single discharge point creates a distribution bottleneck.
Our 2.6L and 3.8L buckets are available with multi-outlet (multiple spout) designs that allow product to be discharged at two or more points simultaneously along the top run of the elevator — eliminating the need for separate distribution conveyors between the elevator discharge and individual weigher infeeds.
2.6L Multi-Outlet Bucket
- Available widths: 198mm, 326mm, and custom widths up to 474mm
- Outlet configurations: 2-outlet and 3-outlet standard; custom positions available
- Materials: PP, ABS
- Application: dual-lane weigher infeed, parallel filling head distribution
3.8L Multi-Outlet Bucket
- Available widths: 198mm to 474mm range
- Outlet configurations: 2-outlet standard; custom available
- Materials: PP, ABS
- Application: high-throughput dual-lane distribution, confectionery multi-head systems
Retrofit value: Multi-outlet buckets are particularly valuable in retrofits where floor space does not permit additional conveyor runs. By distributing product within the bucket cycle itself, the same elevator footprint serves multiple downstream stations without structural modification.

Matching by Dimension — No Brand Required
Most Chinese Z-type elevators use one of four standardised mounting widths: 412mm, 416mm, 418mm, or 420mm. If you know your mounting width and required bucket volume, we can confirm compatibility without knowing the machine brand at all.
This covers elevators from brands that are no longer in business, unbranded OEM machines, white-label lines, and custom-built conveyors where no brand documentation exists.
Compatibility statement: Our buckets are designed to replace parts for all mainstream Chinese Z-type and C-type bucket elevator systems. By confirming the mounting width (center-to-center hole distance) and bucket volume, we guarantee a 100% dimensional fit — regardless of the original manufacturer. Drawing confirmation is issued for every order before production.
How to Confirm Compatibility in 3 Steps
- Step 1 — Measure or photograph: measure the center-to-center hole distance (mounting width) on your existing bucket, or send a photo with a ruler for scale
- Step 2 — Send to us: email the photo or four dimensions (A: hole distance, B: length, C: width, D: depth) to our technical team
- Step 3 — Receive confirmation: we issue a technical drawing showing the matching bucket specification within 24 hours — before any order is placed and at no charge

Frequently Asked Questions about Z-Type Elevator Buckets
Smooth surface buckets are the standard specification for the vast majority of dry, free-flowing products. Dimpled (textured) surface buckets are specified for products with adhesive surfaces — coated confectionery, oily nuts, gummy candies, or any product where residue accumulates at the bucket base and causes incomplete discharge. The dimpled surface increases the contact angle between the product and the bucket wall, reducing adhesion and ensuring complete discharge on every cycle.
The mounting width is the center-to-center distance between the two chain attachment holes on the bucket back. This must match your elevator’s chain pitch exactly. The easiest method: measure the hole distance on an existing bucket, or send us a photo. For Kenwei and Dahe elevators, 416mm and 420mm are the most common widths — but always confirm from the physical measurement, as the same brand may use different widths across machine generations.
No. Above 80°C, PP begins to soften and deform under load — particularly at the attachment points. For 80°C to 120°C, specify Nylon (PA). For above 120°C or CIP hot water cleaning environments, specify 304 Stainless Steel. Always confirm the peak operating temperature, not just the ambient room temperature, when selecting material
Standard sizes (1.8L, 4L, 6L in PP and ABS) are available from 100 pieces MOQ with no tooling charge — tooling exists for all standard sizes. For non-standard sizes or new profiles, a new mold is required: MOQ is 1,000 pieces with a one-time mold cost. For urgent breakdown replacement orders requiring fewer than 100 pieces, contact us directly — we maintain a small stock of the most common 1.8L sizes for fast dispatch.
Service life depends heavily on material and application. Virgin-material PP buckets in a standard food-grade multihead weigher application typically last 18–36 months under continuous two-shift operation. Signs of end-of-service: visible cracking at the attachment holes, product residue that persists after each discharge cycle, inconsistent fill weight at the weigher (indicating bucket deformation), or visible discolouration. Recycled-material buckets — a common quality issue with low-cost Chinese suppliers — may fail within 2–3 months under the same conditions.
