Introducci\u00f3n<\/b><\/strong><\/p>\n

Replacing bowl-type elevator buckets appears straightforward at first glance \u2014 they are round, they have a base, and they attach to the elevator chain. In practice, however, the replacement process requires confirmation of three specific dimensions that are independent of the bucket’s capacity: the top opening diameter, the base mounting diameter, and the chain attachment geometry. Getting any one of these wrong results in a bucket that either does not fit the elevator chain or does not clear the elevator casing.<\/p>\n

This guide provides the complete dimensional reference for all six standard bowl-type elevator bucket sizes, explains the base diameter grouping system that governs chain compatibility, and covers the plasticiser-free food-grade option for direct-contact applications. By the end, you will have the information needed to specify a replacement order with the same precision as a drawing-confirmed industrial component.<\/p>\n

Complete Bowl-Type Elevator Bucket Specifications: All Six Sizes<\/b><\/strong><\/h2>\n

The table below provides the complete dimensional specification for all six standard bowl-type elevator bucket sizes. Note particularly the base diameter column \u2014 this is the most important dimension for chain compatibility confirmation.<\/p>\n

 <\/p>\n

Reading the dimension table: three key points<\/b><\/strong><\/h3>\n

First, within Group A (126mm base, sizes 0.8L to 3.0L), all sizes share the same base mounting configuration. Consequently, if you need to increase capacity from 1.4L to 2.0L, the change involves only the bucket itself \u2014 no modification to the chain attachment hardware is required.<\/p>\n

Second, Group B (150mm base, sizes 4.0L and 6.0L) uses a different base attachment configuration. Therefore, upgrading from a Group A size to a Group B size requires modification of the chain attachment hardware and should be confirmed with the elevator supplier before ordering.<\/p>\n

Third, the top opening diameter increases with capacity but is not directly proportional \u2014 the bowl deepens and widens simultaneously. As a result, casing clearance must be re-checked when upgrading to a larger size within the same base group, even though the base attachment is unchanged.<\/p>\n

 <\/p>\n

Section 2 \u2014 Casing Clearance Check<\/b><\/strong><\/p>\n

Confirming Casing Clearance for Your Replacement Size<\/b><\/strong><\/h2>\n

The top opening diameter of the bowl-type bucket determines whether the bucket clears the elevator casing walls during operation. On the curved sections of the C-type elevator path \u2014 where the chain changes direction around the top and bottom sprockets \u2014 the bucket sweeps an arc that is wider than the bucket’s nominal top diameter. Insufficient casing clearance at these points causes the bucket to contact the casing, producing noise, bucket wear, and eventually casing damage.<\/p>\n

How to confirm clearance before ordering<\/b><\/strong><\/h3>\n
    \n
  1. Measure the internal casing width at the narrowest point \u2014 typically at the curved transition sections at the top and bottom of the elevator<\/li>\n
  2. Subtract 20mm as a minimum clearance margin (10mm each side)<\/li>\n
  3. The result is the maximum allowable bucket top diameter. Compare to the target bucket size in the specification table above.<\/li>\n
  4. If the target size exceeds the maximum allowable diameter, step down to the next smaller size or contact us to discuss casing modification options<\/li>\n<\/ol>\n

     <\/p>\n

    For most food packaging C-type elevator installations, the casing is designed to accommodate up to the 3.0L size (239mm top diameter) without modification. Upgrading to 4.0L (260mm) or 6.0L (281mm) typically requires a casing width check and may require elevator modification.<\/p>\n

     <\/p>\n

    Section 3 \u2014 Plasticiser-Free Option<\/b><\/strong><\/p>\n

    Plasticiser-Free Food-Grade Bowl Buckets: Technical Specification<\/b><\/strong><\/h2>\n

    Standard food-grade PP bowl-type buckets meet FDA 21 CFR 177.1520 and EU Regulation 10\/2011 requirements for food contact materials. However, some food applications \u2014 particularly pharmaceutical, infant nutrition, organic certified, or products with very low migration thresholds \u2014 require a plasticiser-free formulation that provides additional assurance beyond standard food-contact certification.<\/p>\n

    What plasticisers are and why they matter<\/b><\/strong><\/h3>\n

    Plasticisers are additives used in PP moulding to improve flow characteristics during the injection moulding process. They are not required for the structural performance of the finished bucket, but they are present in the standard material formulation and will migrate into product at trace levels over time, particularly in contact with oily or fatty foods.<\/p>\n

    For most food applications, the migration levels from standard food-grade PP are within regulatory limits and pose no practical concern. Nevertheless, for applications where migration documentation must be provided to a retail buyer or regulatory authority, or where the product itself is an oil or fat (which enhances plasticiser extraction), the plasticiser-free variant provides a higher compliance ceiling.<\/p>\n
