Founded in the UK in 1971, 4B has been an industry leader in developing high quality, innovative and dependable material handling components for the agricultural and industrial sectors.

A subsidiary of The Braime Group, one of the largest suppliers of material handling components in the world with associates in Europe, America and Asia as well as a network of distributors worldwide, 4B provides practical solutions for all applications at any location.

With 120 year's experience to call upon, 4B is professional in the design of new bucket elevators and conveyors and upgrades of existing machines. Its design service is free-of-charge and supported by a full guarantee.

HighEfficiencyTM elevator buckets

Exceeding the traditional limits of carrying capacity, input flow and discharge, construction material use and compacted shipping space, HighEfficiencyTM elevator buckets from 4B Components possess the following characteristics:

1. Smooth interior front faces, with no breaks, providing an efficient discharge over higher speeds

Featuring a smooth interior face and sidewalls with no breaks, HighEfficiencyTM elevator buckets deliver an efficient and unencumbered discharge over higher speeds. Other designs have angled breaks, which provide no benefit to discharge efficiency. These breaks merely copy a feature from the first sheet metal buckets introduced in the 1920s.

2. They can be mounted closely together to deliver the greatest, and thereby, most efficient throughput

The ability to be mounted extremely close together allows for the most efficient use of vertical space on the belt. Other buckets are either too deep to be mounted closely together or they require modification from their standard design, leading to additional costs.

3. A tapered bottom allows the buckets to fill and discharge efficiently

The vertical sides, wings and perpendicular bottoms of other buckets impede the flow of materials into and out of the bucket. However, the tapered bottoms HighEfficiencyTM elevator buckets from 4B Components allow the buckets to fill and discharge with maximum efficiency over higher speeds. They also create a low digging factor, which means less material resistance and degradation and fewer forces on the bucket system itself.

4. The tapered bottom allows the buckets to nest inside one another, for more efficient shipping and storage

Nesting inside one another efficiently reduces the amount of space and costs associated with shipping and storage, with nesting not possible with other bucket designs. More packing materials and space are therefore required when using these buckets.

5. Wingless sidewalls, make the design more cost efficient and thereby reduce material costs

Wingless sidewalls maximise the most efficient use and cost of materials. Other buckets have a wing or 'ear' on both sides which adds cost and weight, while offering no real functional benefit.

Key to performance

As previously stated, the HighEfficiencyTM elevator buckets feature a tapered bottom. This tapered bottom is key to the performance of the high efficiency design and is leveraged for several advantages.

It allows the buckets to be mounted closely together with a minimum of vertical spacing. This creates a 'column' of input material and generates the greatest amount throughput possible in the elevator leg system.

Close vertical spacing requires the efficient entry and exit of input materials into the elevator bucket string. The tapered bottom allows the buckets to fill and discharge from the both front from the sides.

The tapered bottom allows buckets to nest inside one another. This makes shipping and storage more efficient. Traditional buckets do not nest
and even when packaged to minimise space - it is mostly air that is being transported.

Economic freight rates

A stack of HighEfficiencyTM buckets is denser and as such, qualifies for the most economical freight rates. Additionally, they use less space in the motor trailer or ocean shipping container - thereby reducing costs even further. Once at the job site, they also occupy less floor space for storage.

By eliminating the wing seen on many traditional buckets, this material is relocated to the front, side and back walls. This is a more efficient use, placing it where it is needed for longer bucket life, including the unique Iceberg Edge front wear lip.
