What is a Grading Beam?
- 12 May, 2022
A grading beam is a wide, flat bottomed attachment used for levelling and profiling loose aggregates or soil from pre-existing piles. It's best used when wanting to grade larger areas of aggregates that have been pre-positioned and is a beneficial attachment for landscapers and groundworkers trying to achieve a level surface before further site or ground works.
Some of the materials it's most effective with include: sand, gravel, crushed tarmac, top soil and type 1 & 2 aggregate.
Grading Beam Vs Grading Bucket
The Rhinox Grading Beam has been designed to be a wider and flatter attachment, in comparison to a Grading Bucket. It is common within the construction industry for Grading / Ditching Buckets to be used in order to level the ground. This is usually done by using the reverse / back / bottom of the bucket. Using the bucket in this way causes additional wear and reduces the lifespan, meaning that the buckets with have to be replaced more frequently than usually necessary. The Grading Beam has been developed to be used for this task instead. It has been specifically designed and developed to carry out the same action without causing damage to the attachment.
The Grading Beam is a heavy duty construction, manufactured from hardened steel to maximise the resistance and durability of the attachment. It has been designed with a Machined Edge Blade to allow for flat grading of material and Guiding Fins to enable a closer grade to curbs and objects, as well as to more accurately guide materials into place. Another key feature of the beam, is the Replaceable Headstock which allows for multiple machine pick-ups, enabling the same attachment to be used on multiple machines without the need to repurchase the same attachment. Simple unscrew the bolts and swap the headstock.

Would you recommend a Grading Beam on a Micro-Digger (0.75 Ton)?
Although, physically possible, we would not recommend fitting a grading beam on a 0.75 Ton machine. We would advice that it is up to the operators discretion.
The Grading Beam is a heavy attachment. When fitted to a 0.75 Ton Micro Digger the potential for the dipper arm to twist and become damaged is higher than if it was mounted to a Mini-Digger of 2 Ton and above. As well as this, the length that the dipper arm would be able to extent while the attachment is mounted would be reduced due to the size and weight of the beam and the strength of the digger. This therefore reduces the efficiency of the attachment on a Micro Digger.
Can the Rhinox Grading Beam be manufactured with a bolt-on cutting edge?
Manufacturing with a bolt-on edge is not possible due to the amount of surface area that would need to be covered. The Grading Beam is a large attachment - due to the heavy duty construction it is already a heavy attachment. Adding a bolt-on cutting edge would require the entire lower side of the beam to be fitted, which would increase the weight considerably more. This added weight would be unmanageable for Mini Diggers and wouldn't been seen as beneficial.
As well as the unmanageable added weight, the bolt-on edge would hang below the bottom of the beam, meaning that the lower side of the beam would no longer be a flat surface and wouldn't grade / level out materials as designed to do
