Selector / Sorting Grab Training
A hydraulic clamshell-style grab attachment used for sorting, grading and handling mixed material — waste, scrap, demolition debris or timber — that a bucket can't selectively pick up.
Accredited training route
- Scheme
- NPORS or CPCS attachment-specific module, delivered alongside excavator operator training
- Category
- Selector/sorting grab competence module
- Duration
- Half-day to 1 day
- Prerequisites
- Existing 360° excavator operator ticket
Outcome: Documented competence in grab control, load-swing awareness and safe operation around pedestrians and vehicles in a sorting yard
Load-chart & stability considerations
A sorting grab often carries irregular, off-centre and sometimes swinging loads — unlike a bucket's evenly distributed load, a grab full of mixed scrap or timber can shift its centre of gravity mid-lift, and this changes the excavator's effective stability during slew. We train operators to slew more slowly and deliberately with grab-handled material than they would with a bucket, and to recognise the specific risk of pedestrian and vehicle proximity in busy sorting yards.
Where we train sorting grab operators in NE Scotland
Cluster: Waste transfer stations, demolition sites, timber yards and scrap yards across Aberdeen and Aberdeenshire
- Waste transfer station and recycling yard material sorting
- Demolition site debris sorting for segregated waste streams
- Timber yard and forestry log handling and stacking
- Scrap metal yard material handling and vehicle loading
Inspection points & common failure modes
- Grab jaw pivot and hydraulic ram wear from repeated open/close cycling on abrasive or mixed material
- Rotation-mechanism wear on grabs fitted with a rotating head
- Quick-hitch pin wear compounded by the swinging, off-centre loads a grab often carries compared with a bucket
- Hydraulic hose routing wear from the grab's wider range of motion versus a fixed bucket
A finding we train out of your team
"A recurring finding in sorting yards is pedestrian pickers working within the grab's slew radius without a clearly marked and enforced exclusion zone — a particular risk given how much less predictable a grab-handled load's swing can be compared with a bucket load."
Regulations we reference
- PUWER 1998
- Waste (England and Wales) Regulations equivalent Scottish waste handling duties where relevant to segregation requirements
- LOLER 1998 (quick-hitch retention)
- CDM 2015 on demolition sites
Training on your own sorting grab
We deliver this training at your waste transfer, demolition, timber or scrap yard on your own grab attachment, because safe yard traffic management — segregating pedestrians, banksmen and vehicle movements around active grab work — is as much a part of competence as the grab control itself.
Based in Aboyne, Aberdeenshire AB34 — we mobilise across Aberdeen, Aberdeenshire and North-East Scotland.
FAQ — Selector / Sorting Grab
Is grab training different from bucket-excavator training?
It's delivered as a specific attachment module on top of an existing excavator ticket, focused on the different load-swing and yard-traffic risks a grab introduces.
Why does pedestrian exclusion matter more with a grab?
Grab-handled loads are often irregular and can shift or swing unpredictably compared with an evenly loaded bucket, making a clearly enforced exclusion zone more important.
Can training run in our live sorting yard?
Yes, and this is generally the most realistic environment, since yard traffic management is a core part of what's being assessed.
