On site, when a grab comes in from the wrong angle, the material rarely behaves as expected. It shifts, slips or rolls out, even when the grip looks firm.
Approach direction is one of the most overlooked factors in how well a grab controls material during lifting and placement.
Material on demolition and sorting jobs is rarely stable. You are dealing with:
If the grab approaches from an incorrect direction, the force applied does not match how the material is sitting.
Instead of securing it, the grab disturbs it.
When the grab comes in at the wrong direction, several issues appear:
The result is not just poor control, but repeated handling.
This is where inefficiency builds quickly during material handling.
Incorrect approach direction affects more than just the grab cycle.
On site, it leads to:
Over time, this slows down the entire sorting or loading process.
When the grab is aligned with how the material is positioned, the behaviour changes immediately.
You start to see:
Each movement becomes controlled instead of reactive.
This is where selector grabs begin to deliver consistent on-site performance.
On site, control starts before the grab closes.
A more effective approach:
If the load shifts before closing, the approach direction is usually the issue.
Correcting position solves more than increasing grip force.
The common assumption is simple:
If the grab is strong enough, it will hold anything
In reality, strength alone does not create control.
Without correct approach direction, even a strong grab struggles to stabilise the load.
Experienced operators focus on positioning first, then closure.
That change in approach improves both control and speed.
Even with the right technique, setup can influence approach effectiveness.
Factors that affect control include:
Well-prepared equipment allows smoother positioning before engagement.
This is where properly set up attachments from TocDem support more precise handling on site.
Why does material slip even when the grab is closed tightly?
Because the approach direction was incorrect, causing uneven force distribution across the load.
Is top-down grabbing always a problem?
Not always, but it often reduces control on loose or irregular material.
How can you tell the approach direction is wrong?
If the material shifts before full closure or needs re-grabbing, the direction is likely incorrect.
On site, control does not come from grip strength alone.
It comes from how the grab meets the material.
Get the approach direction right, and the load settles into the grab instead of fighting against it.
