Understanding Impact Beds

What is an Impact Bed?


impact bed dyna teamAn impact bed is a piece of equipment that is utilised on conveyor systems to assist the conveyor belt and structure to absorb the impact from falling material.

Usually located at the base of the chute, impact beds are designed with shock absorbent bars and a strong support frame.



Does My Conveyor Need an Impact Bed?


impact bedImpact beds should be considered when designing your conveyor system.

If the crushing process is unable to minimise oversized material from entering the chute, the impact zone will be open to extreme wear and tear.

Wear and tear may also occur due to large fall heights from the conveyor above.

The usual impact rollers and frames may be worn quickly or potentially break under the constant and heavy impacts.

In this case, impact beds should be considered. Impact beds have a higher impact rating and longer service life when compared to impact rollers.

Impact beds are a cost-effective way to minimise replacement impact idler rollers and frames.

If you’re currently working on or maintaining a conveyor system that is wearing through impact idlers quickly, routinely or just outright breaking, you may want to consider an impact bed.

Impact beds can be designed to fit almost any position.

Beneficial Features


Easy to Use Modular Pin-Lock System


The DYNA Engineering DYNA-TRAC® impact bed incorporates a modular pin-lock system engineered for the easy replacement of worn impact bars.

We found that the system worked so well that we deployed the pin-lock system across the whole impact bed.

One of the added benefits of the pin-lock system is the pins can be removed without any tools. Additionally, the bars can be replaced without removing the bed from the conveyor.

It is as simple as unclipping and removing the pins.

Adjustable Sides

The ability to lower the sides of the impact bed also assists with installation and removal.

The sides can be lowered to a horizontal level, allowing the impact bed to slide out from under the belt.



Other Options


Impact rollers can also be used in place of impact beds.

However, impact rollers have greater limitations in impact rating and service life when compared to impact beds.

Impact idler frames cannot be produced to absorb the same amount of energy as impact beds.

In high impact zones, impact beds will usually last much longer.
