Impact bar / impact cradle / impact bed for belt conveyor
Used in the conveyor loading points or transfer points to replace
traditional cushion rollers.
It’s designed to absorb impact loading and help eliminate spillage
and scattering of the products.
This results in less wear and tear on your conveyor system,
dramatically improves the efficiency
and reduces the maintenance cost.
The impact bar is composed of three different Layers. The top layer
is made of virgin UHMWPE
sheet for movement of the conveyor belt. The middle layer is made
of rubber to cushion the impact
load.While the lower layer is for fastening impact pads on to the main
support frame, which is
usually made of aluminium. The impact bar is used in the loading
area of the belt conveyor to
replace the traditional cushion rollers. It's designed to absorb
impact loading which will dramaically
reduce shock and stress loading on the structure.
Material: * Virgin UHMWPE sheet surface
* Shock absorbing rubber
* Extruded aluminium
1. Avoids the damage to the belt through the contact between the
bar and surface of belt.
2. The conveyor belt is stressed evenly in the loading area, which
will reduce the daily maintenance
cost. It effectively eliminates the spillage or scattering of the
material caused by inequality of the
stress on the belt.
3. The UHMW polyethylene surface has outstanding sliding
properties, to reduce the frictional
resistance to the minimum.
4. Ultra elastic rubber absorbs the impact in the maximum.
5. Each part of the impact bar is closely jointed by hot
6.“T-track” fastening device has different tightening points along
the bar and make the joining
strongand reliable, easy to install and remove.
