Impact Bed

Product Overview

Impact beds are used in place of impact idlers/rollers and are installed under the belt at the loading points to absorb the impact from falling material.

QMH® impact beds are custom designed to suit your requirements. They are constructed from steel for a robust and long-lasting service life.

Designed with a modular pin-lock system for easy assembly and disassembly, our impact beds are fitted with highly absorbent impact bars to form a complete belt support system.

Available Options

Standard Impact Bed

This is our go to unit for regular bulk conveying jobs. It works well for medium sized feed material, moderate drop heights and normal throughput rates. Most general conveyor loading set ups can use this cost saving standard model.

Custom Impact Bed

Every job site comes with its own limitations. QBF Rubber Engineering designs and builds custom impact beds for non standard belt widths, unusual drop heights, tight installation space or highly abrasive material. Send us your conveyor specs and site notes, we will adjust frame structure, impact bar layout and mounting dimensions to match your actual equipment.

Hybrid Impact Bed

QMH® hybrid impact bed combines impact rollers and side support bars within one single assembly. You get roller aided belt movement plus firm edge hold from side bars.

This design delivers reliable control on belt edges. It maintains good sealing between skirting rubber and moving conveyor belt, cutting dust leaks and material spill over. It also minimises belt sag and belt shift caused by uneven material loading. Hybrid impact beds are ideal for sites where dust containment and stable belt tracking are top priorities.

Heavy Duty Impact Bed

This model is made for tough working conditions: oversized lumps, heavy bulk material and high drop heights.

It features a fully welded heavy gauge steel frame. Large diameter connection pins stand up to shear stress under repeated hard impacts. Matched with high absorption impact bars, the heavy duty unit takes violent shock from big size rock, ore and heavy bulk goods. It avoids frame distortion and extends service life in high shock loading areas.

Core Features & Real World Benefits

Applications

Install QMH® impact beds on all conveyor loading and transfer points. They are widely used across these industries:

• Mining & mineral processing
• Quarry and stone crushing plant
• Aggregate, sand & gravel handling
• Cement plant bulk conveying lines
• Recycling facilities
• Port bulk material terminals

Practical tip: Pick heavy duty version for large lump material or drop height over 1.5 m. Choose hybrid type if dust sealing and anti sag performance are your main concerns.

Impact Bed Dimensions

Technical Parameters

Notes

1. The distance between the two sides of the impact bed and the idlers can be set to 200mm.
2. All the above data can be adjusted accordingly as required by the general layout of the belt conveyor, and the troughing angle is adjustable.
3. The length of the impact bed can be manufactured according to actual design requirements, with standard lengths: 1000mm, 1200mm, 1400mm, 1500mm, 1600mm, 1800mm.
4. The CH value can be designed to match the central idler height of the troughing idler.

Reasons to Pick QMH® Impact Beds

Pin lock modular build saves labour cost on installation and maintenance work • Four series available: standard, custom, hybrid and heavy duty, covers most working conditions from general conveying to heavy lump material impact • UHMW PE, rubber and metal base are hot vulcanised together, great for shock resist and anti abrasion • Well designed surface layout improves dust sealing, cuts spillage and lowers belt damage risk • Replacement impact bars are stocked for quick on site maintenance

FAQ

Q1: Should I choose impact bed or impact idler?

A: Go for impact beds if you keep seeing belt tearing, bad spillage or heavy dust at loading zones. Traditional impact idlers have gaps between rollers. Fine and sharp material can squeeze belt into those gaps and create long rips. Impact beds offer full area belt support and fix such common issues. Impact idlers are still acceptable for light load applications with low material drop.

Q2: Can I only buy spare impact bars instead of full sets?

A: Yes. Impact bars are wearable consumable parts. We supply standalone replacement impact bars compatible with QMH® impact beds. There is no need to replace the whole steel frame.

Q3: Will custom impact beds cause longer lead time?

A: Custom solutions need drawing confirmation, so lead time will be longer than standard products. Provide us belt width, drop height, material type, lump size and space limits at an early stage, and we can speed up your project progress.

Q4: Does impact bed add belt friction and raise power consumption?

A: Our units adopt low friction UHMW PE surface. Friction increase stays minimal under normal operation. Keep impact bars at proper height, avoid over compressing the belt, to hold power draw at a reasonable level.

Q5: What routine work is needed for impact bed maintenance?

A: Carry out regular visual inspection. Check UHMW PE surface wear, rubber cracks, loose pins and deformed steel frames. Replace heavily worn impact bars in time. Thanks to quick detach U groove structure, bar replacement can be finished without taking apart the whole conveyor assembly.
