Approach buffers for loading ramps: Stop damage, choose correctly
A truck docks – and something bangs? Welcome to everyday life at the loading dock. This is exactly where decisions are made. Starting buffer (also: dock buffer / impact protection) determines whether you are only unloading briefly. or you'll have to repair it expensively later. This article provides you with clear selection guidance, practical assembly steps, and more. Most common mistakes – so your ramp doesn't become the "repair subscription" department. 🙂

Why loading ramp buffers save money
The starting energy doesn't end up in the wall, dock leveler or gate frame – but in the buffer. Sounds simple. And it is. And that's exactly why it works.
A bent dock area means: ramp closed. And "ramp closed" means: chaos in the process. A start-up buffer costs less than half a day of downtime.
The less unplanned damage, the less dangerous improvisation is needed. Crash protection is a matter of safety culture – not just rubber on the wall.
If you already know you need crash protection: Here you'll find all the suitable options: View starting buffer and for quick, complete solutions: Complete sets of starting buffers .
Typical damage without impact protection (checklist)
Without a starting buffer, your ramp takes on the role of a "shock absorber". And she can't do that. Here are the classics we see all the time:
- Cracks / spalling on the concrete front (especially at edges)
- Damage to the loading bridge (impact points, bent components)
- Gate frame/jamb warped → Gate is difficult to open or rubs
- The gate seal (shelter) tears or is "blown away" by a hairdryer.
- Screws loosen on adjacent components due to vibrations.
- Damage to the rear of the vehicle (expensive + discussions + loss of time)
If you already see "temporary" solutions at the ramp (wooden beams, metal brackets, homemade buffers), This is a clear sign: A clean solution is lacking.
Not the damage itself – but the repetition . Without crash protection, you can't even repair it. You subscribe to it.
What exactly does a starting buffer do?
A starting buffer is a robust component at the dock front. It absorbs energy during docking by compressing itself (depending on its design). or the force is distributed over several layers.
The truck should go against the buffer – not against the wall, dock leveler or gate.
Depending on the extension, the buffer ensures that sensitive components do not "get caught", how tough a driver is these days.
Not a "Please approach very carefully" – but a dock designed for reality.
Note: Starting buffers do not replace a complete safety strategy – they are one component. That's the central part of it. We'll cover the rest (traffic light, control system, sealing) further down.
The correct mounting position (height & distance)
The best quality is useless if the truck misses the buffer. Therefore, the rule is: position first, product afterwards.
The buffer must hit the area where the rear of the truck is actually touching. In mixed traffic (van + semi-trailer truck), combined solutions are often necessary. or additional vertical buffers are advisable.
Typically, there are two buffers to the left/right of the dock opening. Important: not too far out (miss the mark) and not too close in (collises with sealing/technology).
The loading bridge, dock seal, and dock frame have "protection zones". The buffer should be in front of them – not behind them.
Take a look at the ramp: Where are there signs of wear, nicks, or "black abrasion"? That's usually the actual contact area. That's exactly where your starting buffer needs to take effect.
Types of construction: Block, lamellae, PE/PU, spring buffer
There is no single "best" starting buffer. The design determines durability, damping, and maintenance requirements.
- Robust, simple, proven
- Ideal for many standard docks
- A good starting point if you simply want peace and quiet.
- Multiple layers → better energy absorption
- Often longer lifespan at high frequency
- Good choice for logistics with continuous operation
- Minimal abrasion, "clean" contact
- Can offer advantages in certain applications
- Important: the right combination of firmness and cushioning
- For special dock geometries or extreme impact
- More technology → more planning
- When things get explosive like in an action movie: look here
Material comparison (table)
Material is not about "taste". Material is about application. Here's a clear guideline:
| Material / Construction | Strengthen | Typical use cases | Pay special attention to |
|---|---|---|---|
| Solid rubber | Robust, attractively priced, good cushioning | Standard loading ramps, normal frequency | Projection + fastening (so that nothing "works") |
| Slats (rubber layers) | Excellent energy absorption, often longer lifespan | High call frequency, freight forwarders, central warehouse | Correct installation (flat surface + screw check) |
| PE/PU front | Less abrasion, in some cases higher wear resistance | Clean areas, special requirements | Hardness/elasticity: do not choose one that is too "hard". |
| Special/spring buffers | For extreme applications | Problem docks, special vehicles, unfavorable geometry | Clarify planning and installation situation beforehand |
Choosing the right projection: How to achieve the correct depth
The projection (i.e., how far the buffer "protrudes" from the dock front) determines, whether it actually protects – or is just hanging there decoratively.
The truck still touches the loading bridge, gate seal, or wall areas. Result: Damage despite "buffer present".
This can make the docking process annoying (greater distance), and in some docks even lead to incorrect positioning.
It matches the vehicle fleet, the dock technology and the gate sealing. If you're unsure: it's better to measure cleanly once than to reassemble three times.
- Which vehicles are docking? (Vans, 7.5t, articulated trucks, mixed traffic)
- Where are the actual traces of contact?
- Which components need to be protected? (Dock leveler, shelter, gate frame)
- How often does the docking occur per day?
- Only then: choose the projection and design.
How many approach buffers per gate/ramp?
The standard is often: 2 pieces per dock (left/right). But the standard isn't always correct. Depending on the gate width, vehicle mix and dock layout, 4 or additional vertical elements may be useful.
| situation | Recommendation | Why |
|---|---|---|
| Standard dock, clear layout, standard vehicles | 2 buffers (left/right) | Contact points are reliably intercepted |
| High frequency + frequent angled docking | 2 buffers + possibly additional protection points | More contact areas → less damage |
| Mixed traffic (van + semi-trailer truck) | Check combination / vertical solutions | Contact points are located at different heights. |
If you want it to fit perfectly right away: send us a photo + approximate measurements – then we'll tell you immediately, which combination makes sense.
Substrate & fixing: Concrete vs. steel
The best buffer is only as good as its mounting. If the screws are loose, everything will be loose – but not to your advantage.
- Drilling, cleaning the hole, selecting a suitable heavy-duty anchor
- Ensure a stable surface (no "crumbly" edges)
- Plan requirement: Buffer must not wobble
- Screw fastening to existing plates/beams
- observe corrosion protection
- Tighten screws regularly (to prevent vibrations)
- Check the substrate (cracks, voids, loose layers)
- Choose the appropriate screw length and quality
- Prepare a clean and flat mounting surface
If you keep having loose fastenings, it's often not a "screw problem", but a substrate/support problem (too close to the edge, substrate brittle, no clean flat surface).
Assembly step by step (with safety check)
Assembly isn't rocket science – but it's not exactly a quick job either. Here's the clear sequence:
- Block the loading ramp (really block it)
- Warning signs / barrier tape
- PPE: Gloves, safety glasses
- Determine the contact zone (abrasion marks help)
- Mark drill holes
- Check scales
- Select the appropriate drill bit
- Blow out/clean the borehole
- Do not set any "dust anchors".
- Insert anchors/screws
- Buffer plan tighten
- No tilting
There's movement, weight, and pressure at the ramp. If you're unsure, it's best to call in a professional. than having to "explain" an accident later. Safety always wins.
After installation: Check the seat and fine-tune.
Don't just check it off after installation. A thorough check will save you 80% of later complaints.
| Checkpoint | What you want to see | Unless… |
|---|---|---|
| The buffer fits flush. | No wobbling, no gaps | Check the contact surface, tighten, and reposition if necessary. |
| Screws tight | Defined tightening torque (according to manufacturer's specifications) | Incorrect anchor / incorrect drilling / subsoil problem |
| Contact zone fits | The truck hits the buffer, not the wall. | Adjust position (height/distance) |
Maintenance & Replacement: How to keep it safe
Start-up buffers require little maintenance – but are not maintenance-free. A quick routine check is usually sufficient.
- Cracks, breaks, severe deformation
- Loose fastenings
- Abrasion marks: is the truck still hitting the target correctly?
- At high frequency: check briefly more often.
- For infrequent use: visual inspection is usually sufficient.
- After an incident (severe impact): check immediately.
- When the buffer is visibly "gone" (material is missing)
- When screws no longer hold securely
- If damage to the dock occurs despite buffering
Common mistakes (and quick solutions)
Solution: Check the contact zone (traces), adjust the position or combine different approaches.
Solution: Protect components that are truly at risk (dock leveler/shelter). Select the overhang accordingly.
Solution: Check the substrate and the surface covering, and use suitable heavy-duty fixings.
Solution: Adapt the design/material to the frequency (lamellae instead of a block, if necessary).
Solution: Supplement the process: Traffic lights/flashing lights + clear docking rules.
Solution: Coordinate buffer position and door seal: Door seals/shelter .
Practical example 1: Freight forwarding company with high frequency
Heavy traffic means: many contact points, many small impacts, lots of abrasion. Solutions that distribute energy better and "stay cool" for longer often work here.
- Choose a robust design (louvers are often a good option)
- Consistent fastening: heavy anchors, flush mounting
- Supporting the process: Traffic lights/signals for clean docking
Tip: If you have multiple ramps, standardization is worthwhile – then you'll have replacements readily available.
Practical example 2: Cold storage / frozen food warehouse
Cold temperatures alter material behavior. Furthermore, sealing is usually particularly important in these conditions. because energy losses are expensive.
A combination of impact protection and sealing often brings the greatest effect here: Gap seals for ramps plus suitable shelter.
Damage is sometimes only visible later in cold weather – plan for regular visual inspections.
Practical example 3: Craft business / small farm
Lower frequency, but often a more diverse mix of vehicles. This is about finding a solution. which protects reliably without much fuss.
- Standard buffer + clean positioning
- Stable mounting so nothing wobbles
- If it's unclear: photo + measurement → short recommendation instead of guesswork
Combinations: dock sealing, gap sealing, traffic lights
Starting buffers are the foundation. Things really come together when you think of the ramp as a system: Protection + sealing + clear signals.
Reduces drafts, energy loss and "weather in the warehouse". Related: Shelters & gate seals .
For ramps, lifting platforms & transitions: View gap seals .
Clear process = fewer false starts: Traffic lights & flashing lights .
If you want to coordinate gates, traffic lights, dock levelers, etc. cleanly: Controls & Dock Control .
Product selection in the shop: Individual buffers vs. complete sets
In short: If you know what you're doing, individual buffers are sufficient. If you want to finish quickly and cleanly, Complete sets are often the stress-free solution.
- It's good when the fastening and substrate are clarified.
- Ideal for replacement/exchange
- View starting buffer
- Good for new ramps or modernization
- Clean overall structure, fewer bad purchases
- View complete sets
A photo and rough measurements are often enough to tell you the right direction. Then you only buy it once – not three times.
Bonus: If the gate is jerky – check the rollers and hinges.
Many loading ramps have a recurring problem: the gate is difficult to operate . And when things get tough, it's often closed "with force" – that backfires. Two components are almost always present: casters and hinges.
If the gate rattles, jams, or runs erratically: View ball-bearing rollers .
Play, delay, or rubbing sections? View roll holders & hinges .

News & Trends 2026: What's changing right now
Many companies are specifically upgrading their equipment: crash protection, sealing, signals – because downtime is more expensive than materials.
More focus on clear docking rules (traffic lights, release, conditions). This reduces damage – and arguments.
Markings, signals, robust protection points – because mixed teams and high throughput don't like mistakes.
FAQ
What is a starting buffer at the loading ramp?
A crash protection element that absorbs the impact energy during docking and protects buildings, docking equipment and gates.
How many approach buffers do I need per ramp?
Often there are two (left/right). In mixed traffic or difficult access situations, additional safety points may be useful.
Which discharge size is correct?
The projection must protect the components requiring protection at the front. Too small is useless, too large can disrupt the process.
Can I install the starting buffer myself?
Yes, provided the substrate, fastening, and safety measures are clear. If unsure: it's best to consult a specialist.
Why do starting buffers sometimes tear quickly?
Common reasons: incorrect design for the frequency, incorrect position, substrate/mounting is faulty.
How often should I check the buffers?
Depending on usage: check more frequently if frequency is high, otherwise perform regular visual inspections plus checks after hard impacts.
How much does a good crash barrier cost for the loading ramp?
This depends on the design, size, and installation situation. Important: Crash barriers almost always cost less than the first two instances of damage.
What are the benefits of combining it with a dock seal (shelter)?
You not only protect against impact, but also significantly reduce drafts, energy loss and "weather in the camp".
Should I get individual buffers or a complete set?
Individual buffers for replacement/targeted solutions, complete sets for clean new installations or modernizations without guesswork.
What do I do if the truck misses the buffer?
Then the position is incorrect: check for contact marks, correct height/distance, or use combined solutions.
Send us a photo of your ramp + rough dimensions (gate width, dock edge height, vehicle type). We'll tell you clearly which combination of starting buffers is suitable – no guesswork required.
