In any logistics operation, loading bays are essential to keeping loading and unloading under control. They play a decisive role, and it falls to them to keep deliveries running on time. If you are wondering what a loading bay really does and want to know more, follow our complete guide.
Before going into detail, it is worth being clear about what loading bays are, what part they play in the supply chain and which types exist.
A loading bay, also known as a loading or unloading dock, is a platform of critical importance in preparing deliveries. On one side sit the warehouses where goods are stored; on the other, the delivery lorries. The bay is, in effect, the link between the two.
Loading bays may be fitted with a mobile loading ramp, or they may take the form of fixed platforms. They house lifting cranes, mechanical ramps, forklift trucks and self-tipping skips. All of this makes it possible to load goods into lorries so they can set off on their rounds. The bay needs doors so that staff have free access, and it has to be sheltered from the weather, rain and wind included, so that goods are not damaged.
Logistics operations answer different needs, which is why several types of bay exist. First comes the loading bay, one of the most important. Depending on the size and configuration of your storage warehouse or shed, it may sit at the front or at the rear. Its purpose is to make loading goods into lorries easier.
The unloading bay, for its part, is where the contents of delivery lorries are taken off. It may be built alongside the loading bay and serve both functions, or it may be entirely separate: loading at the front of the warehouse and unloading at the rear, for example.
Finally there is the sorting bay. It is not always necessary, but it can be extremely useful if you have a wide range of goods going out to different destinations, since this is the platform on which every parcel is sorted.
Now that you know exactly what each type of bay is for, let us turn to their design, along with dimensions, spacing and layout. None of this should be overlooked.
Several standards and regulations govern loading bays. Accidents on these platforms can be frequent, which is why you are required, first of all, to draw up what is known as a safety protocol: a document setting out every risk associated with your operation.
You then have a duty to carry out checks before every logistics operation, in other words before each lorry is loaded or unloaded. You must satisfy yourself that the delivery vehicles have no mechanical faults and are completely immobilised.
Beyond the safety standards described above, regulations also govern the height of a loading bay. As a rule, that height should fall between 1.1 and 1.2 metres. In practice, the ideal height is dictated by the dimensions of the delivery lorries: match the two and loading and unloading become far easier. The bay should therefore be neither too high nor too low.
Depending on the type of lorry, the load bed may call for a bay height that differs from the norm. Here are a few examples to give you a clearer picture:
- For a van, between 0.45 and 0.65 metres.
- For a low-loader trailer, 0.65 metres.
- For a rigid lorry, between 0.85 and 1.05 metres.
- For an articulated lorry, between 1.1 and 1.2 metres.
- For a refrigerated lorry, between 1.2 and 1.3 metres.
- For a container trailer, between 1.3 and 1.5 metres.
As you can see, the height of your loading bay really does have to suit the types of lorry using it.
Several pieces of equipment have to be installed on a loading bay. They keep everyone safe and make every logistics operation easier. Even where they fall outside current regulations, they are essential to protecting your goods, and they need to combine sturdiness, efficiency and safety. Here are the main items we recommend.
The dock leveller, or bridge plate, closes the gap between the bay and the lorry. It is vital in preventing falls and accidents. Hydraulic levellers are the better choice, being far sturdier. Lorries are not all the same size, so when they pull up at the bay the gap can vary considerably. Leaving that gap open makes loading and unloading your goods more complicated, so a dock leveller is not something to go without.
A range of safety systems has to be installed on your bay to keep everyone safe. Signage is essential: floor markings, signs, safety barriers, traffic lights and so on. It is also possible, and indeed advisable, to fit dock bumpers, which absorb the impact as lorries pull into position. Without them, the risk of damage is much higher. As for the lorries themselves, we recommend investing in wheel chocks or an automatic restraint system, so that there is no chance of a vehicle moving mid-load.
To improve safety on your bay further and make daily work easier, you can turn to additional accessories and equipment. Most delivery lorries have a built-in ramp, but some vehicles do not, so tail lifts are worth installing.
To make loading and unloading more ergonomic and more straightforward, you also have the option of automated systems, digital tools and scheduling software. None of this is compulsory, but where large volumes of goods are involved it has become essential to find ways of keeping every operation flowing.
Managing what happens at the loading bay as well as possible matters a great deal, because the whole supply chain depends on it. If loading and unloading fall behind at the bay, every delivery is affected. You therefore need management methods that save you time, and that means scheduling delivery operations and maintaining the bays.
Scheduling your operations brings real benefits to your business. It means, among other things, setting appointment slots for loading and unloading your goods, so that too many lorries never converge on the same place at once. Without booked slots, delays build up quickly: if every vehicle arrives at the bay at the same time, the first have to leave before the next can collect their loads.
Delivering goods late has a negative effect on customer satisfaction, and not only that, since your staff bear the consequences too. Drivers lose a great deal of time before setting off, and bay operators come under pressure because they have to load and unload quickly to make up the lost time.
Finally, scheduling delivery operations benefits you financially. Fewer late deliveries mean substantially lower costs. You are not left with idle staff, and you do not have to pay your employees overtime. You can see why scheduling every operation matters.
As this guide has explained throughout, the loading bay can be a relatively dangerous area. Between heavy lifting, forklift trucks and other handling vehicles passing through, and delivery lorries arriving and leaving, the hazards are ever-present. On the bay, staff are in constant close contact with the vehicles and machinery used to move goods.
Maintaining all your infrastructure regularly is not a mere detail. That maintenance has to be regular if everyone working on the bay is to be properly protected. It certainly represents a cost, but one to be set against the number of falls, injuries and accidents that can occur.
The best approach is to schedule maintenance and servicing for the bays and the equipment so that it happens at regular intervals. Checking your equipment and machinery every day is not the same thing as servicing and maintenance: for that you need a genuine professional. The choice of contractor is yours, but make sure they are competent and available should a problem arise. Obtaining quotes will help you find the professional who best matches what you expect.
Train your staff in safety rules and in the correct use of handling equipment. First, every person working on your loading bay must be issued with PPE (personal protective equipment). Then you should invest in individual or group training sessions, run over the long term and on an ongoing basis.
Now that you know more about loading bays, all that remains is to put the advice set out in this guide into practice. If you have any questions, our teams are on hand to give you the answers you need.
