Weather Eye: Looking after Loading Bay Equipment

Loading bay equipment represents a major investment to any cargo-handling concern. True, much of it is made of particularly heavy metal but like any other mechanism, it can't look after itself. The upside is that, in many instances, loading bay equipment maintenance is relatively simple. The downside is the dreaded 'D word', downtime.

Loading bay equipment may be costly in the first instance but it can pay for itself. Downtime can be costly and the frustrating thing is that it can be avoided with a little intelligent attention. There is, however, a caveat to be borne in mind. Many loading bay managers budget for and use professional equipment servicing and maintenance teams, for a reason. There are certain tasks in servicing and maintaining this hardware which are best left to the pros, for the sake of safety as well as that of continued usability. Nevertheless, loading bay equipment can be monitored and simple maintenance and servicing tasks can be carried out.

So how do you monitor loading bay equipment? The answer to this is perfectly simple and concerns developing a good habit within the workplace. What habit? We can give this the acronym 'E.E.E.' and apply what it stands for. Examination, Evaluation and Execution is a trio of words that is easy enough to remember; let's see how they work.

Anyone employed in a fully equipped loading bay soon develops a sense of why each piece of equipment is present and what each does. The first part of the 'E.E.E.' principle stems from this. Appoint one person to 'do his/her rounds' say, once a week, checking over each part of the loading bay equipment in turn. Is it all working as it should? Could it be better? Is it broken? These questions are easily answered.

The process of examination needn't be limited to a weekly round. As loading bay personnel necessarily use items of equipment on a daily basis, any shortcomings could be reported as and when they develop. A marker board and pen in the loading bay could be used for personnel to log the fault(s).

The second step, evaluation, is important. Americans say "If it ain't broke, don't fix it"; in this context, "If you don't know how to fix it, don't try" would be more appropriate. Should the problem be a simple one, a matter of applying lubrication or tightening a fastening, personnel can go on to the next step. However, should a less amenable problem arise, it makes sense to seek professional help. This should be done, no matter how tempting a fast and easy fix might be. If a repair was to be carried out inexpertly, it could lead to a real, imminent or actual danger to personnel or equipment. Apart from the evident risks of damage or injury, it's more than likely that such a repair would render the relevant insurance cover null and void.

This leads us to the notion of execution and whether it can or cannot be done. Once again, it's a matter of applying intelligent forethought. For example, if some pivot or track squeals loudly in use, lubricating it is hardly rocket science. Similarly, a loose bolt, a blown bulb or the like can be sorted out quickly and easily. More complex repairs might not be so easily executed.

In the end analysis, the 'E.E.E.' principle has value in ensuring that most loading bay equipment failures can be discovered before they happen. Even if the necessary repair or refurbishment is a matter for experts, finding the trouble early can save money, and avoid the dreaded downtime.

Level Playing Field: Dock Leveller Facts and Figures

Loading bay personnel face problems every day but one everyday problem can be solved with the aid of an essential piece of equipment. The snag lies in any discrepancy between the height of a truck's load deck and that of the loading bay's platform. Should a mismatch exist, it has to be bridged and this is what a dock leveller does.

Sounds simple enough, doesn't it? In a way, it is but there are caveats of which every loading bay manager must be aware. Such as? Well, like any 'link' in the loading bay's chain of components, the dock leveller has to be capable of handling the heavy loads involved. When bearing these loads in mind, it isn't merely a matter of considering the avoirdupois weight of the goods concerned. This may be significant but a dock leveller also has to accommodate the weight of the means by which the goods are moved, be they trolleys, palette trucks or forklifts. In this context, the weight of the individuals handling the goods is insignificant but the dock leveller must also cater for the additional, near-horizontal loads applied by the moving and braking, especially of powered equipment. Load ratings of 6,000 or 9,000kg are popular but it's common for specially rated dock levellers to be offered in a variety of sizes.

The two main types of dock levellers share steel construction and feature proven aspects including an anti-slip deck and a corrosion-resistant finish. The difference exists in the lip that lies adjacent to the truck's load deck. This may be simply hinged but a telescopic lip version is also available. The dock leveller's height adjustment works equally well in either case but a telescopic lip also allows fine-tuning of the dock leveller to the relative positions of itself and the truck bed. Unsurprisingly, a European standard, EN 1938, applies to dock levellers; make sure the chosen unit complies.

Dock levellers may be mounted in a purpose-built pit and there are suspended frame versions for use with tail lifts. Moreover, dock levellers offer a mechanism that makes for ease of use. An electro-hydraulic operating system, powered by an electric motor that has a low-voltage control unit, makes applying the relative adjustments not only child's play but also the work of moments.

While they have to be visibly tough, dock levellers must also have hidden strengths. In a correctly designed unit, the support frame will transmit loads from the truck's deck without incurring fatigue and consequent loss of structural integrity. Limited torsional diagonal loadings should also be tolerated; dealing with a vehicle with a canted bed will impose them. Furthermore, while dock levellers may seem to be laughably simple items, a range of optional extras takes them into a higher realm of functionality. Such extras include practical additions like high impact absorbing buffers, brush seals for the sides and rear of the deck assembly and under-deck foam insulation. More, let's say, active options include automatic, synchronised parking, a vehicle restraint system with an interlock facility, an automatic docking light interface, and a door interlock mechanism.

As is undoubtedly clear, some forethought is needed when choosing dock levellers. Given this, those chosen should give the loading bay long-lived, reliable levellers that make light work of loading and unloading while maximising loading bay uptime.
