Proof Load Testing of Lifting Equipment

Yield strength is a material property describing the highest internal stress in a material that an item could achieve without permanently deforming.

Ultimate strength describes the internal stresses at a load that would cause failure.

Almost all codes require an engineer to use the yield strength for design except in cases like fall protection. In this scenario, it is common to see ultimate strength used in conjunction with a high loading scenario and the requirement to re-inspect after it's been loaded. It is important to keep in mind that many high tensile materials such as quenched, tempered or high carbon steels have a narrow band between yield, ultimate and transition causing permanent bending to breaking very quickly.

Heavy Lifting Equipment

Even the strongest of workers will end up admitting defeat some time. And for the sake of their health, they should be encouraged to. It's easier to use lifting devices and lifting equipment anyway. After all, these strong helpers can transport loads and put them down in the right spot more safely, and thereby structure work processes in the company, from the warehouse to the workshop, much more efficiently.

Lifting devices and lifting equipment: are there any important differences to note when making a choice?

Yes, there are. Adding the term floor conveyors might help make the difference more obvious. These include all stacking and lifting devices that are primarily design for transporting loads. Pallet trucks or fork lift trucks are the best examples.

Classic lifting devices, in contrast, such as cranes, are useful, stationary products that use a specific action radius to raise and position heavy loads. They are particularly suitable for use when you need to move heavy machinery during operations, or you wish to use certain tools.

The question is therefore which functions your device should provide: do you need it for transporting goods or for lifting goods? This, in turn, will result in additional factors when choosing pallet trucks, lifting tables and similar products.

Which lifting equipment and lifting devices are essential for my business?

This will, of course, depend on the volume of loads needing to be transported or moved around in your company, and in which form. The daily work we have done with our customers has demonstrated that there are two devices that are particularly versatile:

Pallet trucks or fork lift trucks are needed in practically every industry as soon as goods arrive on pallets or need to be packed on them for shipment.

Mini lifters also provide extremely versatile functions, and the unlimited choice of accessories and custom-made models available make them real problem solvers, in workshops in particular.

Which factors is it important to note when choosing lifting equipment and lifting devices?

You'll only find devices at Second Lifting Equipment (Pty) Ltd which you are allowed to operate without requiring a corresponding driver's licence. The occupational health and safety regulations do, however, always apply.

Factors to note when choosing a device are, first of all:

The weight and dimensions of the goods
The required lifting range (vertical)
The fork length and distance across forks of the device for pallet trucks
Whatever the transport equipment, such as stackers, you are considering, choosing the right rollers is also decisive. The type of floor, along with weighing up whether smooth running or rolling resistance is more important, may end up making a decisive different to operations. You can find more information about this in the purchasing guide to wheels and castors.

Furthermore, you should always double check whether the device you are interested in really does suit the load you calculated. Or, put concisely, due to the load centre and for reasons of stability, you will usually need a device that features a higher maximum load bearing capacity than your well-informed guess might suggest. A device with a higher max load will also extend the range of jobs you can use your load bearer for.
