Save labour and hire costs
If you or your customer don’t have a forklift on site then the chances are you’ll normally have to borrow one from a friendly local company, or hire one in. Borrowing a forklift isn’t always easy and can come with strings attached, and hiring one in can mean also having to hire a certified operator. With a truck mounted forklift the machine is driven by the lorry driver, so there’s no wasted labour and it comes on the back of the delivering lorry. This removed entirely the delivery and collection costs of hiring a separate machine in and halves labour costs. Even if you or your customer has a forklift, having a self offload vehicle allows that machine to keep on working its usual job which can save an hour or two of labour. As we all know that hour or two can make a big difference on site.
Health and safety
For sites with no forklift often the only way of unloading is by hand. Manual lifting of even relatively light loads from the bed of a lorry can result in strain and injury providing you or your customer with problems with staff taking time off sick, or even HSE prosecution.
Time is money, and having a lorry on a site or in a yard can be a big inconvenience in some situations. Manual unloading of goods by hand is clearly slow, but even with a hiab palletised goods can take a long time to unload as every pallet has to have lifting chains attached and removed with the operator or a banksman going between the vehicle and the ground (see health and safety above!).
