Roll-on roll-off containers: vehicle, ground and load checks

A full roll-on roll-off container leaving a factory yard is one of the heavier single movements on most industrial sites. The hook-lift vehicle draws a loaded container onto its chassis, and problems with the standing area, overhead clearance or load can interrupt the lift.

Ground and overhead space

A hook-lift needs room in front and behind to pull a container on and to set the empty one down. It also needs firm, level ground. Containers left on soft ground, cracked concrete or over drain covers can sink, tilt or damage what is beneath. Where containers are swapped often, a dedicated hardstanding saves trouble.

Look up as well as down. The hook arm rises well above the cab during a lift, and overhead cables, pipe bridges, canopies and building edges have been struck by hook-lifts in yards that seemed spacious at ground level. A container position should be checked with the vehicle in mind, not just the footprint of the box.

Load weight and containment

Container capacity and legal vehicle weight are different limits. Dense waste such as metal offcuts, soil, rubble or wet sludge can bring a container to the vehicle’s plated weight long before it looks full. Overloading can expose a vehicle operator and driver to enforcement action. The site also needs to tell the collector what is in the container, especially when the material is dense. That gives the transport team a better basis for choosing a container and planning the lift.

Loose loads also have to stay on the vehicle. Open containers of light waste, cardboard, plastics or dusty material need suitable load restraint or covering so nothing escapes on the road. Waste that is overfilled above the sides cannot be contained properly and may be refused.

Questions to settle with the waste contractor

• Which waste streams go in which container, and whether any are hazardous.
• Where the vehicle will stand to swap containers, and at what times.
• Whether the container is open, lidded or enclosed.
• How the weight of each load is recorded.

Duty of care paperwork

The site producing the waste has duty of care obligations. It should check the carrier is authorised, describe the waste accurately on the transfer paperwork and establish where the load is going. Hazardous waste uses consignment documentation rather than an ordinary waste transfer note. Mixing waste streams creates a separate classification issue before the vehicle ever arrives.

A working arrangement

industrial waste collections for manufacturing, process and utility sites are covered by Industrial Waste Management, including recyclable materials, liquids and hazardous waste. For the person managing the yard, the useful habit is to treat each container position as a standing vehicle movement, with its own ground, clearance and traffic plan, rather than a place where a box happens to be left.
