driveonloadoff

Drive-on load-off is a transport and handling method in which wheeled cargo is moved by driving onto and off of a platform, vessel, or trailer. It is commonly used in roll-on/roll-off operations and vehicle carriers, but can also apply to portable loading platforms and trailerized equipment. The method contrasts with lift-on/lift-off operations that rely on cranes and hoists.

Operationally, drive-on load-off requires accessible ramps, securement gear, and clear lanes for wheeled vehicles. Drivers or operators guide the cargo onto the loading area, secure it with wheel chocks and restraints, and depart after ensuring proper balance and clearance. For vessels or trailers, ramps must support the cargo weight and width, and loading plans coordinate sequence and spacing to maximize throughput and stability.

Applications include automobile and equipment shipping, ferry services, construction and heavy equipment transport, and on-site temporary storage where wheeled movement is needed. It is favored for its speed and reduced handling compared with lifted loading, and it minimizes the need for cranes or heavy lift equipment.

Limitations include ramp strength and length constraints, payload limits, weather exposure, and the requirement that cargo be wheeled or easily wheeled or towed. Non-wheeled goods require alternative handling methods. Safety considerations focus on securing, braking, and operator training.
