01How telescopic loading works
The conveyor sits at the dock door on its base section. Nested belt sections telescope out into the vehicle to the depth the loading has reached, and retract as the load builds toward the doors. Parcels fed at the dock end ride the belt to the operator at the face, who places them directly into the stack. Unloading reverses the flow: parcels are placed on the belt inside the vehicle and travel out to the dock.
The gains are ergonomic before they are anything else. The walking-and-carrying distance per parcel collapses to the last metre; the lifting happens at waist height at a controlled pace instead of at whatever height a hand-stack reaches. Vehicle turnaround improves as a consequence — the crew at the face is never waiting for parcels, and parcels are never waiting for a carrier to walk back.
02The Goodscan telescopic conveyor
The telescopic unit in the Goodscan range is a mobile telescopic belt conveyor — a movable extending conveyor for truck and container loading and unloading in parcel and warehouse docks. Mobility matters in multi-door docks: one unit serves the doors in rotation, positioning at the active bay rather than being fixed to a single door, and moves aside when the dock needs the space for pallet work.
In a measured line, the telescopic conveyor is the last section: parcels arrive sorted by route from the sortation system, travel the take-away conveyors, and the telescopic section delivers them into the vehicle in the order they were sorted. The blog article on telescopic loading covers the dock patterns — swing trailers, multiple doors, mixed parcel and pallet docks — in more detail.
03Specifying reach and duty
The specification inputs are vehicle types (van, rigid truck, trailer, container), the dock arrangement (door count, dock levellers, yard slope), and the parcel stream the belt must keep up with. Extension depth is chosen against the longest vehicle; belt duty against the heaviest regular parcel. As a complete-machine supply, the telescopic conveyor is delivered as a finished unit — base, sections, drive and controls — not as an extension kit for an existing conveyor.
