A hoisting hatch is the closable opening in a facade or roof surface through which goods are hoisted inside with the help of a hoisting beam. On each floor of a warehouse or canal house there is often such a hatch, right below the hoisting beam in the gable top.
Structure
- Hatch opening — a door or window opening in the facade, usually stacked one above the other per floor
- Hatch doors — one or two leaves opening outwards or inwards
- Hinges and pintles — the ironmongery on which the leaves pivot
- Threshold — the lower edge over which the load slides inside
Function
The hoisting beam above the hatch and the slightly forward-leaning facade (raked) keep the load clear of the wall as it rises. At the level of the right hatch, the goods are pulled inside. Closed, the leaves protect the interior against weather and burglary.
Application
- Warehouses — for taking in merchandise on the storage floors
- Canal houses — for furniture and large goods that cannot go up the stairs
- Farmhouses — a hoisting or hay hatch in the gable for storing hay
- Repurposing — during conversion, hatches are often replaced by glazed panels while keeping the original shape
