Rubble Chutes and Accessories

The hopper collects the rubble coming down from the upper floors through a chute and channels it into the skip or the container at ground level. It avoids carrying debris by hand down the stairs or lowering bags one at a time, reducing effort and risks. It is mainly used in renovations and demolitions, where the material to be disposed of is plentiful and continuous. Choose the model according to the height of the building and the type of rubble.

The choice depends on the material to be sent down and the working environment. The rubber chute suits abrasive and heavy materials, while the plastic one is lighter to move from one floor to another. Check the diameter and length according to the height of the building. Also make sure the joints and connections are compatible, because a section that does not fit can leak material.

The frame is the structure that holds the hopper and keeps it in position in front of the floor opening or window. The support is the fixing point that connects it to the facade, a scaffold or a column, depending on the model. Before buying, check that the attachment system is compatible with the structure you will mount it on. Installation must be carried out following the manufacturer's instructions and by trained personnel.

The chute must be fixed firmly with the supports provided, without resting it on non-load-bearing parts. Before starting, check that all the joints are tight and cordon off the area at the base to stop anyone passing under the discharge point. Italian Legislative Decree 81/2008 on workplace safety requires people to be protected from materials falling from above. While discharging, do not lean out of the opening and check that the safety chains or rings are intact.

The retarder reduces the speed at which debris travels down the chute, so the material reaches the ground in a more controlled way. It is recommended when the chute is long or when the rubble is heavy and loose. How it works depends on the model, so it should be chosen according to the chute length and the type of material. The retarder does not replace cordoning off the collection area, which remains necessary.

The anti-dust sleeve connected to the discharge mouth holds back the dust raised as the rubble falls. It makes sense in demolitions in occupied buildings or near windows, shops and walkways, where dust causes nuisance and hazards. Check it every time it is moved, because tears and loose connections reduce its effectiveness. When the job allows, combine it with damping down the area to cut the dust further.

The guide ring with chains and carabiners holds the chute in the correct position during discharge. The chains stop the pipe swinging or shifting when debris comes down. The carabiners must be clipped to secure points of the structure, never to parts not designed to bear loads. Before use, check that rings, chains and carabiners are not deformed, rusty or worn.
