Understanding a Chute: Before explaining how to assemble a chute, let’s first take a closer look at the chute itself. What does this entail?

A complete waste chute includes the following components:

• Chutes in the shape of a blunt cone made of plastic or galvanized steel, connected with chains, hooks, and eyes.

• A support structure (chute frame) for mounting a hand winch and to hang the chute. The frame must be secured to a window or scaffold.

• Window fixtures that clamp around the parapet and hold the frame and chute together.

• A hand winch with a support frame, used exclusively for mounting and dismounting chutes (lifting the chutes lying on the ground).

Important Note: Only original Müba construction parts are allowed for use with the chutes.

General Setup of the Chute:

• The maximum height for a plastic chute is up to 40 meters. If the chute is made of galvanized steel, the maximum length is 30 meters. When attaching the chute to masonry, the height or length can be up to 25 meters.

• The chute must be raised vertically and suspended in a vertical position for operation. Chutes with an intermediate fill piece must be mounted completely vertically. The construction elements of the waste chutes are sized for:

  • Maximum tilt during installation and disassembly.

  • Maximum operational tolerance of 10:1 (10 meters vertically, 1 meter horizontally).

The stability approval takes the following into account:

• The total weight of the entire structure.

• 2 meters of debris fill to account for blockages.

• Wind load according to DIN 1055 part 4.

• Horizontal forces from tilt and movement freedom of 10:1 (10 meters vertical, 1 meter horizontal).

Attaching a Chute to a Window Opening:

• The window attachments consist of two load-bearing elements with a distance of 740mm.

Components:

• Support column

• Telescope arm

• Alignment for bolts

• Load distribution (inside and outside)

• Support surface for the chute frame

• Coupling for the chute frame

The force distribution to the walls must be demonstrated by the user for each individual case.

Mounting Instructions for Masonry Structures:

• The maximum build height for chutes on masonry is 25 meters.

• The extraction length of the inner support column and alignment for the bolts in the telescope arm depend on the thickness of the wall.

• The load forces of the supports on the inside and outside of the masonry must be transferred to the rising walls, which must be at least 36 cm thick.

For this, inside and outside load transfer elements (e.g., horizontal braces) with sufficient dimensions must be used and secured against shifting or falling.

Mounting Instructions for Concrete Structures:

• The maximum build height for chutes on concrete and sufficiently reinforced wall parts is 30 meters for steel chutes and 40 meters for plastic chutes.

Window fixture installation is similar to masonry structures, using transfer elements for load distribution.

Attaching a Chute to a Scaffold:

• The chute frame is mounted to cross beams R, symmetrically positioned relative to the scaffold.

• The supports in the connection area must be anchored to the building. If existing scaffold anchors are used, the forces from the chute must also be taken into account.

Guidelines for Using the Chute:

• Lifting and lowering the chute is only allowed up to wind force 6.

• Operational fixtures using couplings must be applied immediately after final installation and may only be removed right before disassembly.

• The winch should not be left hanging with the chute in operation. The winch is solely for lifting and lowering the chute during installation and disassembly.

• At least two turns of the cable must remain on the winch drum when lowering the chute.

• The chute must always be raised and lowered vertically.

• In exceptional cases, a tilt of up to 10:1 is allowed (1 meter horizontally, 10 meters vertically) as long as the fixtures are strong enough.

• No parts larger than the smallest chute diameter (400mm) may be dropped into the chute.

• If blockages occur, the debris flow must immediately stop. The blockage must be cleared before resuming the flow.

• After a blockage, all load-bearing components, especially chains, carabiners, shackles, upper supports, and window and scaffold fixtures, should be inspected for damage and permanent deformation. Any damaged parts must be replaced.
