General
Plastic rubble chute for the safe disposal of construction debris and roofing materials from one or more floors. Thanks to the adjustable chain system, the chute can be placed at steep angles, allowing access to any location. The length of a single chute is approximately 100 cm.

What is a rubble chute?
Before explaining how to assemble a rubble chute, let's first take a look at the chute itself. What does it consist of? A complete debris chute typically includes the following components:

• Chutes in the form of a truncated cone made of plastic or galvanized steel, with connections using chains, hooks, and eyes

• Support frame (support stand) for attaching a hand winch and hanging the chutes

• Window attachments that clamp around the parapet and hold the support stand with the chute

• Hand winch with a support frame, specifically designed for assembling and disassembling the chutes (for lifting chutes lying on the ground)

Note: Only original Müba construction parts may be used for the chute system!

General setup of the rubble chute
The maximum height for a plastic chute – like ours – can be up to 40 meters. If the chute is made of galvanized steel, the maximum length is 30 meters. When attaching the chute to masonry structures, the maximum height or length is 25 meters.

• The chute must be pulled vertically and hung in an operational vertical position. Chutes with an intermediate filling piece must also be installed vertically.

• The components of the debris chutes are designed for maximum slant during installation and dismantling, with an operational tolerance of 10:1 (10 meters vertically, 1 meter horizontally).

Stability approval has considered the following:

• The weight of the entire structure

• 2 meters of debris to account for blockages

• Wind load according to DIN 1055 Part 4

• Horizontal forces from slant and freedom of movement (10:1)

Attaching a rubble chute to a window opening
Window attachments consist of two load-bearing elements with a distance of 740 mm.

• Support column

• Telescopic arm

• Alignment for bolts

• Load distribution (internal)

• Load distribution (external)

• Support surface for the support stand

• Coupling for the support stand

The force distribution to the walls must be demonstrated by the user in each individual case!

Assembly instructions for masonry structures:

The maximum build height of the chutes for masonry is 25 meters.

• The extension length of the inner support column (1) and the alignment for bolts (3) in the telescopic arm (2) depend on the thickness of the wall.

• The bearing forces on the inside and outside of the masonry (parapet) must be transferred to the rising, at least 36 cm thick walls on either side of the parapet.

Assembly instructions for concrete structures:
The maximum build height for concrete and sufficiently reinforced wall sections is 30 meters for steel chutes and 40 meters for plastic chutes.

• The assembly of window attachments consisting of two load-bearing elements is done as with masonry structures, using transfer elements for load distribution.

Attaching a rubble chute to scaffolding
The support stand is attached to cross beams R, which must be symmetrically positioned relative to the scaffolding's height.

• The brackets in the connection area (A, B, C) must be anchored to the building at the position where the support stand is attached.

Chute attachment to a standard scaffolding
When attaching the chute to standard scaffolding, it must be fixed parallel to the pair of scaffolding posts II. Scaffolding braces R with a tube diameter of 48.3 mm are required. These must not be inserted but should be attached using standard scaffolding couplings with approval B.

Chutes with intermediate anchoring
If your chute is shorter than 10 meters, you can hang it without intermediate anchoring. However, if your chute is longer than 10 meters, intermediate anchoring is required at a maximum distance of 8 meters.

Guidelines for using your rubble chute:

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

• Operational attachments must be applied immediately after the chute is installed and can only be removed just before disassembly.

• The chute must not hang from the winch when in operation. The winch is only for lifting and lowering the chute during assembly and disassembly.

• When lowering the chute, at least two turns of the cable should remain on the winch drum.

• The chute must be lowered and raised vertically at all times.

• A slant of 10:1 is allowed in exceptional cases if the attachments are strong enough (1 meter horizontally, 10 meters vertically).

• No items longer than the smallest diameter (400 mm) should be thrown into the chute.

• In case of blockages, debris feed must stop immediately. Blockages must be removed before resuming debris feed.

• After blockages, all load-bearing parts, especially chains, carabiners, links, upper support structures, and window and scaffolding attachments, must be inspected for damage or permanent deformation. Damaged parts must be replaced!
