Fold-over chute safety device

A spacing device for use between first and second chute sections of a concrete mixing truck, wherein the first chute section comprises an annular flange adjacent to a second end of the first chute section, and the second chute section comprises an arcuate edge configured to contact the annular flange of the first chute section, the second chute section being pivotally connected to the first chute section, the spacing device comprising:

• a mounting flange for mounting to the first chute section adjacent to the second end and proximate to the pivotal connection of the first and second chute sections;
• a blocking member connected to the mounting flange, the blocking member comprising a contact surface spaced from the mounting flange, the contact surface being configured to contact a portion of the arcuate edge when the mounting flange is mounted to the first chute section, to maintain the first and second chute sections in a spaced relationship.

A blocking device for use with a concrete chute safety system on a concrete mixing truck wherein the concrete chute includes a first chute section having a first end connected to the truck, the first chute section having an annular flange adjacent to a second end of the first chute section and having a mounting flange adjacent to the annular flange, the concrete chute further including a second chute section having an arcuate edge configured to contact the annular flange of the first chute section, the second chute section being pivotally attached to the first chute section adjacent to the arcuate edge and the second end of the first chute section, the blocking device comprising:

• a blocking member, the blocking member comprising a first surface configured for connection to the mounting flange, and a second surface, spaced from the first surface, the second surface configured to contact the arcuate edge of the second chute section when the blocking member is mounted to the mounting flange.
