PrefaceThis is the second edition of CSA Z151, Concrete pumps and placing booms, and supersedes the first edition published in 2009. The Standard provides requirements for the design, manufacture, installation, operation, inspection, testing, and maintenance of concrete pumps, placing booms, and delivery systems.
This Standard was prepared in response to an increased number of incidents, resulting from equipment failures and power line contacts, involving truck-mounted concrete pumps. It is intended to facilitate a consistent level of safety for those who work in and around concrete pumps.
Existing standards, regulations, and other documentation for concrete pumps were extensively reviewed in the preparation of this Standard.
Key changes in the second edition include:
- addition of roles and responsibilities;
- addition of qualification requirements for concrete pump operators;
- updates to Clause 4 (Design), Clause 5 (Inspection and testing), Clause 6 (Operation); and
- addition of Annex A: Concrete boom pump safe work procedures, outrigger support options, and surface load bearing evaluation.
Scope1.1
This Standard applies to the design, manufacture, installation, operation, responsibilities, inspection, testing, and maintenance of concrete pumps, placing booms, and delivery systems.
Note: See Figures 1 to 6 for illustrations of the equipment covered by this Standard.
1.2
This Standard does not apply to belt-conveying machines, mortar-spraying machines, and dry-mix shotcreting machines.
1.3
In CSA Standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.4
The values given in SI (metric) units are the standard. The values given in parentheses are for information only. Nominal pipe sizes are expressed in non-dimensional terms.
