CAN CSA Z151:2017 pdf download.Concrete pumps and placing booms
1.1 CAN CSA Z151 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 ilustrations 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.
4.1.2.1 The stability of truck-mounted concrete pumps with an integral placing boom shall be determined by calculating the static load imposed by the boom and its systems and mountings, plus the maximum allowable load imposed on the boom by the material in the delivery system (including the end hose),with the boom rotated to the least stable position. Calculation of the material load shall be based on the bulk density of standard concrete.
4.1.2.2 A representative unit of each model and chassis in each intended operating configuration shall be tested to verify the calculated stability.
Note: See Clause 5.4 for testing requirements.
4.1.3 Lifting attachments
Machines and machine parts designed to be lifted by cranes or other lifting devices shall be equipped with suitable attachment points. Any component weighing more than 227 kg with identified lifting attachment points shall have the component weight legibly and durably marked on the component.
4.1.20.2 A valve mechanism capable of crushing, tearing, or cutting shall be guarded by a cover grate on the opening of the charging hopper within the dimensions shown in Figure 9. Alternatively, the concrete pump and placing boom may be constructed in such a way that the pinch points are inaccessible.
4.1.20.3 Power-operated hopper cover grates or hopper covers shall have control devices that return to the neutral position when released. The control levers shall be far enough away from the crushing points to prevent contact with the moving parts.CAN CSA Z151 pdf download.
