SCAFFOLDING HOISTS Sample Clauses

SCAFFOLDING HOISTS. Each scaffolding hoist must be inspected and subjected to an operational test by a competent person before being sent to a job. Such a test must include lifting a test load of 1.25 times the rated working load of the hoist (even if the hoist has a load-limiting device) up a distance of not less than 3 m, lowering the load, and arresting and sustaining the load in any position without the hoist showing over-straining of any part. Any daily on site inspection by an operator must check that: • The directional switches function correctly. • Any emergency stop button operates correctly. • Any top limit switch operates. • The emergency crank handle is fitted, if there is provision for such an item. • Where the emergency crank handle has an electrical interlock, loosening of the handle will cut-off power and re-tightening of the handle will return power to the controls. The emergency handle must be left tightened. Weekly on-site inspections must be made and results must be recorded on an inspection register maintained at the job site, which must include: • Evidence of having passed an operational test, where the suspended scaffold is run up and down a sufficient distance to ensure that all operational controls on each attached scaffolding hoist function correctly and the mechanism does not produce unexpected noise or vibration. • Date of test. • Serial numbers of the scaffolding hoists inspected. • Name and signature of inspecting persons. Each scaffolding hoist on a job should be returned to a maintenance shop for a thorough inspection and maintenance program carried out by a competent person, at periods nominated by the manufacturer but not exceeding six months. Such six-monthly inspections should be recorded in a maintenance workshop or base office, which should include: • Test notations. • Dates of tests. • Dates of services. • List of parts replaced. • Test load and related working load of the hoist, in kilograms. • Statement that the hoist performed the test satisfactorily. • Name and signature of the servicing and testing persons.
