What safety controls should be carried out on demolition high reach equipment?
The maintenance procedures and periodic inspections are necessary elements in guaranteeing the efficiency and security of high reach demolition equipment.
Such procedures, as applied by national regulations for safety at work, also play an important role for this type of equipment where safety is not only guaranteed by the professionalism of the operator but also by the efficiency of active and passive protection systems which have been installed.
Manufacturers set inspections and scheduled maintenance activities according to the specific characteristics of each machine. These inspections and their frequency are described in the use and maintenance manuals, as issued by law. To ensure that the machine meets minimum efficiency levels whilst in operation, the operator or any suitably qualified person should carry out some simple visual checks before using it:
Type of control | Checklist | Schedule |
Visual inspection concerning the general state of the machine | General state of the machine; the presence of cracks or fissures in the arm, in the connecting pins; oil or liquid leakage from the engine. | Daily |
Visual inspection of plates and locking systems | Verify all the bolts tightening, presence of cracks or fissures, presence of elements with inaccurate coupling and locking plates. | Daily |
Hydraulic links check | Check hydraulic tube links, hydraulic cylinders, hydraulic connections and hoses for leaks | Daily |
Control of active safety systems (alarm beepers, video camera) | Verify functionality, incolmeter warning sensors if fitted, and boom position alarms, when carrying out scheduled manoeuvres. | Daily |
Control of the efficiency of glass surfaces and mirrors of the cabin. | Verify the integrity of the glass surfaces and mirrors ensuring proper cleaning to have the necessary visibility. | Daily |
Monitor signs and icons on the machine | Check the reliability and legibility of the icons and signs installed on the machine. | Daily |
Control of the efficiency and the functionality of the utensil | Verify the presence of cracks, oil leakage, the efficiency of the blades, points and teeth; effectively run tests of rotation before using the utensil. | Daily |
In case, during the visual inspection, elements of failure or malfunctioning are found, the use of the machine is prohibited and the Site Manager must be immediately advised. Any maintenance must be undertaken in line with the operating manual.
