According to the standard EN 474-1:2007+A6:2020 (Earth-moving machinery – Safety – Part 1: General requirements), an attachment is defined as a “component or assembly of components, which can be mounted onto the base machine or equipment”.
Demolition and recycling attachments are those tools designed and manufactured specifically to be attached to the dipper arm or main boom of demolition and recycling machines, either directly or via a quick coupler.
Quick Coupler (Quick Hitch):
Quick couplers are used with construction equipment to allow the rapid change of buckets and hydraulic attachments on the machine. They remove the need to manually drive out and insert the mounting pins for attachments for each change. Quick couplers essentially improve the speed and productivity in demolition and recycling industry where many different attachments are used for different work and requires frequent changes.
It is the machine where the attachment is fitted, allowing this way its use. Demolition and recycling attachments always require a carrier to provide power and to move them into the working position.
Attachment and carrier must be compatible, and the carrier should be powerful enough to get maximum productivity out of the attachment, but not so powerful that it causes damage or premature wear to the attachment.
The swing or working area, of the machine, in which all workers shall be prohibited from entering in the event that an attachment or material held within the jaws may become detached and fall.
A document or process to identify a significant hazard on site and the likelihood that such a hazard may cause harm.
A process or procedure, physical or otherwise, put into place prior to the commencement of a task to eliminate or mitigate against harm occurring.
A process and procedure to be enacted prior to the operation of the attachment in which any defects or irregularities should be noted and dealt with.
