Arms:
Mobile elements interconnected with pivots, operated by hydraulic cylinders. Usually made up of multiple units which allow the elevation and use of the attachment.
Attachment (working tool):
Assembly of components that can be mounted onto the base machine or equipment for specific use.
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.
Boom:
One of the elements which composes the front linkage.
Carrier / Base machine:
The machine where the attachment is fitted, allowing this way its 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
Control Measure:
A process or procedure – physical or otherwise – that is put into place prior to the commencement of a task to eliminate or mitigate against harm
Counterweight:
Element usually located in the back part of the base machine with the purpose of balancing the weight and the dynamic actions of the
Demolition excavator:
Demolition excavator designed and fitted with bespoke or specialist demolition attachments to make it suitable for demolition work.
It must have sufficient size for the work to comply and the activities to carry out, such as height enough to reach in a safe manner the structures to be demolished.
Demolition excavator with high reach arm:
Specific machines which constructed to carry out specialised demolitions of buildings and structures of high elevation and designed to operate high reach work
High reach work equipment is a multi-piece rigid, pin jointed or telescopic equipment with the primary function of operating specialised attachments for the demolition of structures at heights that cannot be reached by standard backhoe work equipment. Typically, the operating height of the attachment on a high reach demolition excavator is above 15 m, although this number may vary, as what truly defines a high reach excavator is its particular characteristics, rather than the height it reaches.
Distance to the building:
The measured distance at ground floor level between the face of the building and the front of the machine track. A minimum of a 2-1 ratio should be considered.
Exclusion Zone:
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.
Equipment:
The set of components mounted onto the base machine that allows an attachment to perform the primary design function of the machine.
Excavator:
A self-propelled machine on crawlers, wheels or legs, having an upper structure capable of a 360° swing with mounted equipment and which is primarily designed for excavating with a bucket, without movement of the undercarriage during the work cycle.
FOGS (Falling Object Guarding System):
Cabin resistant to shocks due to falling objects, directly connected to the structure of the base machine.
Fore boom:
One of the elements which composes the front linkage of high reach demolition machines.
Height of demolition:
The height of the demolition measured from ground level.
Height of the building:
The height of the building measured from ground level.
High reach equipment:
It is multi-piece rigid or telescopic equipment with the primary function of operating specialised attachments for the demolition of structures at heights that cannot be reached by standard backhoe equipment.
Inspection:
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.
Operating mass:
The mass of the base machine, with equipment and empty attachment in the most usual configuration as specified by the manufacturer, and with the operator (75 kg), full fuel tank and all fluid systems at the levels specified by the manufacturer and, when applicable, with sprinkler water tank(s) half-full place before the beginning of a job in order to eliminate or mitigate against harm occurring.
Operational height of the excavator:
With the machine fully extended to its maximum height measured from the centre of the tool mounting pin to ground level.
Quick coupler:
A device mounted on an excavator to allow the quick interchange of attachments.
Risk assessment:
A document or process to identify a significant hazard on site and the likelihood that such a hazard may cause harm.
Stick / Arm / “Dipper”:
One of the elements which composes the front linkage.
Track frame:
Track frame on the demolition machine composed of crawler tracks and side members.
Undercarriage:
Supporting framework located underneath the carrier; the structure to which the wheels, tracks, or the like are attached or fitted.
Uppercarriage (superstructure):
Element of the carrier which contains the engine, hydraulic system, cabin and/or counterweight.
