ISO 16417-2020 pdf free download – Earth-moving machinery — Hydraulic breakers — Terminology and commercial specifications.
This document establishes the terminology and content of commercial specifications for hydraulicbreakers which are mounted as an attachment on a carrier, typically earth-moving machinery such asan excavator, backhoe loader, skid steer loader, and compact loader as defined in ISo 6165; or mountedon a rig, pedestal boom system, demolition robot, etc., at the end of an arm.
Hydraulic breakers are typically used to demolish or break rock, concrete, brickwork, asphalt, etc.This document does not cover breakers powered by pneumatic, thermomechanical, or electromagneticenergy. This document does not cover portable or hand-held breakers either.

3.1
carrier
mobile or stationary machinery that provides power and a range of motion for the mounted item
Note 1 to entry: Mobile machinery is typically an excavator, backhoe loader, skid steer loader,or compact loader.Stationary machinery is typically a pedestal boom system, demolition robot, etc.
3.2
attachment
assembly of components that can be mounted onto the carrier (3.1) for specific use
[SOURCE: IS0 6746-2:2003,3.5, modified—The term “base machine and equipment” has been replacedwith “carrier”.]
3.3
hydraulic breaker
percussive hydraulic attachment(3.2)used for breaking up concrete, rock, brickwork, asphalt, etc.
3.3.1 Accumulator
3.3.1.1
hydraulic accumulator
pressure storage reservoir that enables a hydraulic system to cope with extremes of demand and tosmooth out pulsations
3.3.1.2
piston accumulator
energy storage chamber charged with nitrogen into which the upper end of the piston (3.3.8)reciprocally projects and which imparts stored energy onto the upper surface area of the piston toassist with piston acceleration
3.3.2
back head
device that closes the upper end of the cylinder and has a space into which the upper end of the piston(3.3.8) reciprocally projects
3.3.3
bracketside plate
device that supports the power cell (3.3.7) which includes mounting holes to either bolt on to the carrier(3.1) mounting adapter(3.3.11) or to connect directly to the mounting flange holes on the carrier
3.3.4
tool
device that transmits the impact energy of the reciprocating piston(3.3.8) to the material to be broken3.3.5
front head
device that attaches to the lower end of the cylinder to guide and support the tool(3.3.4)3.3.6
housing
device that encloses the power cell (3.3.7) on all sides and has mounting holes or is connected to thecarrier (3.1) with a mounting adapter (3.3.11)
Note 1 to entry: ‘Types of housings can be side-mount open, top-mount open, side-mount closed, and top-mount closed.
Note 2 to entry: The reference to open or closed refers to whether the power cell is exposed or not, respectively.3.3.7
power cell
assembly generating impact energy, having piston (3.3.8), piston control valve (3.3.10), front head(3.3.5)and back head (3.3.2)
3.3.8
piston
device that transfers the energy of pressurized fluid and optionally nitrogen by moving reciprocally toimpact the tool (3.3.4) generating an impact force
3.3.9
through bolttie rod
device that ties the parts of the power cell (3.3.7) together
3.3.10
piston control valve
device that controls the reciprocating motion of the piston (3.3.8)
3.3.11
mounting adapter
device that connects the hydraulic breaker [3.3) to the carrier(3.1) for adapter-type hydraulic breakers.ISO 16417 pdf download.
