Practical Assessment - Rock Breaker

Information

Pre-shift Planning

Clarifies work location, task & work instruction
Ensures any required operating permits are completed / obtained
Identifies hazards in the work area: ~ inclement weather ~ dust ~ fog ~ poor lighting / reduced visibility ~ environmental, geological and survey data

Ensures the boarding steps, handrails and guard rails are in place, secure and free of grease / damage and secure. - Maintains 3 points of contact when: ~ boarding and dismounting excavator ~ cleaning window / mirrors / working lights
Ensures machine is isolated
Identifies excavator footprint
Starts at isolation point
Inspects / confirms attachments fitted are suitable for work: - Fit for purpose ( Chisel, moil, blunt ) - Damage, wear, structural cracks
Inspects all required components of undercarriage
Inspects all required components of attachment: - bent shaft - cracked tip - mushroomed ends - unusual wear patterns
Inspects all required components of lower superstructure
Inspects all required components of upper superstructure
Inspects all required components in / around cabin

Operator's can is reasonably clean, with no loose, unsecured or heavy articles in the cabin
Adjusts the mirrors for proper visibility
Adjusts the seat to body posture
Checks the foot pedals for reach and can be operated comfortably
Checks that the hand throttle / fuel dial control is at low idle
All instruments, including the emergency stop button, windscreen wipers, horn, air conditioner and instrument panel are undamaged and in working order
Windows and mirrors are clean and undamaged
Checks that the area around the excavator is clear before start up
Sounds the horn before staring up, in accordance with site requirements

Ensures all control levers / pedals are in neutral position
Checks the hydraulic lock lever is in the lock position
Checks the fuel control dial is in the low idle position
Turns the ignition key to the on position - checks electronic monitor before staring. - if engine dies not start, waits at least 2 minutes before starting
After the engine starts, wait for the engine oil pressure, battery charge and oil pressure lamps illuminate
Checks EMS / VIMS
Cycles all controls to check operation

Uses the following horn signals: - 1 blast before staring - 2 blasts before moving forward - 3 blasts before reversing
Waits 5-10 seconds after signalling before starting or moving the machine
Ensures the drive sprockets are at the rear of the machine
Increases the engine speed as required
Ensures work equipment is folded and raised 40-50cm off the ground
Moves the travel levers to move in required direction
Positions and sets up machine for safe, efficient digging ( tracks are in full contact with the ground, travel motors are at the rear of the digging area)

Operates excavator smoothly, with correct reach angle to allow optimum efficiency and minimise over load or strain on hammer
Operates all hydraulic functions smoothly & consistently
Ensures the hydraulic oil temperature is sufficient to start working
Handles oversize material safely & efficiently
Demonstrates steady & consistent operation of the machine aimed at minimising wear & damage
Ensures the area is free from personnel and other vehicles before commencing rock breaking activities
Position the tool at a 90 degree angle to the target. ( If the target moves material moves or the surface is demolished, did the operator correct the angle of the tool immediately )
Apply consistent downward force behind the breaker when it is operating & positions tool in the middle of the target surface.
If the rock shows no sign of breaking tHe operator repositions the rock and commences breaking from a different angle
Avoids idle percussion of the hammer, shank or tool
Stop the breaker before the tool broke through the rock
For every hour of operation, ensured the rock breaker attachment was greased

Ensures equipment is parked on firm, level ground away from pit walls
Reduce the engine RPM's and starts shut down process
Ensures bucket / attachment is lowered to the ground and neutralise equipment controls
Allows the engine to slow idle speed without load for 3-5 minutes before shutting down
Turn the key other off position
Applies hydraulic lock out lever
Ensures cabin is clean and the door is shut
Dismounts correctly using 3 points of contact
Isolates the battery power at the isolation switch
Inspects bucket /attachment for cracks / damage, excessive wear
Reports immediately if any parts are missing
Conducts walk around inspection, inspects for damage, excessive wear
Conducts site housekeeping requirements
