SAFE WORK PRACTICE De-mounting, mounting and correct handling of Wheel Assemblies onto spoke Hub Axles. Issue: This SWP has been developed to advise recommended procedures for the correct mounting and de-mounting of multi-piece tyre and rim assemblies. SPECIAL INSTRUCTIONS: Only those persons who have been specifically trained are authorised to perform these duties. This procedure is to be used in conjunction with any operating manuals or training relevant to the task and by “Authorised Personnel Only” SEQUENCE OF JOB IDENTIFIED HAZARDS HAZARD CONTROLS MINIMUM PPE (what to do in the right order) (Applicable to each step) (Identify equipment, safety, quality, environment and performance requirements) FOR ALL OPERATIONS De-mounting Tyre and Rim Assemblies Jack the tyre off the ground Movement of plant, vehicle or machine Chock wheels of plant. Ensure jack and blocks are secure Gloves, Safety eye wear Safety boots Deflate the tyre pressure by removing the valve from the valve stem Worn, cracked, damaged or corroded parts may fail explosively from inflated air pressure Ensure tyre is completely deflated. Release the tension on the rim clamps before completely removing the wheel clamp nuts Wheel clamps can eject with force causing death or serious injury Only undo nuts leaving the full nut on the stud. Give each clamp a tap with a hammer to ensure each one is loose Demount the wheel from the hub Manual handling injuries It is mandatory that a forklift or similar is used to demount the tyre from the hub Inspect the rim clamps and rim and rim clamp nuts for signs of cracking and distortion Failure of clamps/ nuts on reassembly or in service. Replace worn, cracked, damaged or corroded parts immediately. Store the tyre safely Tyre rolling or falling over. Physical injury Ensure the tyre is safely chocked, propped or placed in a storage rack
Mounting Tyre and Rim Assemblies. Check that the spoke wheel and rim mounting surfaced are clean Failure of parts explosively on inflation or in service. Result can be injury or death Ensure that wheel and rim are free from damage, paint, dirt or rust. Gloves, Safety eye wear Safety boots Check the rim base, lock ring side ring and rim spacer. Failure of parts explosively on inflation or in service. Result can be injury or death Inspect all parts for cracks, wear, damage or corrosion; replace any part if in question. Do not attempt to rework, hammer, weld, braze or heat any rim base or component. Mount the tyre on the hub Manual handling injuries. Failure of tyre and/or rim It is mandatory that a forklift or similar is used to mount the tyre on the hub. Ensure the tyre correctly aligned with the hub before lifting the tyre. If a dual tyre arrangement, ensure rim spacer is inserted and the air filler stem of the inner tyre is watched carefully. Install all rim clamps and nuts Failure of components in service. Run the rim clamps down until the end of the stud is flush with the face of the nut. Revolve the wheel a half turn to seat the parts naturally. Tighten the rim clamps down until they are snug, using the method. Tighten nuts to recommended torque. Inflate the tyre Explosion of parts Result can be injury or death Use an approved restraining device. Ensure to use an extension hose with gauge and clip on air chuck. Inflate to recommended pressure. Stand clear of the assembly during inflation. Check rim nut torques regularly Failure of components in service. Loss of vehicle control Loss of wheel Check rim nut torque after first 50 kms of service. Attach sticker/label to steering wheel to inform driver of re-tension requirements Approved by Manager/Supervisor: Date: / / 2016
