Prepare for and complete the Goldreef CV-07 belt splice

What is going on

Conveyor CV-07 at Goldreef Mining Services, a 1,200 millimetre four ply fabric belt, needs a hot vulcanised step splice on Tuesday under job card JC-26-3320. The crew leader wants you to prepare the job: the splice and step lengths from the splice table, the kit, cement and press, the Job Safety Analysis and the customer's isolation and permit arrangements. One cement lot is quarantined and must not be used. Two weeks ago at the same site the customer's isolation was found on the wrong drive and the crew leader caught it at the isolation test. A warranty repair on another splice traced to an edge that was not fully cured is also fresh in everyone's mind.

Your brief

Prepare the CV-07 splice job to the Hot Vulcanised Fabric Ply Belt Splice Procedure, including the splice geometry, kit and chemical checks, the Job Safety Analysis and the customer isolation arrangements, then carry out and record the splice on site with the crew leader, verifying isolation before applying personal locks and curing to the compound data sheet.

Work through it

You do not need to do it all. Doing a few of these will show you what the work is like. Your ticks and notes stay on this device.

• Read the Hot Vulcanised Fabric Ply Belt Splice Procedure and the site work section of the Work Health and Safety Policy and list the conditions that must be met before any work starts on the belt.
• Calculate the splice length, bias and step lengths for a 1,200 millimetre four ply belt from the splice table supplied and prepare the marking-out plan.
• Prepare the kit list including press, plates, edge irons, tie gum, cover rubber and cement, check the cement lot in Raw Materials and Compounds Stock, confirm the quarantined lot is excluded and record the lots on the job card.
• Complete the Job Safety Analysis Form for the job, covering travel, customer isolation, belt clamping, knives, solvents and ventilation, the hot press and cool-down, and manual handling of the press.
• Describe how you obtain and verify the customer's isolation and permit, including the drive test and the belt clamps, before applying your personal lock, with reference to the wrong drive event in the WHS register.
• Describe the belt end preparation, cementing, tie gum and joining steps and the checks for alignment and squareness before the press goes on.
• Describe the press set-up, cure temperature, pressure and time from the compound data sheet, the cool-down rule and how the edges are cured properly, with reference to the warranty repair in the nonconformance register.
• Complete the splice record and the job card, describe the handover to the customer and the slow speed run, and reconcile the crew box chemicals with the register on return.
