Moulding points to tools that can identify the position from which a vibration originates and help establish whether it occurs once per wheel revolution or is associated with the drivetrain. This distinction can help technicians determine where further investigation is required. A vibration occurring once per revolution may direct attention towards the tyre and wheel assembly, including uniformity, while a disturbance associated with the drivetrain may require a different approach. The findings should be considered alongside checks for wheel damage and faults elsewhere on the vehicle, including the suspension and wheel bearings. The objective is to identify the source of the disturbance rather than repeatedly balancing or replacing components in an attempt to eliminate the symptom. A more targeted diagnosis For independent workshops, the key message is that balancing is only one part of diagnosing tyre-related vibration. Uniformity, flat spotting and irregular wear can all contribute to complaints that remain unresolved after conventional balancing. By combining an understanding of the symptoms with a detailed tread inspection, knowledge of the vehicle’s history and, where appropriate, specialist vibration analysis, technicians can narrow down the possible causes. A more targeted approach helps distinguish tyre-related problems from faults elsewhere on the vehicle, allowing workshops to make better-informed decisions about the next steps in the diagnostic process. www.bridgestone.com. Hofmann Megaplan has expanded its tyre equipment range with two new 28-inch automatic tyre changers. The Megamount 38 is designed as a capable all-rounder for busy professional workshops. Its automatic tilt-back column and powerful single-speed turntable provide straightforward, dependable operation, while its 9 to 28inch clamping capacity covers a broad range of workshop wheels. Supplied as standard, the HPX-DM assistance system uses pneumatically controlled dual rollers to support the technician when working with largediameter, low-profile, run-flat and ultrahigh-performance tyres. This makes the MM38 a practical option for workshops looking to handle increasingly demanding tyre constructions without moving into a higher equipment category. The defining feature of the Megamount 48 is its automatic vertical sliding column. Instead of tilting backwards, the column rises vertically, significantly reducing the rear clearance required and allowing the machine to be positioned closer to a workshop wall. The MM48 also features a motoinverterdriven turntable offering progressive rotation from 0 to 16rpm. Speed is controlled directly through the pedal, enabling the technician to slow the turntable through difficult sections and increase rotation as the job allows. A powerful hand-operated bead breaker, with conveniently positioned controls, provides additional precision when working with demanding wheel and tyre combinations. Both machines offer protected, adjustable jaws and bead-breaking capability for wheels up to 15 inches wide. Competitively positioned, the MM38 and MM48 allow businesses to select the level of technology that best matches their workload, available space and investment plans. www.hofmann-megaplan.co.uk Hofmann Megaplan expands tyre changer range
