Alf-A7 Push-Button Chassis Shaker for Auto Suspension and Noise Diagnosis

Alf-A7 Push-Button Chassis Shaker for Auto Suspension and Noise Diagnosis. 4,000 kg (8,800 lb) working load, verified under 4,800 kg (10,600 lb) wheel load before shipment. Dual 2.2 kW (3 hp) two-stage motors deliver stable vibration from 0 to 200 cycles per minute. Mechanical control panel with push buttons and dials - no software, no menus, and standard industrial parts that any workshop can replace. Reproduces real road conditions under a stationary vehicle, so chassis noise and suspension faults can be traced inside the bay. Hot-rolled steel wheel fasteners and a high-load screw height adjuster hold position under repeated load cycles. Swivel casters let one set serve more than one bay position. OEM branding and panel labels customizable.
