Solution

For scenarios involving fragmented maintenance tasks and hard-to-reach areas that cannot be covered by stationary cleaning equipment, we provide a handheld laser cleaning supplementary solution. This solution is suitable for applications such as on-site maintenance in vehicle depots, track-side maintenance, and pre-treatment before repainting small components. The equipment is portable and easy to transport, requires no complex installation, and can rapidly respond to temporary cleaning needs. As a complementary tool to automated cleaning lines, it ensures comprehensive cleaning coverage across all operational scenarios.

Working Principle

(1) Introduction The equipment transmits high‑energy laser to the handheld cleaning head via optical fiber. Operators hold the cleaning head and aim it at the workpiece surface. The laser beam acts on the dirt layer to heat it for vaporization, expansion and stripping. Built‑in parameter adjustment function allows the equipment to adjust laser energy according to different materials and dirt thicknesses. A supporting portable dust‑removal device collects smoke and dust generated during operation to realize flexible mobile non‑contact cleaning work. (2) Process Flow Chart Equipment startup and commissioning → Aiming at the operation area → Cleaning with uniform‑speed movement → Surface purging and cleaning → Effect inspection → Operation completion

Why Choose Us

Lightweight and easy to operate

The handheld laser head weighs only 0.8 kg, offers a comfortable grip, and is suitable for complex operational scenarios such as high-altitude work, confined spaces, and under-vehicle inspections—increasing under-vehicle maintenance efficiency by 300%.

Excellent cleaning performance

The rust removal efficiency reaches 1.5 m²/h, which is three times that of traditional manual grinding, and delivers exceptional results in removing thin paint layers and surface rust.

Long battery life and excellent compatibility

The integrated battery pack supports continuous operation for over 4 hours, enabling a single charge to cover up to 30 linear meters of rail de-rusting, thereby meeting on-site operational requirements.

High protection rating and robust operational performance

It achieves an IP54 protection rating, is resistant to dust and vibration, and can extend the equipment's service life by up to 5 years under harsh operating conditions.
