IP67 protection rating: Provides dustproof (complete protection against dust intrusion) and waterproof (can be briefly immersed in water), enabling it to withstand outdoor, humid, and dusty engineering environments. This reduces the probability of electrical component damage due to environmental factors and extends equipment lifespan.
Clear start/stop buttons: The simple and intuitive operation logic reduces the learning curve for operators and improves work efficiency.


Featuring an orange, industrial-grade exterior design, it is equipped with a push handle and operating lever for easy manual movement and operation. It balances operational stability with the feasibility of manual handling.
The 3KW push-type motor uses a 20A single-phase 230V three-core industrial plug.
