Compliant Explosion-Proof Design: Utilizes a combined flameproof, increased safety, and intrinsic safety explosion-proof technology. Achieves explosion-proof ratings up to Ex d IIB T4 / CT4, eliminating spark and electrostatic risks. Ideally suited for flammable gas environments in petrochemical industries and holds national explosion-proof certification.
Corrosion-Resistant & Durable Construction: Features anti-corrosion painting and rust-proof treatment on the frame to withstand corrosion from chemical gases and oil products. Offers ingress protection up to IP66, ensuring long-term stable operation in humid and corrosive conditions.
Multi-Level Safety Protection: Equipped with overload protection, upper and lower limit switches, explosion-proof brakes, door-machinery interlocks, and more. Electrical components meet controlled temperature standards, preventing lifting accidents at the source and ensuring safety in high-risk operations.
Stable, Efficient & Adaptable Performance: European-style lightweight design ensures smooth, low-noise operation and precise positioning. Adaptable for precision maintenance of chemical equipment and high-frequency lifting tasks, compatible with on-site intelligent management systems.
