LXB: explosion‑proof LX for explosive gas atmospheres. Uses HB/HBS hoists, with explosion‑proof electricals and non‑sparking (stainless) wheel materials. Ratings: 0.5–16 t, span 3–16 m, class A3–A4, –25 ℃ to +40 ℃, ExdⅡBT4/CT4. Floor controlled (pendant/remote). For chemical plants, petroleum depots, and similar hazardous locations.



The LXB crane retains the suspended I‑beam design of the standard LX model while incorporating comprehensive explosion‑proof features. All electrical components, including motors, control devices, and limit switches, are certified to flameproof enclosure standards (Ex d), ensuring that any internal sparks or arcs are contained and cannot ignite the surrounding explosive atmosphere. The hoisting mechanism can be equipped with HB (BCD) or HBS (BMD) explosion‑proof electric hoists, or alternatively with explosion‑proof chain hoists, depending on the specific application requirements. To prevent friction‑induced sparks, the wheel treads and flanges are made of stainless steel or other non‑sparking materials. Key technical parameters include rated capacities from 0.5 to 16 tonnes, spans from 3 to 16 metres, and duty classes A3–A4. The crane operates within an ambient temperature range of –25 ℃ to +40 ℃, with explosion‑proof ratings available up to ExdⅡBT4 (suitable for Zone 1 and Zone 2 with T4 temperature class) or ExdⅡCT4 (for even more hazardous gas groups). Standard control is floor‑based, with the choice of wired pendant or wireless remote operation. The LXB crane is widely deployed in chemical plants, petroleum depots, petrol stations, and other locations where flammable gases or vapours may be present.
