  5. Working temperature: -25 to +40 ℃;

  6. Lift tool: hook (non-standard design is acceptable);

  7. Power supply: 3-phase 380V 50HZ (can be customized according to user needs);

  8. Large wheel diameter: 270MM, 300MM, 400mM (optional according to actual tonnage span).

  • Application:

This crane is a general-purpose crane, mainly used in chemical industry with low frequency of use or light lifting capacity, such as mechanical manufacturing, workshop, assembly, warehouses, material yard, etc.

  • Features:

  • This crane is suitable for use in flammable and explosive environments. Explosion proof grade dIIBT4.

  • Reasonable structure, beautiful appearance, and strong explosion-proof performance.

  • This crane has 3 control modes: pendent, cabin, and remote control. The cabin is also equipped with two forms of entrance, i.e. from top or side.

  • Notes:

  • This crane is suitable for explosive gas environments formed by combustible gases, vapors, and air in factories with explosion-proof levels not higher than B or C, and ignition temperatures not lower than T4 (135 ℃). The hazardous area used is Zone 1 or Zone 2, and it is not suitable for Zone 0.

  • Zone 0: A place where explosive gas mixtures occur continuously, frequently, or for a long time under normal circumstances.

  • Zone 1: Places where explosive gas mixtures may occur under normal circumstances.

  • Zone 2: Places where explosive gas mixtures cannot occur under normal circumstances, and only occasionally occur for a short period of time in abnormal situations where equipment malfunctions or operational situations may occur.
