Explosion proof performances of all motor, and electric components of explosion-proof crane satisfy standards stipulated by GH 3836.2--2000Explosion proof electric equipment Working in Explosive Gas Environment Part 2: Flame-proof Type "D", and the performance of the crane satisfies demands in used in JB/T5897--1991Explosion proof crane. The crane has obtained Explosion-proof certificate after passing examinations by units designated by the government to test explosion-proof products. The explosion-proof marks are Exd II, BT4, ExdII CT4 respectively.

This product is suitable for areas where the explosion-transmission is not higher than IIB or IIC and the ignition temperature group of inflammable gas or explosive mixture of steam and gas is not lower than T4. Applicable dangerous zones are zone 1 and zone 2. (please refer to GB 3836.1—2000 for details).

It is generally controlled on the ground, but control from the driver' cabin is also allowable. The working grade is intermediate.

(Note: 5-10t crane does not have an auxiliary hook.)
