Motor and electrical appliances of this crane are explosion proof type. When explosion proof grade is ExdII CT4, travelling mechanism should do spark proof treatment. The whole machine meets standards of JB/T10219-2001 (Specification for explosion-proof cranes with electric wire rope hoist),explosion proof grade have ExdII BT4 and ExdII CT4 two kinds. It has characteristic of rational construction, perfect appeaance and strong Ex technical performace.

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.)
