explosion proof double beam eot crane,
anti-explosion double girder overhead crane---
Application: it's used to transport goods in the inflammable and explosive environment.
Brief introduction: According to GB3836.1-2000and GB3836.2-2000, motor and electrical appliances of explosion proof wire rope electric hoist are explosion proof type. When explosion proof grade is Exd CT4, travelling mechanism should do spark proof treatment. The whole machine meets standards of JB/T10222-2001, explosion proof grade have Exd BT4 and Exd CT4 two kinds. It can be installed under workshop fixed spending rail to use individually and can be used together with LXB explosion proof electric suspension single girder crane, LB explosion proof electric single girder crane and explosion proof electric hoist double girder crane. The capacity is 1t-32t, working environment temperature is -25°C~40°C.
