1 t 2 t 3 t-proof monorail car, aluminum bronze proof tools work in a concentration of 7.8% ethylene gas does not explode; beryllium proof tools work in a concentration of 21% hydrogen does not cause an explosion, because beryllium zero magnetic material Therefore, also known as beryllium bronze proof tools magnetic tools, can work in a magnetic field environment. Hebei Titans produced the explosion was small pulley and chain hoists supporting the use, there are chain-action and push two, chain-acting small drive pulley is pulling the chain hoist and travel goods, hand push small pulley is driven by hand hoist and cargo travel, compared to the chain moving than push to look easy, but the price is relatively high number. Explosion small pulley tool for explosive gas areas, made of aluminum bronze, beryllium copper alloys. Hebei lifting Titans ready to welcome your arrival!
