Ponts roulants monopoutres antidéflagrants LB : adaptés aux environnements dangereux

LB electric explosion-proof single girder overhead crane is used in the working environment where explosive mixtures exist. The structure of its main load-bearing components and LD electric single girder overhead cranes are the same. The main difference is that the entire electrical equipment are used in explosion-proof type, and the power supply of the trolley is supplied by flexible cable.

Product features:

• The rated lifting capacity is 1t~20t and the span is 7.5m~22.5m.
• In order to ensure the mechanical explosion-proof requirements, the working linear speed of each mechanism is controlled within 25m/min.
• Wheel tread and rim part should not be due to impact, friction and ignition of explosive gas mixtures of stainless steel or other non-sparking material production
• The small rollers on the cable trolley and the small bumper wheels on the limit switch are made of copper.
• The power supply of the big vehicle adopts the flexible cable type power supply, and the hoist traction line adopts stainless steel wire rope in the case of IIC class.
• The working speed of each organization: the trolley and trolley running mechanism is single-speed, the hoisting mechanism can be single-speed or double-speed, and each organization can also be non-standard designed for frequency conversion speed regulation.
• Operation form for the ground wired handle operation, can also be designed for the ground wireless remote control operation.
• The machine is suitable for lifting and carrying operations in places where flammable, explosive or harmful gases exist in the working environment. For example, it is widely used in many industries, such as petroleum extraction, oil refining, natural gas processing, chemical material storage tanks, flour mills and cement factories, and many other dusty environments.
