LHB Explosion-proof Double Girder Hoist Overhead Cranes: Durable Solutions for Risky Environments

LHB explosion-proof double girder hoist overhead cranes are used in the working environment where explosive mixtures exist. The structure form of its main load-bearing components is similar to that of LH electric hoist double girder bridge cranes. The main difference is that the whole machine’s electrical equipment is used in explosion-proof type, and the power supply of the big vehicle adopts a flexible cable type power supply.

Product Features:

• In order to ensure the mechanical explosion-proof requirements, the working linear speed of each of its mechanisms are controlled within 25m/min.
• The rated lifting capacity is 5t~40t and the span is 7.5m~31.5m.
• The tread and rim of the wheel should be made of stainless steel or other non-sparking materials that do not ignite explosive gas mixtures due to impact and friction.
• 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 design for frequency conversion and speed regulation.
• The operation form is wired operation on the ground, and can also be designed for remote control operation on the ground.
• The machine is suitable for lifting and carrying operations in places where there are flammable, explosive or harmful gases 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 handling, flour mills and cement factories and other dusty environments.
