QB Explosion Proof Overhead Crane

Présentation du produit

QB explosion proof overhead crane is a kind of lifting equipment designed for flammable and explosive gas or dust environments. Its main parts are made of explosion-proof structure and materials, which meet the strict requirements of the country and the industry for the explosion-proof level. It is widely used in the petroleum, chemical industry, natural gas, military industry, pharmaceutical industry, and other special industries that have very high requirements for safety.

QB Explosion Proof Overhead Crane

The explosion-proof performance of all motors and electrical appliances of the explosion-proof hook overhead crane complies with GB3836.2-2000 “Explosion-protected electrical equipment for explosive gas atmospheres - Part 2:Flameproof enclosure 'd”. The overall performance of the crane complies with the provisions of the standard JB/T5897-2006 "Explosion-proof overhead cranes". The explosion-proof marks are ExdIBT4 and ExdICT4, respectively.

Components of Explosion Proof Overhead Crane

• Main beam and end beam: double beam structure, welded with high-quality steel, optional anticorrosion coating treatment;
• Explosion-proof electric hoist or hoisting mechanism: the core components in line with the explosion-proof norms, lifting capacity of 5 ~ 100 tons above;
• Running mechanism: including explosion-proof drive motor, explosion-proof brake, and reducer;
• Electronic control system: explosion-proof electrical control box, cable, explosion-proof switch, explosion-proof lighting system;
• Safety system: explosion-proof Limiters, anti-collision devices, load limiters, and so on.

Explosion-proof electric hoist type selection:

Weihua can recommend the most suitable type of explosion-proof electric hoist according to the customer's actual application environment, helping your enterprise to improve operational efficiency and maintenance convenience.

• BCD type explosion-proof electric wire rope hoist: suitable for medium load conditions, using high-strength wire rope, with good stability and durability.
• BMD type explosion-proof electric wire rope hoist: has a double-speed switching function, in the lifting process, can be switched according to the needs of fast or slow mode, suitable for accurate positioning and flexible lifting has high requirements for application scenarios, such as precision equipment installation, easy-to-shake material handling, and so on.
• Explosion-proof low headroom hoists: designed for plants with restricted lifting space or working areas with limited structural height, the compact structure effectively reduces the overall height of the machine and improves the utilization rate of the lifting height, which is suitable for special environments such as clean rooms, laboratories, and underground pipe corridors.
• HB type explosion-proof two-speed electric hoist: combining the explosion-proof performance of BCD and the two-speed function of MD, it supports precise lift control and load fine-tuning operation, and it is suitable for explosion-proof areas with higher requirements for smoothness and safety of operation, such as chemical plant workshops, dangerous goods packaging areas, and so on.
• New Design Explosion-Proof Hoist: Adopting a modularized design, it is equipped with intelligent monitoring, a variable frequency drive, and automatic fault diagnosis, among other features. This hoist offers advantages such as a high protection level, low noise, and long life, making it widely used in heavy-duty, multi-frequency operation or intelligent factory scenarios.

Application

QB explosion proof overhead cranes offer excellent explosion-proof performance and reliability, making them the ideal solution for material handling in hazardous areas. It is widely used in various industrial environments that require a high safety level. The following are its typical application industries and scenes:

• Petroleum refineries: used in crude oil storage tanks, oil refining equipment lifting.
• Chemical production workshop: handling containers and equipment of flammable gases and chemicals.
• Natural gas stations and filling stations: pressure vessel or pipeline installation operations.
• Pharmaceutical industry: used in clean rooms where dust or organic solvents exist.
• Military and arms warehouses: high-risk material handling environments that require strict explosion-proof requirements.
