Lifting hook
Technical Specification: Explosion-Proof Electric Wire Rope Hoist Crane
This crane is designed with fully explosion-proof motors and electrical components. For models certified to the ExdII CT4 protection level, the travelling mechanism includes additional spark-proof treatment. The complete system complies with the Chinese standard JB/T10219-2001 (Specification for Explosion-Proof Cranes with Electric Wire Rope Hoist) and is available in two primary explosion-proof classifications: ExdII BT4 and ExdII CT4. It features a robust, integrated design and reliable explosion-proof performance.
Application Scope
This equipment is suitable for operation in hazardous locations where explosive gas atmospheres of transmission class IIB or IIC may be present, and where the ignition temperature group (T-Class) of flammable gases or vapors is not below T4. It is approved for use in Zone 1 and Zone 2 hazardous areas as defined by GB 3836.1-2000.
Operation & Duty Class
The crane is supplied with standard pendant (ground) control, with an operator's cab available as an option. It is rated for intermediate duty service.
(Note: Models with a capacity of 5 to 10 tons are not equipped with an auxiliary hook.)
Standard Configuration
Control Interface: Operator's Cab.
Hoisting Unit: Explosion-Proof Electric Hoist.
Drive Components: Reducer and motor are configurable and can be sourced from leading manufacturers or specified by the client.
Electrical System: Key components are selectable based on customer requirements.
Key Features & Advantages
High-protection safety design.
Accurate positioning and reliable operation.
Smooth acceleration, travel, and deceleration.
Simplified installation, routine maintenance, and disassembly.
Easy access and replacement of wear parts.
Cost-effective performance in demanding environments.
Engineered for deployment in environments with potential flammable gases, vapors, or combustible dusts, this explosion-proof single girder overhead crane provides essential material handling safety for high-risk industries. Its compact and certified design supports operations in the following key sectors:
1.Petrochemical & Oil Refining
Moving materials, equipment, and components in areas containing volatile hydrocarbons, solvents, and process gases during production, storage, and maintenance.
2.Pharmaceutical & Chemical Manufacturing
Enabling safe transport of raw materials, intermediates, and finished goods in zones where explosive atmospheres may arise from alcohol vapors, solvent emissions, or fine chemical powders.
3.Paint & Coating Facilities
Suitable for use in spray booths, mixing rooms, and storage sections where flammable paint vapors, thinners, or powder coatings are present.
4.Oil & Gas (Upstream & Midstream)
Used in onshore/offshore modules, compressor stations, and gas processing plants for equipment handling and maintenance within Zone 1 and Zone 2 hazardous areas.
5.Wastewater & Biogas Treatment Plants
Handling equipment and materials in digesters, sludge processing zones, and biogas collection areas where methane (CH₄) and hydrogen sulfide (H₂S) pose explosion hazards.
