Technical Parameters Overview

Explosion-Proof Design of Economical Explosion Proof Hoist Crane Double Girder

Safety in hazardous environments starts with the right design. Every part of the crane is built to reduce the risk of sparks and keep operations safe.

• Flameproof Electrical Components
  All motors, control panels, junction boxes, and wiring are sealed in explosion-proof housings.
  These enclosures are built to contain any sparks or arcs, so they won't ignite gases or vapors around them.
• Non-Sparking Materials Where It Matters
  Parts like wheels, cable rollers, and bumpers are made of copper or other non-sparking materials.
  This helps prevent ignition from friction or impact during movement.
• Stainless Steel Wire Ropes for Higher Gas Groups
  For areas with IIC-class gas hazards, the crane can be equipped with stainless steel wire ropes.
  These are more resistant to wear and won't create sparks, even under stress.
• Built to Chinese Explosion-Proof Standards
  The whole system is designed according to GB3836.1 and GB3836.2.
  These standards are widely accepted for explosion protection in industrial applications.

This design ensures the crane performs safely and reliably—even in risky working environments with gas, dust, or chemical exposure.

BCD Explosion-Proof Hoist Trolley

The hoist trolley is the heart of the lifting system. For explosive environments, every detail matters. That's why this trolley is designed with both safety and performance in mind.

BCD Explosion-Proof Hoist Trolley

• Equipped with flameproof motors and enclosures
• Constructed using anti-sparking materials for enhanced safety
• Available in single-speed or double-speed hoisting options
• Designed for smooth travel and reliable lifting performance

Ask for economical explosion proof hoist overhead crane price

• Flameproof Motors and Enclosures
  The hoist uses explosion-proof motors that are sealed to prevent sparks.
  All electrical parts are housed in flameproof enclosures to avoid any fire risk.
  These motors are built to last and stay cool even during long use.
• Safe, Anti-Sparking Materials
  The trolley frame and moving parts are made of non-sparking materials, like copper alloys or stainless steel.
  This reduces the chance of friction sparks while the trolley moves or lifts.
  Great for areas with gas, vapor, or dust hazards.
• Flexible Speed Options
  You can choose between single-speed or double-speed hoisting.
  Single-speed is simple and reliable.
  Double-speed gives you more control—slow for precise lifting, fast for daily tasks.
• Stable Movement and Performance
  The trolley is engineered to travel smoothly along the crane girders.
  Even under load, it stays stable and easy to control.
  It's tested for consistent lifting without sudden jerks or delays.

This explosion-proof trolley is not one-size-fits-all. It can be adjusted to suit your specific lifting height, speed, and usage needs

Double Girder Explosion Proof Overhead Crane with Main and Auxiliary Hoists

For jobs that require more than just simple lifting, a dual-hoist setup can make a real difference. This configuration adds flexibility and control to your crane system.

• Dual hoist configuration available for enhanced functionality
• Main hoist handles heavy loads; auxiliary hoist supports precision tasks or lighter lifting
• Independent controls enable flexible and efficient operation
• Ideal for processes requiring multi-stage or delicate lifting operations

Ask for economical explosion proof hoist overhead crane price

• Dual Hoist Setup
  The crane can be fitted with both a main hoist and an auxiliary hoist.
  This setup is useful when lifting operations involve more than one task.
  It helps you switch between heavy and light loads easily.
• Different Roles, Same Crane
  The main hoist is built for handling the heavier loads.
  The auxiliary hoist is used for lighter tasks or when precision is needed.
  It's a good fit for positioning components, feeding materials, or slow lifts.
• Independent Operation
  Each hoist works with its own control system.
  This means you can operate them one at a time or in combination.
  It adds flexibility and saves time during complex operations.
• For Complex or Delicate Lifting
  This dual-hoist setup is ideal for industries that require multi-step lifting.
  It's especially helpful in tasks like loading sensitive equipment or placing parts in exact locations.

Whether your job involves heavy-duty lifting or more careful handling, this combination hoist setup helps you do both—without changing equipment.

Dual Explosion Proof Wire Rope Hoist Trolley Configuration for the Explosion Proof Overhead Cranes

When lifting gets more complex, having two trolleys on one bridge can really help. This setup gives more control and options in tight or demanding workspaces.

• Two independent hoist trolleys mounted on the same bridge
• Enables simultaneous or separate operation for handling wide or multiple loads
• Suitable for facilities requiring parallel or complex lifting tasks
• Supports a combination of different hoist types and speeds if required

Ask for economical explosion proof hoist overhead crane price

• Two Trolleys, One Crane
  The crane can be equipped with two separate hoist trolleys, each running independently on the same bridge beam.
  This allows you to lift from two different points at the same time—or operate one while the other stands by.
• More Flexible Lifting
  You can use the trolleys together or separately, depending on the task.
  For example, lift a long, wide load using both hoists, or run two jobs in the same bay without moving the crane again.
• Perfect for Complex Operations
  This setup is great for workshops or plants where parallel handling is common—like in equipment assembly, mold flipping, or pipe installation.
  It saves time and reduces the need for extra lifting gear or repositioning.
• Custom Combinations Possible
  Each trolley can have different lifting capacities, speeds, or hoist types, if needed.
  One can be optimized for heavy, single-speed lifting, while the other handles lighter or more delicate jobs with dual-speed or frequency conversion.

If your operations require precision, space efficiency, or multi-point lifting, the dual trolley configuration is a smart and reliable choice.

Application Areas

Explosion-proof overhead cranes are not for general use. They're built for tough, risky environments where safety is everything. These cranes are often used in areas where flammable gases, vapors, or dust are present in the air.

Here are some of the common places where they're put to work:

• Oil and Gas Refineries
  For moving equipment or materials near flammable liquids and gases.
• Petrochemical Processing Plants
  Used in production zones where chemical reactions generate hazardous atmospheres.
• Chemical Storage and Handling Facilities
  Ideal for safely lifting drums, tanks, and materials in chemical warehouses.
• Paint and Coating Manufacturing
  Helps transport solvents and coating products without the risk of ignition.
• Gas Cylinder Workshops
  For handling filled or empty gas cylinders under strict safety requirements.
• Cement and Flour Mills
  In dry and dusty areas where airborne particles could ignite.
• Hazardous Material Warehouses
  Supports daily lifting tasks while keeping explosion risks under control.

If your facility handles flammable or dusty materials, these cranes are built to make lifting safer and more reliable.
