Q1: What is an Explosion Proof Single Girder Overhead Crane?

A: It is a single-girder electric overhead traveling (EOT) crane with all electrical and mechanical components certified to prevent ignition of flammable gases, vapors, or combustible dusts. It is used in hazardous environments such as chemical plants, oil refineries, grain handling facilities, paint shops, and pharmaceutical manufacturing areas.

Q2: What explosion protection methods are used on this crane?

A: Motors use flameproof enclosures (Ex d) that contain internal explosions. Control panels use pressurized (Ex p) or increased safety (Ex e) designs. Limit switches are encapsulated (Ex m) or intrinsically safe (Ex i). Wire ropes are anti-static, bumpers use non-sparking metals, and the entire crane is continuously grounded to dissipate static charge.

Q3: How do I select the correct explosion protection rating for my facility?

A: First, identify your hazardous zone: Zone 1 or 2 for gases, Zone 21 or 22 for dusts. Second, ensure the crane's T-Class is lower than the auto-ignition temperature of all substances present. T1 allows up to 450°C, T2 up to 300°C, T3 up to 200°C, T4 up to 135°C, T5 up to 100°C, and T6 up to 85°C – always choose the lowest applicable class for your environment.

APPLICATION

1.This crane is widely used in chemical and petrochemical plants where flammable liquids, gases, or vapors are handled, ensuring safe lifting of raw materials, reactors, and drums without risk of ignition.

2.It is essential for oil refineries and gas processing facilities, providing reliable overhead lifting for pump maintenance, valve replacement, and equipment installation in hazardous classified areas.

3.The crane is also critical in paint and coating workshops, where airborne solvent vapors create explosive atmospheres, allowing safe movement of pigment bins, mixing tanks, and finished product containers.

4.In pharmaceutical and fine chemical manufacturing, this crane operates safely in alcohol-based or solvent-rich production zones, handling intermediate chemical drums and reactor components without generating sparks.

FEATURES

Explosion proof certified construction – complies with ATEX, IECEx, or NEC standards

Spark-resistant components – includes copper-aluminum alloy friction parts, brass or stainless steel hardware, and anti-static chain or rope to eliminate ignition sources.

Sealed electrical system – all motors, control panels, limit switches, and pendants are fully enclosed in explosion proof enclosures to contain any internal arcing.

Temperature class rating – limits maximum surface temperature below the auto-ignition point of surrounding hazardous substances (e.g., T4 or T5 rating).
