Universal electric hoist
Electric Hoist — Certified Lifting Equipment for Hazardous-Area Operations
Standard electric hoists aren’t rated for use anywhere flammable gases, vapors, or combustible dust may be present. For petrochemical, chemical, and other classified hazardous-area facilities, an explosion-proof electric hoist is a compliance requirement, not an upgrade option.
Product Description
An explosion-proof electric hoist is built around the same core lifting mechanism as a standard wire rope or chain hoist, but with motors, electrical enclosures, control panels, and wiring specifically designed and certified to prevent ignition of surrounding flammable atmospheres. Certification is tied to the specific hazardous-area zone classification of the installation site, so specification begins with the facility’s own zoning documentation rather than a generic “explosion-proof” label.
Key Features and Advantages
- Certified ignition-proof electrical components — motors, enclosures, and control panels rated to the required explosion-protection standard.
- Anti-static structural design, reducing the risk of static-discharge ignition sources across the hoist body.
- Available in both wire rope and chain hoist formats, across the same broad capacity range as Weiyuan’s standard hoists.
- Sealed, corrosion-resistant construction, suited to the chemical-exposure conditions common at petrochemical sites.
- Documented certification package provided for facility compliance and import/inspection requirements.
Technical Specifications
| Parameter | Range |
|---|---|
| Lifting capacity | 0.5–32 tonnes (wire rope or chain format) |
| Explosion-protection rating | Configurable to required Zone/Class classification |
| Lifting height | Up to 30 metres depending on format |
| Power supply | 380V/50Hz (customizable) |
| Duty class | M3–M8 depending on format and capacity |
| Enclosure protection | IP65 or higher standard |
Customization Options
Explosion-proof hoists are specified according to the exact hazardous-area zone and gas/dust group of the installation site, which determines motor and enclosure rating. Additional options include corrosion-resistant coatings for chemical-exposure environments, low-headroom trolley configurations, and variable-speed control for precision lifts near process equipment.
Applications
Explosion-proof electric hoists are required equipment in petrochemical plants, chemical storage and blending facilities, oil and gas processing sites, paint and solvent handling areas, and any facility with a formally classified hazardous area under its safety zoning documentation.
Safety & Compliance
Every explosion-proof hoist is built to the specific zone and gas-group classification confirmed at the quotation stage, with certification documentation provided for the buyer’s facility compliance records. Standard safety features — overload protection, travel limit switches, calibrated load-bearing components — are retained in addition to the explosion-protection rating.
Case Study: Equipping a Chemical Storage Facility’s Zoned Area
A chemical storage and blending facility needed a hoist for drum and container handling within a formally zoned hazardous area, where standard electrical equipment was not permitted under the site’s safety documentation. Weiyuan specified a hoist with motor, enclosure, and control-panel rating matched to the facility’s declared zone classification, along with anti-static structural measures throughout. The unit passed the facility’s compliance inspection and has been in service within the zoned area without incident.
Installation and Support
Installation includes verification that the hoist’s certified rating matches the installation zone before commissioning. Weiyuan provides certification documentation, installation guidance, and technical support for facility compliance reviews.
Pricing and Quotation
Pricing depends on capacity, required zone/gas-group rating, and hoist format (wire rope or chain) — Weiyuan quotes based on the facility’s specific zoning requirements rather than a generic explosion-proof price tier. [Get a Quote →]
Delivery Cycle
Standard zone-rated configurations: approximately 30–40 days. Higher-rated or fully custom certification requirements: approximately 45–60 days.
FAQ
How do we know what explosion-protection rating we need? The required rating is determined by your facility’s own hazardous-area zoning documentation (zone/class and gas or dust group) — this should be confirmed with your site’s safety engineer before requesting a quotation.
Is an explosion-proof hoist available in both wire rope and chain format? Yes, both formats are available with explosion-proof certification across most of the standard capacity range.
Does the explosion-proof rating affect lifting speed or capacity? No — explosion-proof hoists are engineered to match the lifting performance of their standard equivalents; the certification applies to ignition-source protection, not mechanical performance.
