Product Introduction of Henan Mine Crane Manufactured Explosion-Proof Electric Hoist Cranes
Explosion-proof electric hoist cranes are core equipment ensuring operational safety in flammable and explosive hazardous environments. With advantages of “high safety compliance, high stability and durability, and high cost-effectiveness,” coupled with comprehensive quality service and assurance systems, they have become the preferred brand for: underground mining explosion-proof lifting equipment, and dust-proof electric hoists for flour mills. Specifically engineered for explosive gas environments and combustible dust atmospheres, it precisely addresses the pain points of traditional explosion-proof equipment—such as inadequate explosion protection, frequent maintenance, and low energy efficiency.
explosion-proof electric hoist
1. Core Features: Fortifying Safety Defenses in Hazardous Environments
(1) Comprehensive Explosion-Proof Compliance, Zero Safety Blind Spots
Equipment employs flameproof enclosure design, with explosion-proof casings rated for ≥1.5MPa pressure resistance and flange joint gaps controlled at 0.1-0.3mm to effectively contain internal flames. Explosion-proof ratings cover EXd BT4, EXd IIC T4 (gas explosion protection), and tD A21 IP65 (dust explosion protection), with temperature classes reaching T4-T6. Maximum surface temperature ≤85°C remains well below the ignition temperatures of flammable gases like hydrogen and methane, eliminating ignition risks at the source. Fully compliant with underground coal mine methane concentration requirements ≤1%, the dedicated underground coal mine explosion-proof electric hoist model has obtained MA/KA dual certification, ensuring suitability for various high-risk scenarios.
(2) Efficient and Stable Operation with Significant Cost Savings
Equipped with BZD series explosion-proof motors ranging from 0.4 to 13 kW, maintaining stable speeds of 1380-1400 r/min. Paired with integrated hardened gear reducers, transmission efficiency reaches 94.7%, reducing energy consumption by 20% compared to standard industry models.
(3) Flexible Scenario Adaptability and Modular Maintenance
Supports installation with single-girder or double-girder cranes, or standalone operation. Compatible with 10-63C I-beam tracks and minimum curvature radii of 0.8-11m, adapting to diverse environments including underground confined spaces, chemical workshops, and flour mill warehouses. Explosion-proof electric hoist customization allows adjustment of lifting capacity, height, and control methods per scenario, enabling “one machine for multiple applications.”
(4) Smart Safety Empowerment for Hassle-Free Operation
Integrated with an intelligent safety monitoring system, it continuously tracks critical parameters including motor temperature, bearing vibration, load capacity, and ambient gas concentration. When gas levels reach 20% of the lower explosive limit or component temperatures exceed thresholds, the system immediately triggers power shutdown, locks the brake, and activates audible/visual alarms. Simultaneously, data is transmitted via CAN bus to a remote platform. with a fault prediction accuracy exceeding 92%, enabling proactive mitigation of risks like motor overheating and wire rope wear.
(5) Quality Service & Assurance: Full-Cycle Worry-Free Support
Guided by Henan Mining’s philosophy of “Quality Builds Brands, Integrity Weaves the Future,” we’ve established a tripartite assurance system integrating “Quality Control – Service – Parts” to deliver full-lifecycle support from procurement to decommissioning.
Service coverage includes over 480 sales and service outlets worldwide, complemented by a 24/7 emergency hotline and tiered response protocols.
Spare parts are secured through 120 global warehouses maintaining 98% core component stock levels. Non-human-induced damage during warranty periods qualifies for free replacement, ensuring comprehensive safety and stability for explosion-proof electric hoist cranes.

Operating Manual for Shipbuilding Gantry Cranes Manufactured by Henan Mine Machinery
China's premier crane manufacturer, driving high-quality development in the crane industry for 24 years
-
Each crane must display a rated load capacity plate in a conspicuous location.
-
No personnel are permitted on the girder during operation, nor may the hook be used to transport persons
-
Operation is prohibited without a valid operator's license or under the influence of alcohol.
-
Operators must maintain full concentration during operation; talking, smoking, or engaging in unrelated activities is strictly forbidden.
-
Keep the crane clean and tidy; do not store equipment, tools, flammable materials, explosives, or hazardous substances haphazardly.
-
Do not overload the crane.
-
When operating along obstacle-free paths, the hook, lifting device, or bottom surface of the load must remain at least 2 meters above ground level. When crossing obstacles, the load must clear the obstacle by at least 0.5 meters
-
For loads under 50% of rated capacity, both lifting mechanisms may operate simultaneously. For loads exceeding 50% of rated capacity, only one mechanism may operate.
-
.For bridge cranes equipped with main and auxiliary hooks, do not simultaneously raise or lower both hooks (except under special circumstances).
-
Welding or hammering on suspended loads, or working beneath suspended loads, is prohibited (except when properly supported).
-
Inspection or maintenance work may only be performed after power has been disconnected and a “Do Not Operate” sign is displayed on the power switch. If live work is unavoidable, implement safety measures and assign dedicated supervision.
-
Do not throw objects from the vehicle indiscriminately.
-
Regularly inspect limit switches and interlock protection devices.
-
Do not use limit switch impact as a stopping method.
-
Do not lift or lower loads when hoist brakes malfunction.
-
Do not operate the hoist above personnel or equipment.
-
When welding any part of the crane, use a dedicated ground wire; do not use the crane body as a ground.
-
When the hook is at its lowest position, ensure at least two full turns of safety rope remain on the drum.
-
Cranes must not collide with each other; using one crane to push another into operation is strictly prohibited.
-
When lifting heavy objects, molten metal, explosives, or hazardous materials, first slowly raise the load 100–200 mm off the ground to test brake reliability.
-
Maintenance and inspection lighting must operate at voltages below 36V.
-
All electrical equipment enclosures on bridge cranes must be grounded. If trolley rails are not welded to the main girder, grounding measures must be implemented. Grounding conductors may use galvanized flat iron with a cross-sectional area exceeding 75mm², bare copper wire of 10mm², or galvanized round steel exceeding 30mm². The operator's cab or crane body shall have more than two grounding points. The grounding resistance from any point on the crane to the power supply neutral point shall be less than 4Ω.
