This Explosion-Proof Synchronous Lifting Electric Hoist is a specialized, high-performance system designed for the critical and demanding task of building large storage tanks in hazardous environments. It is primarily used for the "jack-up" method of tank construction, where the roof is lifted simultaneously by multiple hoists acting as synchronized jacks. Certified for use in explosive atmospheres, this system ensures maximum safety and operational integrity in oil & gas, petrochemical, and refining facilities where flammable vapors may be present.
Key Parameters:
Lifting Capacity | 10 tons to 100 tons per hoist (Typically used in arrays of 10+ hoists) |
Lifting Speed | 0.5 - 1.0 m/min (Precise and synchronized speed is critical) |
Synchronization Accuracy | ±10 mm (Across all hoists in the system) |
Explosion-Proof Rating | Ex d IIC T4 / ATEX or equivalent certification for hazardous zones. |
Control System | Centralized computerized control with PLC for automatic synchronization, real-time monitoring, and error |
Motor Power | 10 kW to 40 kW (Explosion-Proof Motor) |
Key Features:
Explosion-Proof Construction: All electrical components, including motor, control box, and pendant, are housed in certified explosion-proof enclosures to prevent ignition of surrounding gases.
Precise Synchronous Control: The advanced PLC-based system ensures all hoists lift at exactly the same rate, preventing any structural stress or deformation to the tank.
Real-Time Monitoring: The control room displays real-time data for each hoist (load, height, status), allowing operators to monitor the entire lift process.
High Safety & Reliability: Features overload protection, emergency stop for the entire system, and automatic halt in case of out-of-sync error or power failure.
Rugged Design: Engineered for outdoor site conditions, resistant to dust, moisture, and impact.
Applications:
Synchronous lifting of storage tank roofs, decks, and internal structures using the jacking method.
Construction and installation of large floating roof tanks in refineries and tank farms.
Any heavy lifting operation requiring precise synchronization of multiple hoists in potentially explosive atmospheres
