Universal electric hoist

Product Overview
Operator safety, load control, and equipment protection are the foundational engineering pillars of the Weiyuan Heavy Duty Electric Hoist. Hoisting heavy loads overhead inside active industrial environments demands zero tolerance for mechanical or electrical failure. The Weiyuan Electric Hoist incorporates a comprehensive multi-tier safety architecture, combining electronic overload limiters, dual-stage limit switches, fail-safe automatic brakes, and thermal motor protections. With low-voltage 24V/36V operator controls and an emergency power cut-off system, this hoist prevents load drops, structural over-stressing, and electrical hazards in modern safety-focused industrial facilities.

Product Advantages
Dual-Stage Upper & Lower Limit Switches: Equipped with a mechanical fire-stop cross limiter that cuts main motor power immediately if the hook reaches upper or lower travel boundaries.
High-Precision Electronic Overload Limiter: Features an integrated load sensor that monitors lifting tension in real time, triggering audio-visual alarms and cutting the “UP” circuit at 105% load.
Fail-Safe Automatic Brake System: The high-torque brake automatically engages the moment power is cut or the pendant button is released, holding suspended loads securely with zero drift.
Low-Voltage Operator Controls (24V/36V): Control pendants and wireless receivers operate on safe low voltage, protecting operators against electric shock risks in humid environments.
Anti-Phase & Thermal Motor Protection: Protects against phase sequence reversal (preventing reverse motor direction) and includes bimetallic thermal sensors to avoid coil overheating.

Application Scenarios
High-Density Assembly Plants: Safely moves heavy structural modules over active assembly lines without risking dropped loads or unexpected drifting.
Foundry & Smelting Workshops: Equipped with heat shields and flame-retardant electrical cables for transferring hot metal ladles and foundry flasks.
Chemical & Flammable Fluid Storage: Configurable with explosion-proof enclosures (Ex d IIB/IIC) and non-sparking bronze hooks for volatile chemical bays.
Heavy Maintenance & Overhaul Bays: Provides safe, controlled micro-inching during the disassembly and alignment of heavy industrial gearboxes.
Public Infrastructure & Water Treatment Plants: Ensures reliable, moisture-sealed lifting operations over outdoor water pumps, valves, and filtration sluice gates.

FAQ

1. What’s the information should I provide when inquiry?
   More details or drawings, better. A: Lift capacity B: Lifting height C: Specific safety requirements (e.g., overload limiter, explosion-proof class, dual brakes) D: Material to lift E: Power source.
2. How many operating methods for my selection?
   Standard operating methods: A: Low-voltage pendant controller with emergency stop button. B: Wireless remote control. Choose any type as you like.
3. How does the overload limiter protect the hoist?
   The load sensor continuously measures tension. If the load exceeds 100%, a warning sounds; at 105% rated load, it automatically cuts the “UP” circuit while allowing the operator to lower the load safely.
4. What about warranty time?
   Use within the standard for the next 12 months under proper operational care.
5. How can we install the hoist?
   Our technical engineers provide clear wiring schematics, limit switch adjustment guides, and complete safety commissioning instructions.
6. May I visit your factory?
   Of course. We can pick you up at train station, high-speed rail station or airport, and book hotel for you.
