HHBB Fixed Type Electric Chain Hoist

As one of Baiyi Lifting's core electric lifting products, this durable HHBB fixed type electric chain hoist addresses the shortcomings of manual hoists in heavy-load, high-frequency lifting applications and is a key piece of equipment for improving operational efficiency.

1. Body

The HHBB fixed type electric chain hoist is stamped from a single piece of mild steel plate with a thickness of 5-8mm, offering 40% greater deformation resistance than a modular hoist. Electrostatically sprayed plastic prevents rust and oil stains, and key bolts are reinforced and welds are polished, ensuring safety and durability.

2. Control System

The multi-function remote control features an ABS housing rated for -20°C to 60°C, silicone buttons for a comfortable feel, and an oil- and cold-resistant cable. This electric hoist features a fault alarm light, providing visual and audible warnings when overload or motor overheating occurs. The rated load and lifting speed are clearly marked for easy viewing.

3. Chain: Made of rolled 20Mn2 alloy steel, with a diameter of 6-18mm and a section length tolerance of ±0.2mm. The chain is galvanized to an 8-12μm thickness for rust resistance. The pins feature an interference fit and a cotter pin lock to prevent disconnection.

Nylon inner guide grooves reduce wear, and the curved inlet prevents jamming.

4. Protection: IP54 rated for dust and water protection, with automatic power-off at 155°C overheating. The terminal box is sealed, and the terminals are insulated to prevent electrical leakage.

Use Scenarios

1. Factory Workshops

The HHBB fixed type electric chain hoist can be fixed to workshop beams or custom steel frames for material transfer on production lines, heavy component installation and commissioning, and equipment maintenance. Its integrated frame resists deformation, and its low noise level of ≤65dB ensures smooth operation. Its remote control with inching adjustment (0.3m/min) ensures precise alignment, increasing efficiency eight times over manual hoists.

2. Warehousing and Logistics

This electric hoist is used for loading and unloading goods from high-bay shelves in warehouses, transferring pallets, and loading and unloading heavy packages. Its IP54 motor is dust- and splash-proof, and its galvanized chain is contaminant-resistant.

3. Special Industrial Environments

The explosion-proof model (meets Class IIA-IIB standards) can be used for disassembling hydraulic supports in underground coal mines and lifting raw material tanks in chemical plants. Its enclosed structure is suitable for hazardous locations. Its electrostatically sprayed plastic body and galvanized chain are corrosion-resistant and can withstand the acidic and alkaline mist environments of electroplating workshops. For example, two explosion-proof models can be used in coal mines to create dual lifting points, ensuring operational safety. 4. Low-Covered Spaces

The fixed bracket allows for quick installation in temporary workshops, basements, mezzanines, and other areas. HHBB fixed type electric chain hoist’s compact design maximizes the effective lifting height (3-12 meters), eliminating the need for complex rails and making it suitable for cargo lifting and high-bay storage in small warehouses.

Selection and Usage Considerations

1. Load and Height Selection: Select a model based on the maximum lifting weight (allow a 20% safety margin) and lifting height (1 meter higher than required). For example, for a 3-meter rack, choose a 4-meter lifting height.

2. Environmental Upgrade: Select a model with enhanced protection for humid or dusty environments. Explosion-proof models are required for hazardous locations to avoid illegal use.

3. Installation Specifications: The fixed bracket must be capable of supporting at least 1.5 times the rated load of the equipment. Installation and commissioning must be performed by professionals to ensure safe operation.
