Wire rope electric hoist: a good helper for aerial transportation in construction
On construction sites, electric wire rope hoists suspended between concrete beams and columns become a valuable tool for construction. The green main unit acts as a "powerhouse," effortlessly lifting and lowering heavy objects through the strong wire rope and hook.
For applications such as masonry work and the transfer of small building materials, it requires no complex layout and can be quickly deployed by relying on the building's load-bearing structure. With simple operations, workers can precisely deliver bricks, construction tools, and other equipment to their target locations, reducing the labor of manual handling while significantly accelerating construction progress and ensuring stable and efficient on-site operations.
Strong lifting performance, suitable for heavy-duty applications.
It can carry weights ranging from several hundred kilograms to tens of tons (some models can lift 1-50 tons), surpassing the lifting capacity of electric chain hoists of the same specifications. It utilizes high-strength imported steel wire rope (such as models with a tensile strength of 2160N/㎡), which offers excellent tensile and wear resistance and a long service life. It is particularly suitable for heavy vertical lifting of large equipment, building components, and other equipment. Comprehensive safety protection and effective risk control.
Equipped with multiple safety devices:
Limit protection: Gear-driven upper and lower limiters precisely cut off the power circuit when the hook reaches its limit position, preventing overshoot or excessive lowering.
Overload protection: An electronic overload protector automatically cuts off the hoist circuit when the wire rope tension exceeds 105% of the rated value, preventing overload.
Reliable braking: Dual-disc electromagnetic disc brakes automatically engage upon power failure to prevent load slippage. The braking torque is no less than 1.8 times the rated torque of the motor. The brake clearance is self-adjusting and maintenance-free. Select models will automatically alarm when the brake pads become thin.
Additional protection: Anti-hook slippage, anti-rope loosening, and motor overheating protection further reduce operational risks. Excellent structural design and adaptability to various spaces.
Modularity + Compactness: The hoisting motor, reducer, and drum are integrated into a compact design, saving space. Some models (such as the European and New Chinese styles) feature a lightweight design. The aluminum alloy reducer housing is not only lightweight and corrosion-resistant, but also ensures smoother operation and lower noise.
Anti-Rope Design: The large-diameter drum and wear-resistant, self-lubricating rope guide (made of engineering plastic or ductile iron) effectively prevent the wire rope from tangling and loosening, extending its lifespan. This design also reduces the left and right limit distances, minimizing blind spots and making it suitable for complex applications such as low headroom and confined spaces.
Low maintenance costs and outstanding maintenance-free features.
Multiple components are designed to be "maintenance-free":
The high-precision hardened gear reducer is factory-filled with high-quality lubricant, requiring no oil changes throughout its lifespan.
Maintenance-free wire rope and self-lubricating rope guides reduce the frequency of replacement of wearing parts.
The brake's self-adjusting brake clearance eliminates the need for manual maintenance, further reducing maintenance time and costs. Highly intelligent, enabling more precise and efficient control.
Variable frequency speed regulation: The hoist and operating mechanisms integrate variable frequency technology, enabling soft start, micro-speed, inching, and zero-speed hovering. This ensures smooth lifting and braking of heavy objects, reduces swaying, and provides more precise positioning, improving work efficiency by over 20%.
Intelligent monitoring: Some products are equipped with safety monitors and support cloud platform connectivity, monitoring "remaining safe operating cycle, cumulative overload counts, and motor/brake pad status," enabling proactive identification of maintenance needs and enabling remote operation and maintenance.
Wide application compatibility and maximum flexibility
Flexible mounting options: The hoist can be mounted independently on an I-beam or used with electric or manual single-girder, double-girder, and gantry cranes.
Comprehensive application coverage: The hoist is suitable for use in various scenarios, from workshops, warehouses, and power plants to petrochemical, mining, and construction sites, even supporting explosion-proof and dust-proof environments (explosion-proof models).
Low replacement cost: Some products can directly replace traditional CD/MD hoists, eliminating the need for major equipment modifications and saving upgrade costs.
