The double-girder design provides exceptional load-bearing capacity and structural stability, distributing weight evenly across the tracks to avoid deformation during high-tonnage lifting. The reinforced main beam and trolley frame are made of high-strength steel, ensuring reliable operation under long-term high-intensity workloads.
Equipped with a stepless inverter speed control system, the hoist achieves smooth acceleration and deceleration, minimizing load swing even when lifting large-tonnage objects. The dual-trolley model (available for 15+15t, 20+20t) enables synchronous or independent lifting, adapting to irregularly shaped or extra-heavy loads.
With a standard protection class of IP55 and an optional IP65 upgrade, the hoist resists dust, moisture, and even short-term water splashes, making it suitable for both indoor workshops and outdoor yards. The corrosion-resistant coating on the surface extends service life in humid or corrosive environments.
The sealed reducer adopts lifelong lubrication technology, eliminating the need for frequent oil changes. The self-adjusting brake automatically compensates for wear, reducing maintenance frequency and costs. High-wear components such as the large-diameter steel wire rope drum and high-strength hooks have an extended service life, lowering replacement costs.
In addition to basic safety devices, the hoist is equipped with an anti-collision device to prevent collisions between trolleys or with crane ends. The overload protection system features dual sensors for double insurance, and the emergency stop system cuts off power instantly in emergencies, ensuring the safety of operators and equipment.
Ideal for lifting large mechanical components, such as engine blocks, machine tool beds, and steel structures, in industries like construction machinery, shipbuilding, and aerospace manufacturing.
Suitable for handling bulk materials (coal, ore, steel ingots) and heavy equipment (generators, transformers) in power plants, steel mills, and smelting workshops.
Used for loading and unloading large cargo, containers, and pipe fittings in outdoor yards, ports, and railway freight stations, adapting to complex outdoor working environments.
Applicable to high-bay warehouses and heavy equipment assembly lines, such as automobile manufacturing plants (lifting car bodies, engines) and logistics centers (handling large containers and machinery).
Ensure the double-girder crane track is accurately calibrated (levelness error ≤2mm/m) and the foundation bearing capacity meets the hoist’s requirements.
Use professional lifting equipment for installation; strictly follow the manual to align the trolley with the track and secure all fasteners to avoid loosening during operation.
Test the hoist’s synchronization (especially for dual-trolley models) and safety device functionality after installation; only put it into use after passing the load test.
Inspect the steel wire rope and hook monthly for wear, corrosion, or deformation; replace if the wear exceeds 10% of the diameter or if there are broken strands.
Clean the motor cooling system and electrical control box quarterly to ensure effective heat dissipation and prevent electrical failures.
Check the trolley’s running wheels and track contact surface semi-annually; adjust or replace wheels if there is uneven wear.
Conduct a comprehensive safety inspection annually, including load testing, brake performance testing, and electrical system calibration.
