Description

Flagcrane has developed series of crane hook block in accordance with the latest requirements and techniques FEM 1001 and DIN STANDARD 15020.

1. The crane hook block is generally made of DG20 steel and DG34GrMo alloy steel, which is forged, pressed, annealed and then machined. It has the characteristics of high strength, good plasticity and toughness.
2. The crane hook block is generally made of A3, 20# or 16Mn steel plate, the thickness is not less than 20mm, without sudden break, and the reliability is high.
3. Flaps of hook block are generally used in places with large tonnage in high temperature environments.
4. . All hooks will be equipped with safety latch to prevent the load from unhooking.
5. Ratio of pulley diameter and wire rope diameter is greater than 20 to ensure service life of rope.
6. A protective pad is set at the hook mouth to ensure that the hook mouth will not be damaged by the friction of the spreader and prolong its service life. The protective pad can be replaced when it is damaged.

The single hook is simple to manufacture and easy to use, but the force is not good, and it is mostly used in the workplace with a lifting capacity of less than 80 tons.

When the lifting capacity is large, double hooks with symmetrical forces are often used.

Laminated hooks are riveted from several cut and formed steel plates. When individual plates have cracks, the entire hook will not be damaged. The safety is good, but the self-weight is large. Most of them are used for large lifting capacity or lifting molten steel ladle on the crane. The hook is often impacted during the operation and must be made of high-quality carbon steel with good toughness.ne system to operate quickly, stably and reliably.

Advantages

1. Enhanced Safety

• ‌Anti-Fall Design‌: Features like safety latches, limit slots, and anti-drop guards prevent lifting straps or heavy loads from slipping, especially in high-altitude or windy conditions.
• ‌Overload Protection‌: Built-in sensors monitor weight in real-time. If overloaded, the system triggers an alarm and stops operations to avoid accidents.
• ‌Durable Materials‌: Made with wear-resistant materials (e.g., manganese steel) and impact-absorbing pads to withstand harsh conditions and extend lifespan.

2. High Efficiency

• ‌‌Precision Control‌: Supports wireless remote control and smart systems (like PLC) for accurate lifting of containers, steel beams, and more.
• ‌Heavy-Duty Capacity‌: Available in single/double hooks or closed designs, with lifting capacities up to 250 tons.
• ‌360° Rotation‌: Electric rotating hooks adjust load angles effortlessly, ideal for ports and factories.

3. Versatility

• ‌Multiple Designs‌: Forged hooks (high strength) and modular hooks adapt to different loads and industries.
• ‌Tough Environments‌: Waterproof and corrosion-resistant options work underwater or in extreme heat (e.g., steel mills, ports).
• ‌Lightweight Build‌: Reduces crane energy use and operating costs.

4. Easy Maintenance

• ‌Easy-to-Replace Parts‌: Modular components (e.g., guards, springs) minimize downtime.
• ‌Long Lifespan‌: With proper care, hooks last 8-10 years and require minimal upkeep.

Features

• Special heat-treated forged steel hook block with latch.
• Heavy duty worm gear reducer.
• Tapered roller bearing with grease fittings.
• Forged steel pulleys with hardened rope grooves.
• Easy maintenance.
• Direct spur gear transmission.
