What should be paid attention to in the daily operation and maintenance of straight seam steel pipe cantilever cranes?
1. The steel wire rope should be replaced when 10% of its strands are broken.
2. Regularly check whether the lifting brake of the crane hook is functioning properly and is sensitive.
3. Regularly check the limit switches at the front and rear of the trolley, and ensure that the limit switch for the maximum lifting height of the hook is functioning properly and is sensitive.
4. Lubrication points for straight seam steel pipe gears, sprockets, chains, ropes, etc. should be regularly lubricated.
5. When operating the cantilever crane (32T double-beam crane - LH electric double-beam bridge crane), close cooperation with the rigging personnel is required, and the rigging personnel's instructions must be followed.
6. When lifting strip steel coils with straight seam steel pipes, it is necessary to lift and lower gently, ensuring stable, precise, and light operation.
7. The lifting hook should be fully loaded with coils.
8. When lifting straight seam steel pipes with a crane, it is prohibited to pull the steel wire rope diagonally to prevent it from slipping out of the groove.
9. During operation, attention should be paid to safety to ensure the safety of personnel and equipment.
The straight seam steel pipe uncoiler is a device used to uncoil steel coils. The main types of straight seam steel pipes include rotary table type, box type, single-cylinder type, double-cylinder type, and double-cone type. The rotary table type uncoiler has a very simple structure. It is a rotary table placed flat on the ground with a shaft in the middle. When uncoiling, the steel coil is placed flat on the rotary table, and the ends of the coil are directly fed into the forming unit. The straight seam steel pipe rotates freely and uncoils as the forming and welding unit starts, without any other preparatory processes or equipment in between.

The straight seam steel pipe uncoiler has a simple structure, does not require large investment and equipment, and is easy to operate. Moreover, the slight scattering of the straight seam steel pipe strip coil does not affect the uncoiling process. The disadvantage is that it is relatively outdated, requires heavy manual labor, and the steel strip may twist, causing the edges of the steel strip to be easily scratched. This type of straight seam steel pipe uncoiler can be used as a temporary short-term uncoiling device.
