DIN1478 Turnbuckle is a professional rigging produced in accordance with the German industrial standard DIN 1478. Common types include eye & eye, hook & hook, eye & hook, etc. Its main body is usually made of seamless cold-drawn steel pipe, mostly made of L235 or L355 steel (corresponding to China's Q235, Q345 steel), and there are also products made of 304, 316 and other stainless steel materials. There are left-handed and right-handed threads at both ends. By rotating the adjustment body in the middle, the distance between the connection points at both ends can be accurately changed to adjust the tension of ropes, steel cables, etc. Surface treatment generally includes galvanizing, hot-dip galvanizing, etc. to enhance its corrosion resistance and ensure stable use in different environments.

Precise adjustment: The unique left-right thread design allows the operator to accurately and efficiently adjust the distance between the two ends by rotating the adjustment body, achieving fine adjustment of the tension and meeting the strict requirements of tension in different scenarios.
Sturdy and durable: Made of high-quality steel, it has good strength and toughness, can withstand large tensile forces, is not easy to deform or break, and can maintain long-term stable operation even under frequent use, vibration and harsh environments.
Strong corrosion resistance: After surface treatment processes such as galvanizing and hot-dip galvanizing, the corrosion resistance of the product is effectively improved, and it is suitable for corrosive environments such as humidity, acid and alkali.
Easy installation: The overall structural design is reasonable, and the threads on both ends can be easily connected with various matching connectors. The installation process does not require complex tools and professional skills, which greatly saves installation time and labor costs.
Construction: In construction, it is used to adjust the support components of the scaffolding to enhance the overall stability; adjust the tension of the steel cables and pull rods in the building structure to ensure the safety and stability of the building structure.
Ship industry: adjust the tension of the ship's mooring ropes to ensure the safety of the ship when docked; fix the cargo in the cabin to prevent the cargo from shifting during navigation.
Industrial production: used in factories to fix heavy machinery and equipment to prevent it from shifting during operation; adjust the belt or chain tension of the conveyor to ensure the stable operation of the production line.
Agricultural scenarios: used to fix agricultural equipment, adjust the tension of agricultural fence wire, etc.
Q1: How to choose the right specification?
Choose according to the maximum load of the actual operation. For example, if you are lifting a 10-ton load, you need to choose a shackle specification with a working load limit greater than 10 tons. At the same time, refer to the dimensions in the product parameters to ensure that it is compatible with the connected ropes, chains, etc. .
Q3: What is the operating temperature range?
The shackle is certified for use in an environment of - 40°C (-40°F) to 204°C (400°F). Exceeding this temperature range may affect the material performance and connection safety .
Q3: What precautions are there for installation and removal?
During installation, be sure to tighten the threaded pin in place to prevent loosening; during removal, avoid violent operation to damage the thread. Before and during use, regularly check for thread wear and cracks on the body.
Q3: Can relevant certifications be provided?
Some manufacturers can provide certification certificates for specified standards such as ABS, DNV, Lloyds, etc., which need to be requested when placing an order, and may incur additional costs .
