Product parameters:
Name: O-type main lock
Weight: 168g
Material: alloy steel, hot forged aluminum magnesium alloy
Maximum tension: 25KN
Opening tension: 8KN
Opening width: 18mm
Scope of application: mountaineering, expansion, cave exploration, electric rescue, aerial work, hoisting, engineering protection.
Unlocking instructions:
1. Screw lock (1D) is stable and reliable in harsh environments such as dust, mixed sand, ice and snow, and is suitable for the use of infrequently opening and closing lock ports.
2. Automatic locking (2D) is suitable for the use of frequently opening and closing the lock port, so as to avoid confusion and error, and forget to close the lock port, causing danger, and reduce the occurrence of wrong opening during operation.
3. The three-step locking (3D) is particularly suitable for rescue situations. Due to the complexity of the environment, the occurrence of false unlocking in the process of high-altitude action is largely prevented.
Manufacturing process:
1. Hot extrusion: hot extrusion has good plasticity, high accuracy and small surface roughness.
2. Hot forging process: the hot forging process can reduce the as cast defects of aluminum magnesium alloy and improve the mechanical properties and plasticity of aluminum magnesium alloy.
Product details:
1. Alloy steel material: alloy steel material, outer chrome plating, brighter, strong corrosion resistance, high tension, good firmness.
2. Screw thread main lock: the screw thread main lock is stable and reliable in harsh environments such as dust, sediment, ice and snow, and is suitable for the use of infrequently opening and closing the door.
3. Shape: O-shaped design, making the opening larger, connecting the safety belt and the safety belt is always on the long shaft, and the bearing pressure is better.
4. Anti slip nut: the lock nut adopts concave convex anti slip design, which is more convenient and smooth to use. The product safety is further guaranteed.

Use and maintenance of main lock:
1. The main lock should not be in contact with chemicals, and should be in contact with mud and sand as little as possible.
2. Clean the main lock in water below 40 ℃ and dry it naturally.
3. Do not make the main lock fall to the ground from a high place, otherwise the internal damage is invisible to the naked eye.
4. It should be stored in a dry and ventilated place, avoiding contact with heat sources, and should not be placed in a wet place for a long time.
5. Any external pressure on the lock port is very dangerous, which may cause damage and fracture of the lock port.
6. The main lock complies with the CE standard. The service life of the main lock is related to its service condition, and the service frequency and service environment have an impact on its service life. Generally speaking, the service life of the main lock should not exceed 5 years.
Replace the main lock when the following phenomena occur:
1. When the groove at the worn part exceeds 1/4 of the diameter of the main lock.
2. When the lock door of the main lock cannot be opened and closed normally.
3. When the turnbuckle for locking the door cannot be closed and opened normally.
4. When the main lock comes into contact with chemicals.
5. When the main lock falls to the hard ground from a high place.
6. When the main lock is strongly impacted.
