Thread Lifting Loop, Lifting Clutch System
Product Description
Thread Lifting Loop, Lifting Clutch System
- Dawson Group Ltd. - China Manufacturer, Supplier, Factory
Thread lifting loops are to be used as lifting device for the lifting anchors(Bar Anchors,Waved Anchors and Lifting Sockets) They are the most economic lifting loop and are suitable for most applications, particularly site operations. They are not suitable for turning or pitching.
Thread lifting loops can be applied with the threaded anchor with appropriate thread Rd or metric. Identification label shows the size of thread and maximum working load.
Lifting loops with changed wire length on request.
Materials:
●1 Loop: Galvanized steel wire rope
●2 Label Identification: plastic or steel
●3 Threaded socket: steel

1.Handing and use
● Thread Lifting Loops must be completely screwed in to the lifting anchor threaded sockets. If necessary, dirty threads in the lifting anchor must be cleaned.
● Thread Lifting Loop should only be attached to the unit after the concrete strength has reached 15N/m㎡.In some cases it may be economic and practical to leave the loops with the unit until final installation.
● Check that the radius of the hook is at least the diameter of the rope:
● Not suitable for turning or pitching:
● Maximum permissible lifting angle of the loops:
The lifting shall be planned in such a way so that the lifting angel β˂45°. At the larger angel, the Swivel Eye, lifting Loop with Pressure Plate or Lifting Loop“ Goliath” should e used.
2. Condition of Thread Lifting Loops
The condition of Thread lifting loops should be checked regularly. They can not be used in one of the
following faults be detected:
● 4 ruptures of wire at the distance the length of which is equal to three diameters of wire.
● 6 ruptures of wire at the distance the length of which is equal to six diameters of wire.
● 16 ruptures of wire at the distance the length of which is equal to thirty diameters of wire.
● Braiding rupture, deformation caused by pressure.
● Bended parts or swells at the bends.
● Thread damage at the wire chuck.
● Obvious wear, corrosive damage and other visible defects.
