Precast concrete lifting eyes are made of high-performance alloy steel and are specially used for lifting the clutch of lifting pin anchor.It may also be called: lifting clutch, lifting clutch for precast concrete, dog bone lifting eye, precast lifting eye.
It consists of 3 parts:
It is the structure that connects the lifting pins. Made using precision casting technology.It is spherical with a tongue, flat on both sides, and has a through hole on the flat surface, where the ring connecting the handle passes through.The tongue on its spherical surface is used to push the lifting pins into the grooves in the head.The groove on the spherical surface has a larger opening to facilitate the entry of the heads of the lifting pins.
It is the structure that connects the lifting hooks and the head. The handle is made by laser cutting, and the chain is made by heat bending and welding. The handle has a large cavity, which is convenient for the hook to be placed. The tail of the handle is marked with the load group of precast concrete lifting eyes.
It is the structure that connects the head and the handle (chain). It is made by hot bending and the whole is assembled by welding. The connection between it and the handle is welding.
We can divide Precast concrete lifting eyes into two types: with chain and with handle according to one end of the link chain.
The general certification for Precast concrete lifting eyes is CE certification. The quality management standard is ISO 9001. They will undergo strict spot checks before leaving the factory. The tensile test will use a tensile force of 2 times the safety factor to complete the use level test (the overall structure cannot be deformed). The destructive test is completed using a tensile force of 5 times the safety factor.
Its use is divided into three parts: installation, lifting, and release.
1. Check the load duty of the anchor and make sure it is in the same load group as the precast concrete lifting eyes.
2. Hold the handle, or hang the handle on the hook first; move the head and insert the lifting pin anchor into the center seam.
3. Push the tongue on the ball so it closes tightly on the anchor.
1. The devices can also be rotated on the lifting anchors when pitching the devices. Noted: The tongue must be closed during this process.
2. The counterweight of the tongue ensures that the sphere remains in the correct position, even when the load is released.
3. When the system is loaded, due to the influence of friction, the precast concrete lifting eyes are almost difficult to rotate. We can apply grease on the lifting pin anchor before loading.
1. Make sure the load has been completely removed.
2. Push the tongue to rotate the ball until the lifting pin anchor exits the ball.
3. Lift the precast concrete lifting eyes off the pin anchor.
Our quality control center has advanced testing equipment that can complete: material physical and chemical properties, product tolerances, mechanical properties and anti-rust performance, etc. Our quality inspectors will strictly conduct random inspections of precast concrete lifting eyes and attach detailed test reports to each batch of orders.
Our quality inspectors strictly measure the width of the ball's center seam, the overall length of the precast lifting eyes, and other important parameters.
Before the order is shipped, we will unpack and inspect again to ensure that both quantity and quality are up to standard.
Based on the precise weight of each piece, use an electronic scale to measure the total amount, subtract the packaging weight from the total amount to get the actual weight, and then divide it by the weight of each piece to get the number of precast concrete lifting eyes.
The tensile test of Precast concrete lifting eyes will be conducted with a destructive test at 5 times the safety factor tensile force and a performance test at 2 times the tensile force.
We have a closely-knit precision casting plant, surface treatment plant and forging plant (equipped with advanced cutting machines, presses and welding machines).The entire order will be completed more smoothly under our strict management. You can contact us at any time to visit the factory and understand our production capacity before placing the order with us.
