custom ingot tongs
Ingot tongs from OLICRANEPARTS are engineered for the high-stakes handling of massive steel, aluminum, and copper blocks in modern smelters and foundries. As a specialized category of our crane lifting tongs and clamps, these tools are built from high-strength alloy steel to endure the brutal thermal cycles of furnace loading and unloading.

Vertical ingot tongs
These vertical ingot tongs feature a purely mechanical auto-locking mechanism. The design is simple and reliable: it requires no external power and operates solely by the weight of the ingot. A built-in gravity-based positioning device coordinates the jaws, allowing them to open and close automatically during the lifting cycle. This setup ensures flexible, safe, and unmanned handling in high-intensity foundry environments.

Silicon ingot clamp
Our silicon ingot clamps are precision lifting tools designed to handle fragile crystal ingots without surface damage. As a specialized part of our crane lifting tongs and clamps lineup, these devices are widely used in the new energy, semiconductor, and solar cell industries.
We currently provide G5, G6, G7, and G8 standard models, all engineered for simple, secure, and non-marring operation. For unique production lines, OLICRANEPARTS also offers custom-developed clamping solutions tailored to your specific ingot dimensions and handling requirements.
