Solid as steel, accurate as lock-carbon steel lock head casting for construction machinery, escorting heavy-duty projects

Hard core guarding, rock-solid-carbon steel lock head castings for construction machinery, defining new engineering safety standards

 On the high-intensity and high-load construction site, every detail is related to success or failure, and every connection carries safety.

As one of the key stress components, the lock head casting of construction machinery not only needs to bear repeated impact and heavy pressure, but also must remain stable and reliable in extreme environment.

To this end, we introduce high-quality carbon steel construction machinery lock head castings-hard core of materials, casting the peace of mind of the project. 

Why choose carbon steel? 

High strength and toughness: high quality carbon structural steel (such as Q235, 45# steel, etc.) is selected, and after precision casting and heat treatment, the lock head is ensured not to deform and crack under high load.

Excellent wear resistance: the surface is quenched and tempered or high-frequency quenched, which greatly improves the wear resistance, prolongs the service life and reduces the replacement frequency.

Excellent welding and machining performance:

convenient for subsequent assembly and maintenance, and suitable for various construction machinery interface standards. 

Strong weather resistance: even in the damp, dust and severe temperature difference environment, it still maintains structural integrity and functional stability.

Wide range of application scenarios

Our carbon steel lock head castings are widely used in: 

Standard section connection locking of tower crane

Locking mechanism of boom of concrete pump truck Safety interlock device of engineering elevator

Quick locking of formwork support system

Key locking parts of other heavy construction machinery and equipment 

Quality commitment

Each casting passes: 

 Material spectral analysis

Ultrasonic/magnetic particle flaw detection Re-inspection of dimensional accuracy CMM Load simulation test

Controlling the quality from the source is only to ensure the peace of mind of "zero defect" in your hands. 

Choosing our carbon steel lock head castings for construction machinery means choosing: 

Higher security redundancy 

Longer service period 

Lower comprehensive cost 

More reliable engineering partner
