Crane Sprocket
What is Crane Sprocket
Crane sprocket is a mechanical component in the crane drive system, particularly in tracked cranes, such as crawler cranes. The drive wheel is a gear that meshes with the track chain, transferring rotational power from the drive motor to the tracks, and enabling crane movement.
Crawler Crane Sprockets Parameters
Name: Drive wheel or crane sprocket
Applicable Models: Suitable for all crawler crane models
Material Options: 35SiMn for enhanced strength and durability.
High Surface Hardening: Single-point induction hardening (HRC>50) for enhanced wear resistance. Tempering prevents fracture, and a minimized design reduces stress concentration, prolonging service life.
Custom Processing: Yes, custom processing is available
Why choose us?
For the crane sprocket, VM® is able to provide more than 20 models such as Kobelco, liebherr, hitachi, sumitomo, Manitowoc, IHI, Link Belt, Sharyo Nippon, XCMG, SANY, Zoomlion, etc.
High-strength material
Cast with 35SiMn, and after strict chemical composition testing, quality crane sprocket has extremely high pressure resistance and wear resistance, ensuring that it is not easy to be damaged under long-term high-load operation.
Precision manufacturing process
Advanced finishing technology combined with strict quality control ensures precise size and tooth shape for the drive wheel. This accuracy helps minimize wear, improving performance and significantly extending the service life of the component.
Advanced sealing technology
Sealing technology in the crawler crane sprocket is essential for efficient drive system operation and extended service life. We use imported O-ring seals and pure copper sleeve seals. Our high-quality crane sprocket has efficient sealing performance, working stably under high pressure to reduce oil leakage and damage risks.

How to install the crane sprocket
01
Prepare the Crane
Before starting the installation, ensure the crane is turned off with the engine not running. Wear appropriate safety gear, such as gloves and goggles. If necessary, lift the crane using hydraulic jacks or a hoist to relieve tension from the tracks and sprocket. Securely block the tracks to prevent any unintended movement during the installation process.
02
Remove the Old Crawler Crane Sprocket
Use a wrench or socket set to loosen and remove bolts or nuts securing the old crane drive wheel to the shaft. Once the fasteners are removed, carefully pull the crane sprocket off the shaft. You may need to use a puller if the sprocket is stuck due to rust or wear.
03
Clean the Shaft and Mounting Area
Before installing the new crane sprocket, inspect the shaft for any damage, wear, or rust. Clean the surface thoroughly using a wire brush or cloth. Apply a thin layer of grease or lubricant to the shaft and mounting area to ensure smooth installation and reduce friction.
04
Install the New Sprocket
Carefully align the new crawler crane sprocket with the mounting holes on the shaft. Make sure the teeth of the sprocket are oriented correctly with the direction of the track movement.Gently slide the sprocket onto the shaft, ensuring it fits properly without forcing it into place.
05
Secure the Sprocket
Use the appropriate bolts or nuts to secure the crane drive wheel to the shaft. Tighten the bolts in a criss-cross pattern to ensure even pressure distribution.Use a torque wrench to tighten the bolts to the specified torque settings as per the crane manufacturer’s manual. This is important to prevent any slack or over-tightening that could damage the sprocket or shaft.
06
Inspect and Test the Installation
Ensure the crane sprocket is correctly aligned with the tracks and that the teeth mesh properly with the track system.Start the crane and slowly test its movement, paying attention to any unusual noises or vibrations. Check for smooth operation and proper tension in the tracks.
