Features & Advantages
Glory Rail’s hot-rolled crane sheaves offer five key advantages over traditional cast pulleys. As a professional supplier of hot-rolled crane sheaves, we design every wire rope pulley and crane pulley for maximum durability and efficiency.
High Strength: The hot-rolling forming process optimizes the internal grain structure, resulting in excellent resistance to bending and torsion.
40% Lighter Weight: Made from Q345B high-strength steel plate, it is 40% lighter than cast pulleys of the same specifications.
Superior Wear Resistance: Flame-hardened rope grooves with surface hardness HRC 40–45 and induction hardening depth >2mm maintain performance long-term.
Extended Rope Groove Life: The smooth, wear-resistant surface of the rope groove extends the pulley’s service life by 1 to 2 times.
Hot-Rolling Production Process
Every rolled crane sheave wheel produced by Glory Rail undergoes a rigorous 7-step hot-rolling forming process. From CNC oxy-fuel cutting of Q345B high-strength steel plate, to billet heating and rolling—achieving near-net-shape forming—and on to annealing, welding, CNC precision machining, and comprehensive inspection, every step is subject to quality control.
1
Gas Cutting
CNC cutting technology cuts Q345B high-strength steel plate into disc-shaped blanks, resulting in minimal material waste and blanks of consistent quality that are free of deformation and burrs.
2
Billet Heating
Heating the outer diameter of the blank induces significant compressive stress on the surface, forming a martensitic hardening layer with a finer microstructure and higher hardness and toughness.
3
Roll Forming
The hot-rolling forming process involves rolling the wheel flange as a single piece before welding it; near-net-shape forming reduces energy consumption and ensures uniform surface hardness in the rope groove area.
4
Annealing & Cooling
After heating to the target temperature, the material is held at that temperature and then slowly cooled to increase ductility and toughness and refine the grain size, thereby improving its mechanical properties.
5
Welding
Optimize stress distribution to improve the fatigue life and reliability of the hub, and enhance its load-bearing capacity and impact resistance.
6
CNC Finishing
Turning and grinding meet design specifications; after flame hardening of the rope grooves, the surface hardness is HRC 40–45, and precision grinding machines ensure dimensional accuracy of the outer diameter and groove dimensions.
7
Testing & Inspection
Ultrasonic, magnetic particle, hardness, and carburization testing ensure quality; mechanical properties (yield, tensile, and impact) and metallographic testing meet forging requirements; and an induction hardening depth of >2 mm has been verified.
Are you looking for crane pulleys with high load-bearing capacity and guaranteed quality? As a manufacturer of hot-rolled crane pulleys, Glory Rail offers custom-sized hot-rolled pulleys at factory-direct prices.
Typical Applications
Glory Rail’s hot-rolled crane sheaves are widely used in foundry overhead cranes, truck cranes, and tower cranes. These wire rope sheaves for cranes operate reliably in harsh environments—from high-temperature foundry shops to outdoor construction sites—providing stable power transmission for heavy-duty lifting equipment.
Foundry Overhead Cranes
Surface hardness of HRC 40–45 enhances contact friction stress and provides excellent wear resistance in high-temperature casting environments.
Truck Crane Hook Blocks
Hot-rolled Q235B/Q355B steel, designed to prevent casting defects, with precision rope grooves that perfectly accommodate steel wire ropes.
Tower Crane Hook Blocks
The combination of fixed and moving pulleys reduces vibration and noise, ensuring smooth operation and self-lubrication.
When the pulley diameter exceeds 600 mm, large-diameter rolled crane sheaves outperform cast alternatives and offer superior fatigue resistance. This makes our products an ideal choice for industries requiring OEM/ODM crane pulley solutions, such as steel mill production lines, shipbuilding, wind power, and port machinery.
