Crane Pulley Block
Factory-Direct High-Capacity Sheave Assemblies For Safe,Efficient Lifting
With extensive experience in manufacturing crane components,we are a crane source factory providing factory-direct pulley block solutions.
Our Crane Pulley Blocks combine precision machining,hardened sheaves,and balanced assemblies to deliver reliable performance across overhead cranes,
gantry cranes,hoists,and heavy lifting systems worldwide.
The Crane Pulley Block reduces rope tension,improves reeving efficiency,and protects wire rope life in demanding industrial conditions.
Available as single-,double-,triple-sheave and multi-sheave configurations,each pulley block is designed to match customer specifications and OEM requirements for maritime,steel,
construction,and logistics applications.
Product Introduction
Our pulley blocks are manufactured to meet strict pulley block specifications and industry standards.Sheaves are forged or cast from high-strength alloy,
heat-treated for wear resistance,and CNC-machined for precise rope groove geometry.Frames are reinforced and balanced to minimize vibration and ensure smooth rope tracking.
We offer customized OEM designs,wholesale supply options,and export-ready packaging for global distributors and dealers.
Key Features
High Load Capacity&Reliable Bearing Support
Engineered frames and heavy-duty bearings support single and multi-part reeving arrangements for increased lifting capacity.
Precision Groove Profiling
CNC-machined grooves reduce rope fatigue and improve rope life for frequent start-stop operations.
Multiple Configurations&Mounting Styles
Hooked blocks,fixed blocks,traveling blocks,flange-mounted and custom multi-sheave assemblies to suit various crane applications.
Durable Materials&Surface Treatments
Options include heat-treated alloy steel,ductile iron,hot-dip galvanizing,and marine-grade coatings for corrosive environments.
Balanced Sheave&Low Vibration
Dynamic balancing reduces vibration and noise,improving safety and extending bearing service life.
Factory-Direct Customization&Supply Chain Support
We provide detailed pulley block specifications,custom OEM solutions,and support for suppliers,exporters,and distributors.
