Materials of Tower Crane Pulley
Steel
Durable and strong, suitable for heavy-duty cranes.
Aluminum Alloy
Lightweight, ideal for medium to light-duty cranes.
Composite Materials
Used in environments that require lightweight, corrosion-resistant pulleys.
Types of Tower Crane Pulley
Fixed Pulleys
These are bolted onto the crane's frame and don't move. Their main job is to change the direction of the rope—handy for pulling from a different angle, like downward instead of upward.
Movable Pulleys
These are hooked to the load and shift as it moves. They're the ones that start giving you that force-reducing boost by sharing the weight across multiple rope strands.
Compound Pulleys
This is when you mix fixed and movable pulleys together for a double whammy—changing direction and cutting down the effort needed. You'll see these in cranes tackling really hefty loads, like the ones used to build skyscrapers.
Choose the Right Pulley for Your Tower Crane
Load requirements
If your crane needs to lift very heavy materials, steel pulleys are more suitable due to their excellent tensile strength.
Usage frequency
Steel pulleys offer better long-term durability for continuous or high-intensity use. Cast pulleys are suitable for occasional or light to moderate operations.
Project budget
If budget constraints are the main consideration, casting pulleys is an economical and efficient solution. However, since steel pulleys need to be replaced less frequently, the total life cycle cost can be reduced.
Environmental conditions
In Marine or high-humidity environments, please choose materials with corrosion resistance or ensure that the steel pulleys are properly rust-proof treated.
Safety margin
In high-risk environments such as skyscraper construction, even if the initial cost is high, stronger and more reliable components should always be chosen.
Manufacturer's reputation
Whether you choose steel or cast pulleys, you should cooperate with a reliable pulley tower crane manufacturer, who can provide quality control, material certification and after-sales support.
Features of Tower Crane Supporting Bracket
Super bearing capacity to ensure the safety of high-altitude work
The support frame has excellent bearing capacity and anti-deformation performance. We use Q460D high-strength low-alloy steel (in line with GB/T 1591 standard), and eliminate internal stress through multi-pass hot rolling process to ensure that the support frame has no plastic deformation under extreme loads.
Modular assembly design to improve construction efficiency
In view of the pain points of high-altitude installation efficiency, the support frame adopts a modular quick-assembly structure, and all components are pre-installed with positioning pins and high-strength bolt holes, and the on-site installation time is shortened by 70% compared with the traditional welded support frame.
Anti-fatigue design to prolong service life
The key nodes of the support frame adopt arc transition structure and local thickening process to avoid fatigue cracks caused by stress concentration. At the same time, the surface is hot-dip galvanized (zinc layer thickness ≥ 85μm), and it has passed the 2000-hour salt spray test without corrosion.
Intelligent monitoring interface (optional) to achieve preventive maintenance
In order to meet the needs of smart construction sites, the support frame can integrate strain sensors and wireless transmission modules to monitor the stress distribution and deformation of the structure in real time.
Applications of Lifting Brackets in Construction
Residential Construction
Painters, roofers, and maintenance crews often use small fixed brackets to hoist paint cans, tools, or light materials.
01
Commercial Projects
On high-rise buildings and office complexes, adjustable or heavy-duty brackets can be used to lift glazing panels, ductwork, or interior materials.
02
Industrial Sites
Power plants, refineries, shipyards often use heavy-duty brackets for moving large components like pipes, valves, or fabricated modules.
03
Infrastructure Works
Bridges, tunnels, highways projects often involve specialized formwork and heavy materials. Specialty brackets help lift and position these more easily.
04
Case Example
A contractor building a large overpass used heavy-duty lifting brackets with built-in pulleys to hoist formwork panels directly from the ground, saving crane time and costs. The system also improved worker safety by minimizing manual handling at height.
05
