The Cast Iron Scaffold Hoist Pulley guides rope in temporary material-lifting setups. Its cast iron sheave turns within a painted steel frame, while the selected top connection attaches the block to a suitable support.
Product: Cast Iron Scaffold Hoist Pulley
Reference Specification: 5 in nominal size, 500 kg safe working load and 24 mm rope diameter. TOPONE will confirm these values against the approved product drawing before quotation.
Construction: Cast iron sheave with a steel frame and painted surface. The reference image shows hook and eye connection styles; specify the required style when ordering.
Applications: Guiding rope in suitable scaffold-mounted material lifting arrangements on construction and maintenance sites. Check the support structure, attachment and complete lifting system before use. This pulley is for materials, not personnel lifting.
Customization: TOPONE accepts requests for connection style, size, finish and rope compatibility. The approved design determines the final rated capacity.
Nominal Size | Reference SWL | Reference Rope Diameter |
5 in | 500 kg | 24 mm |
The table reproduces the reference product’s published values. Confirm the sheave dimensions, rope groove, connection style and load rating for the TOPONE version before publishing a final specification.
For a custom configuration, provide the intended load, rope type and diameter, attachment requirements and operating conditions.
Name: Cast Iron Scaffold Hoist Pulley
MOQ: 1 piece
Package: Carton + Steel Pallet
Manufacturing Standards: Manufacture the pulley to the approved TOPONE drawing and material specification. ASME B30.26 may provide a relevant rigging-block reference where its scope and the destination market apply. Claim conformity only after checking the completed product against the applicable requirements.
Testing Standards: Verify the sheave and groove dimensions, frame, attachment, axle, pin retention, sheave rotation and surface condition. Confirm the rated load through the approved test plan and retain the results with the product identification. Issue a test certificate only for units covered by the corresponding records.
Application Standards: Select the pulley, rope, attachment hardware and supporting structure as one lifting system. Use the marked rating for the supplied connection style and account for the forces at the block when the rope changes direction. Follow the applicable construction-site and lifting-equipment rules at the place of use.
Maintenance Standards: Inspect the frame, hook or eye, axle, pin and sheave before use. Remove the pulley from service if you find cracks, deformation, excessive wear, damaged pin retention or restricted rotation. Follow the supplied lubrication instructions. Where the system uses steel wire rope on cranes or hoists, ISO 4309:2017 provides guidance on rope inspection and discard.
