The Half Side Block guides rope through lifting and pulling systems. Its partially open side design and removable pin make rope installation and rigging changes more convenient, while the single sheave keeps the assembly compact.
The Half Side Block combines a single grooved sheave, a half-side frame and a top attachment point for industrial rigging. Its accessible side and removable pin help operators install or change the rope during setup. Compared with a fully enclosed frame, the design also provides easier access to the sheave for inspection.
The reference configuration describes steel side components, a painted finish, a flame-hardened cast sheave and a bronze bushing. Together, these features aim to reduce wear at the rope contact surface and support smooth sheave rotation. Confirm the materials, finish and bearing arrangement against the final TOPONE product drawing before specifying them to customers.
This block may suit suitable crane, winch, construction and material-handling arrangements. Select it according to the verified block rating, rope diameter, attachment method and forces acting on the complete rigging system.

Name: Half Side Block
MOQ: 1 piece
Package: Carton + Steel Pallet
Rigging Hardware: ASME B30.26 is a relevant reference for rigging blocks, including their use, inspection and maintenance. Confirm compliance against the applicable edition and TOPONE’s product records before making a conformity claim.
Rope Inspection: ISO 4309:2017 provides guidance on the care, maintenance, inspection and discard of steel wire ropes used on cranes, winches and hoists. Match the rope diameter and type to the verified sheave specification.
Product Verification: Inspect the attachment point, side components, pin retention, sheave rotation and rope groove against the approved drawing. State rated capacity, proof-load results, material grades and certifications only when supporting TOPONE records are available.
Maintenance: Check the block before use and remove it from service if you find cracks, deformation, excessive wear, a loose pin or restricted sheave movement. Lubricate moving parts according to the supplied instructions.
