ISC 13mm Compact Forged Rigging Pulley Block

ISC 13mm Compact Forged Rigging Pulley Block

The ISC 13mm Compact Forged Rigging Pulley Block delivers an impressive strength-to-weight ratio in a highly compact format. At approximately half the size of a standard small rigging pulley and weighing just 490 g (1 lb), it offers a minimum breaking strength of 85 kN and a working load limit of 17 kN.

Hot forged aluminium construction

The pulley plates are manufactured from hot forged aluminium. This forging process enables the compact body to achieve high strength and dynamic load-bearing capacity while maintaining reduced overall dimensions and weight.

Dedicated sheaves for working line and strop

The grey working line sheave is rated for 13 mm (1/2″) rope with a strength of 38 kN (8500 lbf). The red anchor sheave is rated for 16 mm (5/8″) topping strop with a strength of 74 kN (16650 lbf). The pulley is fitted with a spring-lock closure mechanism for secure operation.

Compact dimensions with serial traceability

The pulley features an anodised body finish in green and grey. It measures 125 mm in height and 76 mm in width, with individual serial numbering provided as standard. It is approved under CE 0120 Machinery Directive.
