Big Connector SLR G80 32mm 31.5T Heavy Spring Retainer Lifting Connector

When the lift demands reliability, traceability, and speed in tight spaces, the Big Connector SLR G80 delivers. Built by HES NZ LTD, this purpose-built lifting connector is designed for medium to heavy lifts in space-constrained environments, offering fast engagements and a secure load-pin retention that stays locked under strain.

Key benefits that matter on site

• 32 mm body diameter provides a compact yet capable profile for overhead and tight-point rigging.
• 31.5 t working load limit (WLL) with Grade 80 steel delivers durable performance under continuous use and shock loading.
• Heavy spring retainer ensures the load pin remains engaged during dynamic loads, reducing accidental disengagement and downtime.
• Bright safety-yellow coating enhances visibility on cluttered worksites and adds basic corrosion protection in typical shop environments.
• Fast-engage design minimizes setup time between lifts, helping crews move efficiently through repetitive rigging tasks.
• Traceable manufacturing data: clear markings for batch, size, and rating support audits and third-party inspections.
• Compliance: engineered to EN 818.4, EN 1677-1, AS 3776, NZ Department of Labour code of practice, and LEENZ guidelines — for peace of mind in regulated operations.
• Vendor-backed availability: shipped directly from the supplier with support for multi-unit orders, useful for larger rigs or maintenance programs.

Ideal use cases

This connector is designed for rigging teams, crane operators, and maintenance crews who work in spaces where traditional fittings struggle to fit or where quick, auditable lifts are essential. Its fast-engage action is particularly beneficial for multi-pick operations, overhead rigging points, and confined workshops where every second matters and safety records must be pristine.

Care, safety and inspection tips

Regularly inspect the pin and retainer for wear, corrosion, or debris. Verify batch/date markings before each lift and maintain a clean storage environment to protect the coating. Never exceed the 31.5 t WLL, ensure proper alignment to avoid side loading, and keep auditable records with the product identity data (Product No. SLR074HL-32F, batch date).
