Chain-type Simple Platform

Updated: 2026-07-21

Overview

Chain-type simple platforms are prefabricated access systems consisting of interlocking metal platforms connected by chain mechanisms. Originally developed in the 1980s for shipbuilding applications, their modular nature allows rapid deployment in confined spaces where traditional scaffolding is impractical. Modern versions incorporate lightweight aluminum alloys or corrosion-resistant steel, with standardized widths (600-1000mm) and lengths (1.5-3m per module). They dominate 35% of the temporary access equipment market in Europe and Asia due to their reusability and compact storage.

Structure and Working Principle

The platform's core components include perforated deck panels, chain-link suspension systems, and adjustable leg assemblies. The chain mechanism permits ±15° angle adjustments for uneven surfaces while maintaining structural integrity through triangulated load distribution. Load-bearing capacity derives from the material thickness (1.5-3mm for aluminum, 2-4mm for steel) and ribbed underside designs. Most systems use twist-lock connectors that engage automatically when platforms are stacked, reducing assembly time by 60% compared to bolt-together systems.

Key Features

1. Portability: Aluminum units weigh 12-18kg/m² versus 25-40kg/m² for steel, enabling manual handling by two workers. Foldable versions reduce storage volume by 75%. 2. Safety: Standard features include serrated tread surfaces (0.8mm+ profile depth), toe boards, and guardrail compatibility. Leading models meet EN 131-7:2013 for mobile access equipment with 1.5x safety factors on stated loads.

Application Areas

Construction: Facade work and interior finishing where frequent repositioning is needed. The automotive industry utilizes them for assembly line modifications. Industrial Maintenance: Preferred for refinery turnarounds due to spark-resistant aluminum options. Maritime applications benefit from saltwater-resistant galvanized variants with 3000+ hour salt spray ratings.

Maintenance and Precautions

Monthly inspections should check for chain link wear (>10% elongation requires replacement) and deck surface integrity. Steel platforms need annual rust treatment if paint is compromised. Critical precautions include: Never exceed the manufacturer's stacking limit (typically 3-4 tiers); use outriggers for heights >2m; and ensure all locking indicators show engaged positions before use. Wind speeds above 28mph (12.5m/s) mandate work cessation.

B2B Procurement Guide

For bulk purchases (50+ units), request mill certificates for material verification. Key commercial terms should include: 10-year structural warranty, replacement part availability guarantee, and customized branding options. Leading manufacturers include Layher (Germany), Safway (USA), and RMD Kwikform (UK). Asian suppliers typically offer 15-20% lower pricing but may lack full certification documentation. Always verify third-party testing reports for load claims.
