Hopfällbart ankare för grapnel

At first glance, the Folding Grapnel Anchor distinguishes itself through its articulation mechanism, which allows the four-pronged flukes to fold neatly against the shank. This innovation reduces storage footprint and simplifies handling on congested job sites. Unlike a conventional Grapnel Anchor, which remains rigid at all times, the folding variant accommodates tight spaces and aids in swift deployment.

Key Differences Between Folding and Traditional Grapnel Anchors

A conventional Grapnel Anchor features fixed arms that demand ample clearance for transport and use. In contrast, the Folding Grapnel Anchor leverages a precision-engineered hinge joint constructed from hardened alloy steel, ensuring each arm locks securely under load. This joint undergoes rigorous fatigue testing to verify that repetitive opening and closing will not induce material weakening. Such dynamic examination surpasses static strength tests often applied to stationary anchors.

Materials and Construction Quality

Both anchor types are forged from high-tensile carbon steel, then subjected to a multi-stage heat treatment process yielding a Brinell hardness rating of 260–300 HB. Following forging, components receive an epoxy‑zinc dual-layer coating that exceeds 1,000 hours in neutral salt spray evaluation. This level of corrosion resistance is vital for coastal construction or marine rigging tasks. Furthermore, every unit is inspected for dimensional accuracy using laser-scanning calipers, a practice typically reserved for aerospace components rather than commonplace form accessories.

Applications and Performance Analysis

In concrete formwork, grapnel anchors serve to secure bulkheads and liners against the hydrostatic pressure of freshly poured slurry. Field trials exhibit that folding models deliver comparable pull‑out resistance—exceeding 12 kN on average—to their non‑folding counterparts while cutting transport volume by 40 percent. During a case study at a mid‑rise construction site, crews reported a 20 percent reduction in setup time, attributing gains to the anchor’s compactness and simpler tethering. This operational efficiency translates directly to lower labor costs and tighter project timelines.

Integration with the X‑Flat Tie System

The X‑Flat Tie complements our anchor range by offering a low-profile, flat-bar tension member designed for one‑and‑two‑sided formwork. Its serrated gripping surface couples with anchor shanks through a quick‑lock clevis, permitting fine‑tuned spacing adjustments without repositioning the main anchor. Available in mild steel and stainless variants, X‑Flat Ties cater to diverse projects—from high‑rise cores to precast yard installations—ensuring that each assembly maintains uniform load distribution and minimal deflection under pressure.

Kvalitetssäkring och certifieringar

Every Folding Grapnel Anchor and X‑Flat Tie undergoes batch sampling that includes tensile, bend, and impact testing, in alignment with EN 10204 inspection standards. Certificates of conformity accompany shipments, affirming compliance with ISO 9001:2015 quality management protocols. Beyond these benchmarks, an independent laboratory conducts random salt spray and hardness assessments, ensuring that material integrity and protective finishes meet or exceed industry norms.
