The E600 double triangular manhole cover offers a 1220 × 675 mm clear opening and 150 mm frame height, engineered for areas imposing exceptionally high wheel loads such as docks, aircraft pavements, and transport yards. It is BS EN124‑2:2015 Group 5 certified, capable of withstanding 600 kN (60 tonnes) of wheel load. Constructed from high‑strength ductile iron with a durable bitumen or epoxy finish, it delivers outstanding corrosion resistance and structural integrity. Its double‑triangular, non‑rock hinged lid design provides smooth, one‑person operation while preventing cover movement under heavy traffic. Optional accessories—such as screw locking, pressure release vents, flood‑control plates, and custom badging—allow enhanced security and functionality. Third‑party BSI Kitemark certification and HA104/09 compliance guarantee regulatory adherence and consistent quality for highway installations.

Overview

Group 5 E600 access covers and frames are designed for use in areas of exceptionally high wheel loads such as docks, aircraft pavements, transport yards, and loading bays. The clear opening measures 1220 × 675 mm, with overall frame dimensions of 1310 × 790 mm and a 150 mm frame depth. Enlarged frame corners dissipate loads more effectively into the foundation, extending service life and improving reliability. Fully compliant with UK Highways Agency HA104/09 and DMRB CD534 technical regulations, it meets the strictest highway standards.

Key Features

• BS EN124‑2:2015 Group 5 Certification: Rated for continuous wheel loads of up to 600 kN (60 tonnes) per standard.

• Clear Opening & Frame Dimensions: 1220 × 675 mm clear span with a 150 mm deep frame and 1310 × 790 mm overall size.

• Double‑Triangular, Non‑Rock Hinged Lid: Two‑leaf design interlocks to prevent rattling or displacement under traffic.

• High‑Strength Ductile Iron: Manufactured to ISO 1083 standards for GJS materials, offering superior tensile strength and impact resistance.

Benefits for End Users

Engineered for extreme wheel loads, this cover resists deformation and corrosion, offering over 30 years of reliable service in harsh environments. The double‑triangular design and enlarged frame corners dissipate loads, reducing local stress and preventing cover movement under traffic. An anti‑slip pattern and sealed keyways maintain safety by preventing debris and water ingress. The hinged, two‑leaf lid enables quick, one‑person maintenance operations, significantly cutting labor time and downtime.

Installation & Maintenance

The drop‑in, self‑aligning frame seats flush in a prepared masonry surround, requiring minimal levelling during installation. Routine maintenance consists of inspecting hinge pins, lubricating locking bolts, and clearing debris from vents—tasks completed in minutes to minimize operational disruption.

Compliance & Quality Assurance

Manufactured in ISO 9001‑certified foundries and validated by third‑party BSI Kitemark and AFNOR NF testing for load, slip, and fatigue performance. Conforms to UK Highways Agency standards HA104/09 and DMRB CD534 for highway installations.
