DEHA Spherical Head Lifting Anchor System

Product catalog summary

Introduction
The DEHA Spherical Head Lifting Anchor System by HALFEN is engineered for high performance and safety in concrete lifting applications. It utilizes specially tempered steel to ensure high ductility and cold-toughness, complying with DIN EN 10025 and the European machine guideline (MD) 2006/42/EC. Consistent product quality is maintained through regular quality control.

System Overview
The system comprises various anchor types, including spherical head anchors for beams, walls, slabs, and specialized applications like sandwich panels and thin-wall elements. Each anchor type is tailored with specific load classes and features to meet diverse construction needs.

Installation and Application
Comprehensive instructions are provided for the installation and application of the anchors, ensuring compliance with VDI/BV-BS 6205 standards. The system is applicable in utility-pipe projects and tunnel construction.

Design Calculations
The catalogue includes design calculations to aid in selecting the appropriate anchor type and load class for specific applications.

Recess Formers and Accessories
Various recess formers and fillers, including rubber, steel, and magnetic options, are available to accommodate different anchor types and ensure proper installation.

Lifting Links
The DEHA Universal Head-Link and Small Universal Head-Link are compatible with all types of spherical head anchors, supporting a wide range of load classes.

Selection Tables
Detailed selection tables provide information on available anchor types, load classes, and finishes (mill finish, hot-dip galvanized, stainless steel A4), facilitating precise specification and ordering.

Safety Regulations
The transport anchor system consists of a permanently cast-in anchor and temporarily connected lifting equipment. Compliance with VDI/BV-BS guidelines 6205 is ensured, and quality control is conducted according to DIN EN ISO 9001 and RAL Quality Assurance specifications.

Technical Specifications
Key factors for anchor selection include load capacity, edge spacing, concrete grade, load direction, and additional reinforcement. Formulas for calculating tension loads are provided, emphasizing the importance of correct anchor layout and the number of load-bearing anchors.

Load Calculations
The document details the calculation of tension forces on anchors, considering factors such as spread angle, dynamic loads, and adhesion to formwork. Tables for spread angle factors and dynamic factors are crucial for determining load capacity during lifting operations.

Adhesion and Load Distribution
The document discusses the impact of adhesion to formwork and provides guidelines for minimizing it. It also explains the importance of using spreader beams for achieving perfect static weight distribution and ensuring even load distribution across multiple anchors.

Specifications
The document outlines the load capacities of spherical head anchors in beams, walls, and slabs, with specific attention to concrete strength and wall thickness. It specifies conditions under which diagonal pulls are permitted, emphasizing concrete strength and minimum wall thickness.

Load Capacities
Load capacities are detailed for different load classes and concrete strengths, with tables providing specific values for axial and diagonal pulls. Diagonal pulls with a spread greater than 60° are not permitted.

Reinforcement Requirements
The document specifies the reinforcement needed for different load classes, including U-bar stirrups and square mesh reinforcement, emphasizing proper reinforcement placement, especially for diagonal pulls.

Dimensions
Detailed dimensions for spherical head anchors and rod anchors are provided, including mill finish and hot-dip galvanized options.

Recommendations
Best practices for installing anchors include ensuring full contact with the anchor and placing diagonal reinforcement close to the recess former. Certain configurations require specific reinforcement to handle loads effectively.

Limitations
Lifting loads resulting from cable spread within certain angles is not permitted. Diagonal pull with cables/chains spread beyond 60° is not allowed.

Best Practices
Additional reinforcement is suggested for certain applications, especially in thin reinforced concrete elements. Guidelines for installing additional reinforcement securely and ensuring full contact with the anchor are provided.

Key Data from Tables
Tables provide critical data on load capacities for different anchor types and configurations, specifying the minimum element thickness, axial spacing, and concrete strength required for safe operation.

Installation Procedures
The installation process involves placing the anchor into a recess former, which is then attached to the formwork. Correct orientation and positioning of the anchor are crucial for proper load distribution.

Recess Formers
Various types of recess formers are described, including rubber, steel, and polyurethane options, each designed for specific applications and load classes.

Norms and Recommendations
Annual inspections of lifting links by qualified experts are required, and damaged lifting equipment must not be used. Mixing HALFEN products with non-HALFEN products is discouraged.

Accessories and Load Classes
Detailed tables list load classes, dimensions, and order numbers for various components, including universal head lifting links and small lifting links.

Safety and Identification
Each lifting link is marked with a unique identification number, load class, and manufacturer details to ensure traceability and facilitate safety checks.

Applications
The document describes the use of transport anchors in pipe-laying and tunnel applications, highlighting the installation of accident recovery units in road tunnels using spherical head anchors and universal head clutches.

Device Specifications
The device is equipped by the manufacturer to prevent the unintentional release of the clutch from the anchor. A chain with a dowel and a ring bolt is installed to prevent theft of the recovery anchor.

Usage Requirements
Reference projects are required from the manufacturer when using the spherical head anchor as an accident recovery unit in tunnels. All elements in the system must be from one manufacturer.

Technical Notes
Technical and design changes are reserved, and the information is based on the state-of-the-art technology at the time of publication. HALFEN GmbH does not accept liability for the accuracy of the information or for any printing errors.

Quality Management
HALFEN GmbH's Quality Management System is certified according to DIN EN ISO 9001:2008 for various locations in Europe.
