The Capstan Anchors are a safe, simple and effective system for lifting most types of precast concrete units. The anchors are hot drop forged from high grade steel and, provided the anchor is specified and installed correctly, provide safe and secure lifting, turning and transportation of units. Anchors are available in black, zinc plated, galvanized, 304 and 316 stainless steel.
The system consists of three main components, the anchor (also known as pins, spherical head or modform), a recess former and a lifting attachment known as a shackle that links the anchor to the crane hook. They are produced in load groups from 1.3t to 32.0t and there is a length and material to suit almost all precast units.
Each anchor is stamped with the manufacturers’ identification mark, safe working load rating of the anchor, the batch number and CE mark. Lifting shackles are also marked with the load group, CE mark along with the manufacturing date stamp and an individual index number for full traceability of the system. All products are rigorously tested, inspected and supplied with Declarations of Conformity with each order along with safe working instructions where applicable.
The design of the system prevents the mismatch of load groups, as only the appropriate shackle will fit the anchor it is intended to use.
Capstan Anchors are designed for de-moulding, pitching, transport and site fixing. It is likely that there will be numerous lifting operations from production to installation, so the handling at each point should be carefully considered at each stage, and an appropriate load group and length should be selected. These anchors should not be used for repeated lifting applications over a prolonged period of time. If pitching of the units is required with Capstan Anchors, please contact RFA-Tech for technical assistance.
1.3t-32.0t load groups and are suitable for large units such as staircases, slabs, wall units, beams and pipes.
