Camlok manufactures several types of rail clamps including the MR and MRC multi rail clamps designed to facilitate the fast and safe bulk handling of rail sections, the RA and RP rail anchor and rail pulling range, the SCR screwlok, and the CR clamp, designed to lift single rails of most types The standard design of these clamps and grabs can be adapted to provide several additional options

Specifying the correct end of line attachment
To ensure maximum productivity, to minimise costs and to ensure a safe lift and successful outcome it is essential to specify the correct end of line attachment for a specific lifting application

With the newly formed "Construction Division" of the Health and Safety Executive set to target the construction industry the safe handling of overhead loads has never been more important.
The CRH hydraulic rail clamp was designed for a client who needed to lift 180m long single sections of rail.
The clamps where suspended along a lifting unit by the hookring.
For such long lengths of rail 30 clamps where required and could simultaneously be opened or closed via the hydraulic system.
The design of the clamp was such that if during a lift pressure was lost or the hydraulic system failed the mechanical linkages would maintain the clamps grip and the clamp would hold the load safely.
Recently Camlok was asked to design, manufacture and supply nine rail grabs for export, that were capable of lifting 110m lengths of rail in one operation.
The grabs were to be incorporated into an overhead hoisting system which would be a vital part of a major rail network refurbishment.
The grabs had to be capable of being operated by a single person situated some distance away.
Camlok based the design on its MRC clamp incorporating a solenoid device to open and close the grabs and an interchangeable comb to suit various sizes of rail.
The solenoid enabled one person to simultaneously operate all the grabs.
During the design process an American client asked Camlok to produce six rail grabs that were capable of performing similar tasks to the MRC.
Due to varying design specifications, the solenoid solution would not be practical, so Camlok designed a mechanical solution.
Like the solenoid MRC this grab had interchangeable combs for different sized rails but the grabs could be operated via an automatic mechanical open and close device.
Both adaptations of the MRC rail grab successfully fulfilled the requirements solving two problems with similar applications.
