10T Overhead Travelling Crane & Gantry: Renewable Energy Development, Orkney

A previously used double girder electric overhead travelling crane was modified, overheauled, delivered & installed. This was for our Orkney based client, Scotrenewables Tidal Power Ltd. The aim of the crane was to assist with the outfitting of their unique Tidal Turbine.

Special measures had to be taken to coordinate the transportation of the crane components, plant & materials to site due to the remote location. At Harold Potter Ltd, we relish the thought of a challenge. We stepped up to the mark to deliver the crane on time and precisely to the client’s specification.

The crane (as seen in photo) is a 10 tonne Safe Working Load Demag overhead travelling crane with a span of 10mtr, 5mtr Height of Lift and has a 12mtr length free standing gantry. The cross travel motors were fitted with inverter drives to allow for precise positioning of the hook for delicate operations.

FABRICATION FACILITY UPGRADE: METAL & STEEL FABRICATION AND MANUFACTURERS, NOTTINGHAM.

 

A previously used 25 tonne SWL double girder Demag overhead travelling crane was overhauled, supplied & installed for our Nottingham based client. This was to accommodate their expansion requirements.

The crane bridge length was modified to suit the existing gantry then cleaned and painted. The cross travel electrics were replaced for new equipment as is the standard of all our previously used cranes. All long travel and cross travel motors including the wire rope hoist were serviced and underwent a Report of Thorough Examination before leaving our workshop. A new control panel was made by our electricians to incorporate inverter driven cross and long travel motions. This enabled soft start and stop to allow for precision handling of loads. A radio remote control system was fitted to the crane to enable safe operation of the crane, from any location within the facility. Due to the size of the crane and restrictions within the facility, a mobile crane was required to lift the overhead crane into position. This was done by temporarily removing panels from the roof.

Installation of 2×25 tonne SWL Overhead Travelling Cranes, for our friends at FP McCann, at their Littleport depot. These cranes were double girder cranes.

The new cranes were installed complete with safety functions such as anti collision sensors, and slow down limits, to prevent any collision with either crane or end stop. The inverter control on the bridge travel was installed to have precise control over travel speeds, acceleration and deceleration. The Magnetek flex wave wireless remote control was installed, for ease of use.

The 25T crab units were supplied with the crane to meet customer lift speed specification. It also included slow down limit switches to prevent and collision with end of bridge beam. The cranes will be used for the production of concrete slabs for use in pre built housing. As well as various other concrete applications.

We also installed a further 10×25 tonne Gurulp Overhead Travelling Cranes, at the same site in Littleport, which you can see below.
