Windmill Safety Attachment Point Inspection

Mona Lifting were called upon to inspect safety harness attachment points on a windmill – Melin Llynnon, Ynys Mon, makes a change to usual work carried out on modern wind turbines!

Crane Replacement for DCCWW Lliw Valley Pumping Station

Mona Cranes replaced an old crane for DCCWW Lliw Valley pumping station to automate the process of servicing the pumps which are located in a sump 20m deep. The installation was complicated as conventional mobile cranes could not be used and a special lifting system designed by Mona was utilised for the installation.

Dulas Ltd, Balnacarn Powerhouse Crane

Dulas Ltd who specialise in small hydro installations contracted Mona Lifting to devise a crane that would lift a relatively heavy turbine in a small low headroom ‘rustic’ powerhouse building. Mona Lifting designed, manufactured and tested a 7 tonne x 3.8m span manual underslung overhead travelling crane to fit the parameters see drawing below.

Kellogs Ltd, Wrexham

Kellogs Ltd who operate a breakfast cereal manufacturing plant had twelve mixing machines in a headroom confined area which needed motors replacing periodically. An existing crane had been installed by another manufacturer but it proved to be unsatisfactory due to the long travel jamming under load. Mona Lifting were asked to replace the crane, so a new crane was designed SWL 2t x 2m span as per the drawing below. This crane is successful and is set to be repeated on each mixing unit.

Dawnus Construction Ltd, Cowlyd Lower Powerhouse Crane

Dawnus are constructing a powerhouse for Welsh Water’s Cowlyd reservoir outfall works this is the second crane on this project. Mona Lifting have manufactured several versions of this design of crane to other small powerhouses in Wales and Scotland.

The crane is a top running manual overhead travelling crane 5tonne x 6m span complete with support gantry and rails.

Stena Line Ltd, Re-Fuelling Jetty Pipe Bridge

Stena requested Mona Lifting to solve a problem they had at Holyhead Port where an existing ship fuel pipe support structure had become corroded and was in need of prompt renewal. Mona designed, manufactured, coated, and installed a 42m long steel lattice bridge structure using the MV ‘Mersey Mammoth’ Floating Crane in a tight programme so as to secure the integrity of the installation.

North Wales Dock Company, Bascule Bridge, Felinheli Dock

North Wales Dock Company Ltd who operated the Marina and Dock at Felinheli had problems with their Bascule Bridge which was badly corroded and mechanical drives and transmissions were worn causing problems in lifting and lowering the deck. Mona Lifting Ltd were called in to provide temporary repairs which entailed removing drives re – machining and bushing and applying an interim protective coating system to the bridge, so as to provide a safe and satisfactory operation.
