Ravestein specialises in the fabrication to installation of heavy steel constructions such as bridges, lock gates, roll-on/roll-off landing stages, jack-up platforms and backhoe dredgers, as well as all types of modular pontoons and ships. With their own engineers and craftsmen fully acquainted with international developments, they occupy a prominent position worldwide.
Our Relationship with Ravestein Equipment
We work closely with regards to Grimsby Fish Docks infrastructure and the ever-changing wear and tear requirements. Since 2005 we have maintained Ravestein’s sophisticated equipment on the docks. During this time Garrick Hickman and Shaun Polley have embraced the difficult task of learning about the 1930’s infrastructure of the Fish Dock Estate, with Shaun taking over this responsibility from Garrick.
Shaun has demonstrated passion and determination to improve and maintain the Town’s vital facility and has become an irreplaceable asset to Hickman Engineering and Grimsby Fish Dock alike, with 5 years of experience and knowledge working alongside Garrick with his ten years specialising in Ravestein equipment.
Working with Ravestein Machinery
We regularly provide comprehensive inspections of the lock gate equipment at Grimsby Fish Dock and perform services such as:
- Ravestein hydraulic repairs
- Improvements and modifications to make the Ravestein equipment bespoke to Grimsby Fish Dock Enterprises’ requirements
- Ravestein repairs and maintenance
- Bespoke Ravestein component manufacture
An example of a custom component is a manufactured rod lock support beam rollers. We work on both small and large-scale projects involving Ravestein machinery.
Ian from the Port of Grimsby is always satisfied with our work and said “Shaun and the team provide reassurance and round the clock support which is so valuable to our elderly infrastructure”.
Ravestein Equipment Maintenance
An example of one of our accomplishments includes the design, manufacture and installation of shoot bolt wedge blocks, and the manufacture of two improved rod lock support beam rollers back in June 2017.
Upon routine inspection, we found the existing steel roller had vulcanised rubber layers wrapped around it & subsequently the layers were deteriorating and peeling off. After discussions with the manufacturer, we found that this had been an issue on other Client locations. With new material instruction (Ecetal) we designed a bespoke new component which we then manufactured & installed utilising our design and expansive manufacturing capabilities.
Following the same inspection it was apparent that the sensor flags were on the rod lock wedges. These wedges are not an ideal location for a sensor indicator as these wedges move into various positions during operations. We then designed and manufactured new sensor brackets which then picked up the rod lock hydraulic cylinder eye. We found this to be a more robust area for the indicator to live.
The inspection also made it apparent that the shoot bolt sensors were located on a flag pole-style area external to the gate. This was found to be inadequate for the sensors to perform their function admirably. After a thorough investigation and brainstorm it was decided that utilising the shoot bolt rod inside the gate was a more substantial and robust position which increased functionality. We moved the sensors from outside the gate to inside positions and manufactured a new sensor indicator that attached to the shoot bolt rod.
