Working for the Flotte Hamburg
Crane overhaul and upgrade of the arm to 5 extensions
The Flotte Hamburg GmbH & Co. KG (Hamburg fleet) is a 100% subsidiary of Hamburg Port Authotity AöR (HPA) to fulfil the integral fleet management of the ships of the Freie und Hansestadt Hamburg. Heila recently carried out a crane overhaul and arm extension for the Flotte Hamburg.
The jib was severely bent and also part of the hydraulics suffered considerable damage. Flotte Hamburg quickly decided to have the crane repaired by Heila. Heila took care of the dismantling and transport to the workshop in Waalwijk, the Netherlands. There, the crane was stripped down entirely and all necessary parts were replaced. In the meantime, the Flotte Hamburg also decided to have the crane arm upgraded to 5 extensions. The overhaul and expansion went smoothly, and the crane was repainted in an other colour, giving the crane a completely new look.
The FAT test was performed in the presence of our representative in Germany, Hans van der Kuy. Following the customer’s acceptance the crane was transported to the Port of Hamburg and installed on a workshop barge. The installation was carried out by the customer and Heila was present for the commissioning.
The customer uses the crane on a barge located along the quay side of the workshop. Spare parts and components are unloaded here before being transported to a workshop placed adjacent to the pontoon, where repairs and overhauls are carried out.
Keeping the port safe to navigate
Because of tidal differences, the Port of Hamburg needs to monitor the water depth in various areas regularly. For this purpose Flotte Hamburg uses a dredger which is mounted on a flexible adjustable stilt pontoon called ‘Modi’. This pontoon is suitable to remove silt and mud or other obstacles from the bottom also in areas which are very difficult to reach. The pontoon carrying out the dredging work could be in a standstill position for longer periods. To keep the ‘Modi’ in place, anchor legs are lowered through holes in the corners of the pontoon. Lifting and lowering the anchor legs requires a crane. The Flotte Hamburg has also ordered a crane from Heila for this: an HLRM 80-3S with winch which is also suitable for handling on a workboat.
