Portal overhaul Vattenfall
Conversion and overhaul portal crane water intake station Vattenfall
The gantry crane with a lifting load of 65 tons and an auxiliary hoist of 12.5 tons was in need of an overhaul. Especially the control boxes were affected by the salty climate. A complete new stainless steel 316 box was engineered by Tol Company from Volendam. The existing mounting plates with controls were remounted. The ventilation and standstill heating was improved. The coupling cabinets were also replaced with stainless steel 316 cabinets and the standstill heating installed.
A new Teleradio radio control was delivered and integrated into the control system. This shows the current load. The limit switches such as for crane travel, cat travel and end of line switches have been replaced.
The wind meter and protection has been replaced with a new Sole Digital wind protection and signaling system.The lower blocks have been overhauled, re-lubricated and re-certified.
The overhaul means the controls can last for years again! To protect the machine work of the hoists, a full roof was mounted on top of the cat. The job was performed and completed to the full satisfaction of Vattenfall.
