Terex Material Handling has installed two Demag overhead travelling cranes at Dril-Quip Europe’s production facility in Aberdeen.
A division of the multinational operator, Dril-Quip Inc of Houston, Texas, the company designs, manufactures and services a wide variety of hardware for the oil and gas industry.
Dril-Quip specified the Demag cranes as part of an expansion programme at its production facility. The investment was driven by the need to handle increasingly large and heavy components, between manufacturing and assembly processes. Terex Material Handling supplied a Demag 50 t SWL, 17.6 m span ZKKW double girder overhead travelling crane and a 30 t SWL, 17.6 m span ZKKW double girder overhead travelling crane.
Both cranes incorporate Demag MPW open winch wire rope lifting units and have variable cross and long travel speeds of 0 - 20 m/min. The 50 t SWL crane has variable hoisting speeds of 0 – 8.8 m/min for loads up 30 t and 0 – 5.5 m/min for loads above 30 t, whilst the 30 t SWL crane has variable hoisting speeds of 0 – 8.8 m/min for loads up 18 t and 0 – 5.5 m/min for loads above 18 t. Safety features include fast to slow and slow to stop functions at cross travel and long travel limits, with an optical crane to crane anti-collision feature.
The crane systems feature AC inverter controls for smooth movement, precision positioning accuracy and minimisation of load sway. The cranes are operated via a Demag DRC-J joystick radio remote control, allowing the operator to be excluded from the lifting area for safety, ergonomic efficiency and comfort.
