• Demag open winch wire rope units fit the bill
• Precision movement and positioning of large and heavy loads
• Strong Demag regional service support
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’s product range includes sub-sea and surface trees and tubular components, which are distributed to major oil and gas operators worldwide.
Dril-Quip specified the Demag cranes as part of an expansion programme at its 400,000 sq ft 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, which are particularly suited to Dril-Quip’s manufacturing processes.
Both cranes 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.
Dril-Quip Europe’s Lifting Equipment Supervisor, Arty Matheson, reported that the company now has several Demag cranes at its Aberdeen production facility:
“We have been impressed by the productivity and reliability of our existing Demag cranes. This latest investment was prompted by the necessity to handle increasingly large and heavy loads. Terex Material Handling was able to help us meet these objectives with an engineered solution, tailored to our specific requirements, incorporating the Demag MPW open winch wire rope lifting units.”
“Demag’s regional after sales network was also an important factor in the specification process. Demag service has a strong presence in the north east of Scotland, providing us with total peace of mind in terms of technical support.”
