Generator Field Support Platform

Mechanical Dynamics & Analysis (MD&A) experts have constructed a generator field support platform to allow for removal of the field when performing a 7FH2 Generator Major Inspection.

Rotor field inspections can either be performed on-site or in a shop environment.  Repairs generally require the rotor field to be transported to a qualified repair facility. 

MD&A has developed a field pulling & support system to address the unique challenges associated with the 7FA/7FH2 configuration: 1) the shaft centerline height is 13 feet above machine baseline (grade), and 2) the gas turbine inlet ducting and filter house limit crane access.

The MD&A system consists of a modular work platform using adjustable rotor field trolley carts to efficiently and safely extract the field from the stator core, providing a stable work platform for on-site inspections and sufficient length to enable crane access to lift the field for off-site repair transportation.

Key features of the system include:

• Modular design work platform for expedited setup/teardown and efficient transportation on standard trailers
• Overall platform length and height can be adjusted based on site and workscope requirements
• Tongue and groove work platform connections and integrated trolley cart rail system provide seamless transitions between platforms
• Wide walkway wings on left & right sides enable worker & equipment access
• Modular safety rail system allows flexible scaffold stair access based on site arrangement
• Adjustable trolley carts use low-friction, self-guided rollers for safe and fast positioning of the field on the platform
• The system is very stable and is rated for continuous use with steady wind speeds up to 30 mph (with minimum 3x factor of safety)
