A pylon servicing apparatus comprising a carriage (11) having a first drive mechanism (17) provided on the carriage (11), the first drive mechanism (17) being adapted to engage the pylon (10) to enable the carriage (11) to be moved longitudinally along the pylon (10), the carriage (11) supporting a housing defining a space, the housing having two opposed end walls and at least one side wall extending between the end faces, the end faces having inner edges (30) being configured to be receivable about the pylon (10), the housing being divided axially into at least two portions (13) which are pivotally interconnected to be movable between a closed position defining the space and an open position, a second drive mechanism (16) provided between the portions (13) to enable the movement between the open, and closed position, wherein when the portions (13) are in the closed position they can cooperate with the pylon (10) to form an annular space surrounding the portion of the length of the pylon located between the end faces and when in the open position the housing can be moved into and out of engagement with the pylon (10), a first sealing mechanism (32) provided on the inner edge of each end wall and adapted to be sealingly engageable with the pylon (10) when the portions (13) are in the closed position and a second sealing mechanism (27) provided on the abutting edges of each portion (13). The second sealing mechanism on one portion is adapted to be sealingly engageable with the second sealing mechanism (27) on the adjacent portion when the portions (13) are in the closed position.
