Genie Mast Stiffener, Left, Blue - OEM Number: 109578Gt

The Genie Mast Stiffener, Left, Blue (OEM 109578GT) is a genuine replacement structural mast component designed for use on Genie Superlift Advantage (SLA) material lifts. It forms part of the telescopic mast assembly, providing additional rigidity and support while guiding the mast sections during lifting and lowering operations. Genie parts manuals identify 109578GT as the left-hand blue mast stiffener, working in conjunction with the corresponding right-hand stiffener and associated rollers and spacers.

Manufactured to OEM specifications, this mast stiffener is engineered for strength, dimensional accuracy, and long-term durability. It is designed to withstand repeated lifting cycles, heavy loads, and demanding site conditions while maintaining correct mast alignment and smooth operation of the lifting system.

FUNCTION AND OPERATION

• Provides structural reinforcement to the mast assembly
• Maintains correct alignment of telescopic mast sections
• Supports smooth lifting and lowering operations
• Works with mast rollers and spacers to minimise wear
• Helps maintain lifting stability and load control
• Designed for demanding construction and material handling applications

TECHNICAL DETAILS

• OEM Part Number: 109578GT
• Type: Left-hand mast stiffener
• Colour: Blue
• Function: Mast reinforcement and alignment component
• Application: Genie Superlift Advantage (SLA) material lifts
• Construction: Heavy-duty fabricated steel component
• Design: OEM-configured left-hand mast stiffener for direct replacement installation

Genie parts documentation lists 109578GT as "MAST STIFFENER, LT, BLUE", used alongside the right-hand stiffener (109577GT), mast spacer (33843GT), rollers, and mounting hardware.

TYPICAL APPLICATIONS

Suitable for a range of Genie material lifts, including:

• Genie SLA-5 Superlift Advantage
• Genie SLA-10 Superlift Advantage
• Genie SLA-15 Superlift Advantage
• Genie SLA-20 Superlift Advantage
• Genie SLA-25 Superlift Advantage
• Telescopic mast lifting assemblies

The left-hand mast stiffener is a key structural component within the SLA mast assembly, ensuring proper rigidity and reliable load handling performance.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and orientation before ordering, as 109578GT is the left-hand blue mast stiffener and is not interchangeable with the right-hand version (109577GT) or later grey variants. A bent, cracked, or damaged mast stiffener can affect mast alignment, increase roller wear, cause uneven lifting, and compromise the safe operation of the material lift. When replacing the stiffener, it is recommended to inspect the mast rollers, spacers, fixing hardware, and adjacent mast sections for wear or damage to ensure smooth operation and long-term reliability.
