The National Crane 9125A boom truck crane was originally part of the Series 900A product lineup.  It is equipped with a 36.2' to 125' (11.02 m -38.10 m) four-section main boom and the maximum tip height is 134' (40.84 m). tHIS model has a 26 USt ton (23.6 mt) lifting capacity with self-lubricating “Easy-Glide” wear pads and an internal Anti-two-block patent-pending design that comes standard on the Series 900A eliminating an external reel and wire. No more snagging reel or wire on obstructions.

Adjustable Swing Speed – A control knob located on the swing motor brake release valve can be easily adjusted to the crane operator’s swing speed preference. 

Speedy-reeve Boom Tip and Sheave Blocks – These standard features simplify rigging changes.

Pre-painted Components – Painting crane components before assembly reduces the possibility of rust, improves serviceability, and enhances the appearance of the machine.

Burst-of-Speed Winch – Provides faster winch payout and pickup of unloaded cable.

Improved Serviceability –  A removable winch allows the internal telescoping cylinder to be removed quickly, without dismantling the boom.

– Bearings on the boom extend and retract cables can be greased through access holes in the boom side plates.

– Internal anti-two-block wire routing eliminates damage potential.

– The boom sheave case is open, allowing access to replace the internal anti-two-block wire and to observe internal boom components.

– Pre-paint reduces rust.

– Internal boom parts have been reduced, decreasing service time when rebuilding the machine.
