Description
Product Overview
The P62B Tower Crane Fixing Angle is the foundation anchor that secures the tower crane mast to its concrete foundation. Installed during foundation construction, the fixing angle is cast into the concrete so that its four legs protrude from the finished slab at the correct bolt pattern. The first P62B mast section then bolts directly onto the fixing angle, giving the entire crane a rigid, perfectly plumb base to stand on.
As a replacement spare part, this fixing angle is built to the original P62B geometry — leg spacing, base plate dimensions, and bolt-hole pattern — so it drops into existing foundation designs without modification. It carries the full overturning moment, shear, and vertical loads of the crane down into the concrete, which makes dimensional accuracy and weld quality critical to safe operation.

Compatibility
This fixing angle pairs with P62B mast sections — the same P62B designation used for the corresponding tower crane mast sections (this page is tagged Potain). The mast section’s base bolt pattern must match the fixing angle’s leg positions, so always verify your mast section model and foundation drawings against the specifications above. No cross-brand compatibility is claimed beyond what is stated here.

FAQ
Is this fixing angle reusable or single-use?
This is a standard, single-use fixing angle: once cast into the concrete foundation it stays with it for the life of the structure. (For a removable option, see our R20A reusable fixing angle.)
How is the fixing angle installed on the foundation?
The fixing angle is positioned and leveled on the reinforcement cage before the foundation concrete is poured, with its upper legs protruding to receive the mast section. Correct leveling and secure bracing during the pour are essential so the crane erects plumb.
What pins or accessories are included?
This fixing angle is supplied as a complete welded assembly. Confirm any additional foundation hardware you need with your sales contact before ordering.
How do I confirm it fits my crane?
Check that your mast section is a P62B type and compare your foundation drawing’s bolt pattern and base dimensions with the specification table above. Send us your foundation drawing if you are unsure.
What is the difference between a fixing angle and a foundation anchor?
The two terms are used interchangeably: a fixing angle (also called a foundation anchor) is the steel frame cast into the concrete that the crane mast bolts onto. Unlike a cross-base or undercarriage, it has no moving parts and remains permanently in the foundation.
