Description
Product Overview
The P12E fixing angle, part number A-22101-39, is a foundation anchor component for tower cranes. Cast into the reinforced concrete foundation, it forms the base connection onto which the first tower mast section is bolted, carrying the crane’s loads safely into the foundation. It is a key replacement spare part for securing the tower structure.

Compatibility
This page does not list a specific crane brand or model. To confirm fit, compare the model (P12E) and part number (A-22101-39) with your crane’s parts manual or foundation drawings, checking the mast section size and bolt-hole pattern before ordering.
Manufacturing & Quality
Manufactured from selected Q345B structural steel, each fixing angle is processed by overall sand blasting for a smooth, clean surface, then finished with high-quality anti-corrosion paint for strong adhesion and long service life. All welded joints pass weld inspection including X-ray and UT ultrasonic testing.
Frequently Asked Questions
Is this fixing angle reusable or single-use?
Fixing angles are embedded in the concrete foundation and are generally single-use — they remain in the foundation when the crane is dismantled. New fixing angles are required for each new foundation.
How is it installed on the foundation?
The fixing angle is positioned in the foundation formwork, levelled and secured against the reinforcement, then cast into the concrete. After the concrete cures, the tower mast section is bolted directly onto it.
What pins or accessories are included?
The fixing angle is supplied as the structural anchor component only. Connecting bolts and pins for the mast joint follow the crane manufacturer’s specification — please confirm what you need when ordering.
How do I confirm it fits my crane?
Match the model (P12E) and part number (A-22101-39) against your crane’s parts manual or foundation drawings, checking the mast section size and bolt-hole pattern.
Fixing angle vs foundation anchor vs anchorage frame — what is the difference?
A fixing angle and a foundation anchor are the same kind of component: the base part that anchors the mast to the foundation. An anchorage frame (tie-in frame) is different — it ties the crane mast to the building structure at height.
