Tower Crane Anchorage Frame

Description

Product Overview

The Tower Crane Anchorage Frame is a critical structural attachment component for tower cranes. Made of high-strength steel with heavy-duty welded construction, it connects the tower crane mast section to the building structure, reinforcing overall crane stability when the crane exceeds its free-standing height. With robust load-bearing performance and an anti-rust painted finish, it is reliable for high-rise construction site heavy-load working conditions.

Specifications

• Product: Tower Crane Anchorage Frame
• Type: Anchorage frame (tie-in / attachment frame)
• Material: High-quality Q345B / Q235B steel
• Construction: Heavy-duty welded construction, gas-shielded arc welding
• Inspection: Weld inspection, X-ray and UT ultrasonic inspection
• Surface treatment: Sand blasting with anti-corrosion / anti-rust paint finish
• Included: Complete connecting pins and bolts

Product Advantages

1. Sized for L68B2 / L68B3 C-frame masts

The frame is tagged for C-frame mast sections such as L68B2 and L68B3, commonly used on Potain-type tower cranes. Matching the frame to your mast section type and tie-in drawings before ordering ensures the clamps seat correctly on your mast profile.

2. Ships with complete connecting pins and bolts

Unlike foundation anchors, this anchorage frame is supplied with complete connecting pins and bolts as standard. You can install it straight from the crate without sourcing separate hardware or guessing at the correct fastener sizes.

3. Heavy-duty welded frame with verified weld quality

Built from Q345B / Q235B structural steel with heavy-duty gas-shielded arc welding, every joint passes weld inspection including X-ray and UT ultrasonic testing. The sand-blasted anti-rust paint finish stands up to outdoor high-rise site conditions while the frame transfers horizontal loads from the mast into the building structure.

Compatibility

This anchorage frame is tagged for C-frame masts such as L68B2 / L68B3 and is associated with Potain-type tower cranes. To confirm fit, compare the frame size, mast section type and connection dimensions with your crane’s tie-in drawings before ordering.

Manufacturing & Quality

Manufactured from selected Q345B structural steel with heavy-duty welded construction, each anchorage frame is processed by thorough sand blasting and finished with anti-corrosion paint for strong adhesion and long service life. All welded joints pass weld inspection including X-ray and UT ultrasonic testing.

FAQ

Q1: Are you a manufacturer or a trading company?

A1: We are a manufacturer specializing in tower crane steel components. Additionally, we act as an integrated supplier for other construction machinery and spare parts to provide a one-stop sourcing solution for our clients.

Q2: What is your standard delivery time?

A2: For items in stock, we can ship within 1-2 business days. For bulk orders or customized products, the lead time is typically 15-25 days, depending on the order volume.

Q3: How do you ensure product quality?

A3: Quality is our priority. We implement strict pre-shipment inspections for every order. Furthermore, we offer a 1-year warranty to ensure our clients’ peace of mind.

Q4: What are your packaging standards?

A4: We use standard export seaworthy packaging, including robust wooden cases and reinforced cartons. They are specifically designed to withstand the rigors of long-distance international shipping.

Q5: Which shipping methods do you support?

A5: We support multiple shipping channels, including Sea Freight (LCL/FCL), Air Freight, and International Express (DHL/FedEx/UPS), to meet different urgency and budget requirements.

Q6: Which tower cranes does this anchorage frame fit?

A6: It is tagged for C-frame masts such as L68B2 and L68B3, and associated with Potain-type tower cranes. Confirm fit by checking your mast section type, the frame size, and connection details against your crane’s tie-in drawings and parts manual before ordering.

Q7: When is an anchorage frame needed instead of just a foundation anchor?

A7: A foundation anchor secures the base of the crane, but once the mast rises past its free-standing height it needs lateral support. The anchorage frame clamps around the mast at the designed tie-in level and its struts connect to the building structure, transferring horizontal loads into the building so the crane can safely operate at high-rise heights.

Q8: Can this anchorage frame be reused on another project?

A8: Yes. Unlike fixing angles, which are permanently buried in concrete, the anchorage frame clamps around the mast above ground and is removed when the crane is dismantled. As long as the frame, pins, and bolts are inspected and found sound, it can be reused on another project with a matching mast type.
