Product Overview

The Mast Section L46A1 is a standard 1.6-meter series mast section primarily used in construction hoists and tower cranes. It is designed for medium to large tower crane models, providing the structural height and rigidity needed for mid- to high-rise construction projects. It is known for its panel design, which allows for easy installation and efficient transport compared to monobloc structures.

Key Technical Specifications

The table below aggregates the standard specifications for the L46A1 model from multiple suppliers:

Key Features & Design

• Structure: Features a “panel design” (split structure/bolted connection). A standard mast comprises 4 panels: two with telescoping lugs and two without. Panels with ladder fixing gussets must be installed face to face.

• Assembly: Panels are assembled using 20 special fishplates per case, with bolt heads placed on the outside for safety and inspection ease.

• Manufacturing:

  • Steel: Main chords and diagonal struts are made from special square steel pipes and angle steel (Q345B) from major steel enterprises.

  • Welding: Gas-shielded welding (80% Argon + 20% CO2) is used, with quality verified via X-ray and UT ultrasonic inspection.

  • Surface: Treated with a shot blast process to remove rust and increase paint adhesion, followed by anti-corrosion painting for durability.

Compatible Crane Models

The L46 mast section is widely used with several specific tower crane models. Notably, it is the standard mast for the Potain MC115, MC120, MC170, and MC175 models. It is also used in Chinese models such as the QTP6013 (flat-top crane) and various models from manufacturers like Zoomlion.

Shipping & Logistics

• Packaging: Typically shipped in nude/carton packaging or bundled on pallets. The compact 1.6×1.6m footprint allows for high density loading (approx. 15 units/40HQ).
