High Quality Shot Blasting Tower Crane Standard Mast section

Introduction

This series of the mast section of tower crane, has a horizontal jib frame, a jib-trolley radius-changing mechanism, and a hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all necessary safety devices, these mast sections of tower crane show a good speed-control capacity, satisfactory operating stability, and high work efficiency. This mast section of tower crane can be widely used for the construction of high-rise hotels, residential buildings, high-rise industrial buildings, large-span factory buildings and tower-like buildings like tall chimneys.

 

Common model of tower crane

The mast is made up of four pieces of mast sections connected by pins, and it is easy to install, dismantle and transport.

The details are as following:

Adopting advanced technology and the size is according to your requirement or drawing

1. High precise fixture and durable main steel frame
2. Good qualified raw materials and strict producing techniques
3. GB/T19001-2000-ISO9001:2000 certificate of quality
4. Adopt international standards approval certificate
5. Adopt Welding Robort to weld, reliable in quality and elegant in appearance.
6. Square steel frame: the connection plates between pipe rails are bent by a large machine. The bent steel is firm, good verticality, stability. Moreover, it ensures the stability of the whole structure.
7. All the structure adopt Tooling fixed technology to ensure stable performance and stability
8. The mast section (the color is variable) is made of a seamless pipe. (The high-quality seamless steel pipe is good verticality, anti-pressure, anti-aging, thickness and so on)

 

Mast Sections Main Materials: 

1) High-quality steel plate Q235 bent by special machine: Thickness 5mm

2) Welded steel tube Q345B ( Seamless steel tube 20# is also available): Ø76×4.5mm or Ø89×4.5mm  (Thickness of 6mm or 8mm is also available)

Spray paint Specifications: 650*650*1508mm

Galvanized   Specifications: 650*650*1508mm

         

 

Features

1. Raw material area

The pretreatment of raw materials and the blanking process is the basis of quality control. The raw material Q345B, Q235B from Chinese well-known factories such as Ansteel, Baosteel, to ensure high quality and safety.

2. Automatic robot machine

The automatic robot machine makes the welding joint more stable, straight and effectively improved productivity. 

3. Shot blasting

All products and pots shot blasting process before painting to ensure the surface smoother and beautiful.

4. Painting

High-quality polyurethane material is the absolute priority,the paint processed by two layers of primer one time of finishing a painting to ensure the anti-corrosion protection, excellent adhesion, and long service life.
