SJY PULAITE Manual Winch Aluminum Alloy Square Lifting Mast

Description:

This manual-winch telescopic mast sets new industry standards with innovative design. Supporting internal wiring, it can be installed with lights, antennas, warning horns, megaphones, and monitors. Using aluminum components instead of steel reduces weight by over 50% and shortens the closed height significantly. For example, a 7-meter mast is only 1.7 meters in height when closed. Oxidation treatment makes the rod corrosion-proof and rust-resistant, while enhancing its visual appeal. The built-in steel wire rope improves aesthetics and safety, with a cross-arranged, double-sided "double insurance" structure ensuring stability even in case of partial breakage.

Product selling points:

1. Unique development: The world's only manual-winch telescopic mast with internal wiring, capable of carrying equipment such as lights, antennas, warning horns, megaphones, surveillance cameras, and lightning rods.

2. Square mast design: The square profile effectively prevents self-rotation, and the thickened inner wall greatly enhances wind-resistance ability. It can stand independently in a 6-level wind without the need for guy ropes.

3. Comparison with other materials: Compared with steel masts, this aluminum manual mast is more than 50% lighter and with a shorter closed height.

4. Product advantages:

● Mast body material treatment: The surface of the mast is oxidized, non-corrosive and rust-proof during marine transportation.

● Appearance and performance: The built-in steel wire rope is lightweight, enhancing both the aesthetic appeal and anti-corrosion performance.

● Equipment wiring: It supports internal wiring; for example, four power cables and two network cables can be built in.

● Steel wire wiring: All core routes have internal steel wire, with a cross-structured internal design.

● Weight and height: The closed height of this hand-crank mast is significantly shortened. The maximum lifting height can be customized to 7 meters while the closed height is only 1.7 meters, and the mast pole weighs only about 25 kilograms — more than 50% lighter than steel equivalents. It is convenient for transportation, while competing products require disassembly of the mast for transportation.

● Safety factor: The multi-stage steel wire and pulleys form a double-sided steel wire system. Even if one side breaks, the other side can still ensure safety, reducing the probability of dropping.

Steel Wire Version:

★ Our recommendation: compared with the steel wire version, the webbing lifting system is simpler in structure and easier to replace on site, making maintenance quicker and after-sales service easier.
