What Is the Working Principle of a Construction Hoist Roller? A Construction Hoist Roller—also known as a guide roller or mast roller—is a key mechanical component used in rack-and-pinion construction hoists (building elevators). Its primary function is to ensure smooth, stable, and aligned movement of the hoist cage along the mast section during vertical travel. ✅ Working...

Principle of Horizontal Movement and Luffing of Tower Crane Trolley Trolley Traveling Mechanism The tower crane trolley achieves horizontal movement (left and right) through its traveling mechanism. The principle behind this is that the chassis of the trolley, consisting of a pair of drive wheels and a pair of fixed wheels on each side, is driven by a motor. This motor's power is...

Can Suspended Platforms Replace Traditional Scaffolding? Suspended platforms are generally divided into two types: manual (foot-pedal) suspended platforms and electric suspended platforms. They are a new type of high-altitude operation equipment that can reduce labor intensity, improve work efficiency, and be reused. Currently, the use of electric suspended platforms has gradually become a...

Comprehensive Analysis of Construction Hoist Safety Devices and Their Importance Construction hoist safety devices include anti-fall safety devices, upper and lower limit switches, emergency braking devices, etc. These devices work together to ensure the safe operation of construction hoists and reduce the risk of accidents. Construction hoists, as indispensable equipment in construction...

Tower crane protection devices include travel limiters, overload protectors, wind speed monitors, tilt protectors, and more. Travel Limiters Travel limiters are safety protection devices that control the travel of tower cranes. They can detect the travel between the main gear and the brake of the crane during operation. When the crane reaches the set travel limit, it can automatically stop...

How Many Years After Leaving the Factory Should Construction Hoists Be Scrapped? The general service life of a construction hoist is 8 years. After this period, a safety assessment is required, and the decision on whether to scrap it is made based on the assessment results. For specific models of hoists, such as SC construction hoists with a service life exceeding 8 years and SS...
