In modern construction, efficiency and safety are crucial factors. As an innovative piece of construction equipment, attached construction hoists are gradually replacing traditional construction hoists and scaffolding, becoming a new favorite in high-rise building construction. Compared to other products, what advantages do they offer in different application scenarios?

Traditional Construction Hoists (SC/SS)

Traditional construction hoists, particularly the SC rack-and-pinion and SS wire-rope hoists, are common equipment in high-rise building construction. They enjoy a high reputation in the industry for their stable performance and fast speeds. They can carry both people and cargo, are fixed to the building's exterior wall via wall mounts, and rise in sections as each floor rises.

However, compared to traditional attached construction hoists, SC and SS hoists require incremental increases in height, increasing construction time and cost. A new section of track is required for every 7-8 meters of construction, requiring 20 high-altitude installation and removal operations for a 150-meter-high building. This can also lead to downtime for tower cranes, potentially compromising construction safety. Furthermore, these devices require additional scaffolding during exterior wall construction, separating personnel and cargo. This secondary handling accounts for 15% of the construction period, increasing construction complexity and costs.

Attached Lifting Scaffolding (Climbing Frame)

Although not classified as an "elevator," attached lifting scaffolding, commonly known as "climbing frame," overlaps in functionality with attached construction elevators in high-rise exterior wall construction, making it an indirect competitor. Climbing frames are primarily used as exterior wall construction platforms. Their lifting and attachment methods are similar to those of attached construction elevators: they are both raised and fixed to the building structure.

However, the main difference between climbing frames is that they cannot carry personnel or cargo; they serve solely as a construction platform. This limits their application to a certain extent, making them limited to "springboards" and unable to transport bricks, pipes, or personnel. Materials must be lowered to the floors by tower cranes, which creates a high risk of cross-operation. Especially in applications requiring vertical transportation of personnel and materials, their functionality is inferior to that of attached construction elevators. Advantages of Attached Construction Hoists

Attached construction hoists utilize a "guide rail + rack + attached support" structure to create a self-climbing "steel backbone," solving both transportation and operation challenges simultaneously. This allows for integrated lifting, eliminating the need for floor-by-floor height increases and significantly reducing construction time and costs. The guide rail serves as both the rack and the climbing track, combining permanent structure with temporary equipment. Driven by an electric hoist or hydraulic cylinder, it "steps" two or three floors at a time, completing a climb in 30 minutes. The elevator can carry up to 2 tons and 24 people, allowing masonry, curtain wall, and electromechanical materials to be delivered simultaneously, with both personnel and cargo contained within the same cage, improving construction efficiency. Equipped with multiple safety features, such as a fall arrest device and intelligent control system, these features enhance construction safety, enabling faster, more cost-effective, and safer construction of buildings over 100 meters tall.
