The elevator installation platform is a core component of elevator installation projects, and its design and construction directly impact project safety and efficiency. To ensure platform stability and operational safety, strict compliance with national regulations, technical standards, and safety specifications is required. The following are the key points: I. Regulatory and Standard Basis Elevator installation platforms must comply with the requirements of the "People's Republic of China Special Equipment Safety Law" and the "Special Equipment Safety Supervision Regulations". Installation units must possess corresponding qualifications and, prior to construction, complete installation notification procedures with the local market supervision and management department, submitting construction plans, personnel qualifications, safety measures, and other materials. Platform design must meet the relevant provisions of the "Elevator Installation Acceptance Code" (GB/T 10060-2023) and the "Safety Code for Elevator Construction and Installation" (GB 7588-2018) to ensure that structural strength, stability, and protective performance meet the required standards.   II. Te...

Elevators are core equipment used for vertical or large-inclination material conveying in modern industry, widely applied in fields such as mining, building materials, grain, chemical industry, ports, and construction. They drive hoppers or carrying devices through traction components (such as belts and chains) to realize continuous or intermittent conveying of materials from low to high positions. The following is a systematic introduction from the aspects of types, working principles, selection points, and safety maintenance:   I. Main Types and Characteristics 1. Bucket Elevator    - Applicable Materials: Powder, granular, and small materials (such as cement, grains, coal).    - Traction Methods: Divided into belt type (stable operation, suitable for normal temperature materials) and chain type (high temperature resistant, wear-resistant, suitable for large块状 materials).    - Discharging Methods: Centrifugal type (high-speed throwing, suitable for dry fine materials), gravity type (low-speed self-flowing, suitable for large块状 or viscous materials).    - Advantages: Large conveying capacity, high lifting height (up to 40 meters), compact structure and good se...

Material hoists are core equipment for vertical or steep-incline material conveying in industrial and construction fields, efficiently handling bulk materials (such as granules, powders, lumps) or piece goods through potential energy conversion. Their working principle relies on the coordinated cyclic operation of traction components and bearing components, widely used in construction, mining, warehousing and logistics, chemical production and other scenarios.   I. Core Types and Working Principles 1. Bucket Elevator      It uses buckets fixed on traction elements (endless chain, plate chain or rubber belt) to scoop up materials at the bottom, lift them to the top, and discharge through centrifugal force, gravity or a mixed method. Suitable for granular and powdery materials like grain, cement, and ore, with temperature resistance varying significantly by material: ordinary rubber belts withstand 60°C, heat-resistant rubber belts reach 120°C, and chain structures can bear high temperatures up to 250°C.   2. Plate Chain Elevator      Equipped with parallel plate chains and continuous material plate structures, it is specially designed for bulky,...

Window cleaning machines are professional equipment specifically designed for the cleaning and maintenance of external facades of high-rise and super high-rise buildings, and also include diversified products such as household automatic window cleaning robots. With the acceleration of urbanization and the growth in demand for smart homes, window cleaning machines continue to evolve in terms of safety, efficiency, and intelligence. This article will provide a detailed guide covering product types, market landscape, selection key points, and industry trends.   Product Types and Application Scenarios Window cleaning machines are mainly divided into two categories to meet different scenario requirements: - Professional Window Cleaning Machines: Applied in super high-rise buildings (such as office buildings, hotels, etc.), requiring integrated installation during the building design phase. Such equipment typically adopts rail-type, suspension-type, or telescopic arm systems, with extremely high requirements for safety and engineering adaptability. For example, some internationally advanced models can achieve a maximum outreach distance of 45 meters, covering complex facade structures, ensuring efficient operation and...

Recently, Rigid Machinery announced exciting developments: on the basis of its existing ISO9001 Quality Management System certification, following rigorous audits and evaluations by an authoritative certification body, Rigid has officially been awarded three additional certifications—ISO 14001 Environmental Management System, ISO 45001 Occupational Health and Safety Management System, and ISO 50001 Energy Management System.

After obtaining ISO 9001 Quality Management System certification in 2016, the company has established a mature mechanism featuring "full-process quality traceability and all-around risk control," laying a solid foundation for product and service quality. In res...

On February 19, 2025, RIGID welcomed its first international elevator installation team of the Year of the Snake for specialized hoist maintenance training at the company. During their visit, the overseas RIGID maintenance partners not only underwent a three-day professional training and assessment on hoist maintenance knowledge but also deepened their understanding of hoist applications through on-site visits, product experiences, and exchanges. Through on-site references, training, and friendly discussions, the international partners gained a clearer understanding of our company's innovation capabilities and product system, further strengthening the cooperation between both parties.   【Professional Empowerment: Theoretical Foundation】 To meet the in-depth needs of international clients, our company tailored a training course that progressed from the core structure disassembly of elevator installation hoists to fault diagnosis logic. Through 3D dynamic model demonstrations and international standard case analyses, complex mechanical principles were vividly presented. Trainees exclaimed, "Theory can be so lively!"   【Practical Exercises: Hands-On Guidance】 Under the guidance of tr...
