Road rollers are crucial equipment on asphalt pavement and various uneven road surface construction sites. Their operation directly affects pavement quality and service life. Below are some precautions for road roller operators during construction.

Bulldozers, as important construction machinery, are widely used in road construction, mining, earthmoving, and other fields. Their performance stability and service life directly affect construction efficiency and economic benefits. To ensure the long-term stable operation of bulldozers under complex working conditions, regular maintenance is crucial. This article will systematically analyze the key points of bulldozer maintenance from the perspective of professional technical engineers, providing comprehensive guidance for equipment managers.

Long-distance transportation of heavy construction machinery, especially bulldozers, is a high-risk, high-responsibility undertaking. Improper loading, unstable securing, and insufficient protective measures can lead to equipment damage, road hazards, transportation accidents, and even personal injury. As transportation safety officers, we must make thorough preparations beforehand to ensure that the bulldozer arrives at its destination "intact, safe, and on time." The following systematically analyzes the precautions to be taken in each stage, from loading preparation, protective measures, securing and reinforcing, monitoring and protection during transportation, to unloading and acceptance.

Spider cranes (also known as "spider hoists" or "mini spider cranes") are specially designed lifting equipment widely used in construction, maintenance, and special operations due to their compact size, strong adaptability, and excellent stability. This article, based on the structural characteristics of spider cranes, systematically introduces the key points of their maintenance and care from the perspective of professional maintenance technicians and equipment managers. It covers daily maintenance, periodic inspections, and upkeep, aiming to help machinery users ensure equipment safety, stable performance, and extend its service life.

Spider cranes (also known as spider hoists), as specially designed lifting equipment, are widely used in space-constrained and complex terrain environments due to their compact structure and high mobility, demonstrating irreplaceable value in such situations. Especially in urban construction, mining, ports, and work sites with challenging terrain, spider cranes offer unparalleled flexibility and adaptability compared to traditional cranes. However, despite their excellent performance in complex environments, operators must pay special attention to the following key aspects to ensure safe and efficient operation.

Concrete pump trucks are widely used in the construction industry, efficiently and quickly transporting concrete to various locations on the construction site. However, blockages in the pump truck pipelines are a common problem during prolonged use, causing concrete delivery interruptions, affecting construction progress, and potentially damaging the equipment. This article analyzes troubleshooting and handling methods for concrete pump truck pipeline blockages, helping engineers and maintenance personnel to resolve this issue efficiently and accurately.

Self-loading concrete mixer trucks integrate material loading, metering, mixing, transportation, and unloading functions. As a type of heavy machinery commonly used on construction sites, self-loading concrete mixer trucks are widely used in various construction projects due to their high efficiency and flexibility. Their core components include a hydraulic transmission system, mixing drum, loading mechanism, and electrical control system. To ensure the long-term stable operation of self-loading concrete mixer trucks, improve work efficiency, and extend equipment lifespan, regular maintenance and care are crucial. This highly integrated equipment plays a key role in engineering construction, but it also places higher demands on maintenance. This article will detail the maintenance and care of self-loading concrete mixer trucks from the perspective of a maintenance engineer.

A self-loading concrete mixer (or self-loading concrete mixer truck) is a mobile concrete production and transportation equipment that integrates loading, batching, mixing, transportation, and unloading functions. Compared to the traditional model that relies on external batching plants and transport vehicles plus on-site pumping/unloading, self-loading mixers are ideal for projects with dispersed construction sites, complex terrain, or high requirements for material supply rhythm due to their high mobility and on-demand batching and transportation capabilities.

Remote-controlled forklifts are an important part of modern warehousing and logistics equipment, widely used due to their flexibility and high efficiency. However, ensuring their safety and long-term stable operation is crucial during use and maintenance. This article introduces the safety operating procedures and maintenance of remote-controlled forklifts.

Remote control forklifts are a highly efficient piece of equipment in modern logistics and warehousing operations, widely used in confined spaces, densely stacked goods, and high-frequency loading and unloading operations. Compared to traditional forklifts, remote control forklifts offer advantages such as convenient operation, high safety, and strong flexibility, especially in situations requiring precise positioning and space saving. This article analyzes the usage methods and operational precautions of remote control forklifts to help users better master their correct use.
