It can work normally in places with power outages or no power supply, and a telescopic platform can be added.

When the platform length is not enough, it can be extended to the desired position, thereby improving work efficiency. It is an ideal equipment product for modern tall buildings and equipment and is essential for high-altitude safety and civilized production.

Boom Lifts

According to the arm extension method, it can be divided into two types: Telescopic Boom Lift & Articulated Boom Lift. It is mostly used in places with high height requirements such as shipyards. This type of machine has good safety and is easy to move, but the cost is high.

At present, there are four types of high-altitude work vehicles mainly used in the market: scissor fork type, straight arm type, curved arm type, and vehicle-mounted type. What are the suitable situations for each type of vehicle? Let me explain the characteristics of these models to everyone.

Application of the Scissor Lifts vs Boom Lifts

Scissor Lifts

The most widely used high-altitude work equipment, stable and safe, with a wide range of operations.

The scissor lift mechanical structure has a working height generally ranging from 6 meters to 14 meters. After lifting, the lifting platform has high stability, a wide working platform, and a high bearing capacity, which allows for a larger range of high-altitude operations and is suitable for multiple people to work simultaneously.

The power form can be selected according to different requirements (such as three-phase AC power supply, single-phase AC power supply, DC power supply, and internal combustion power supply, etc.), and equipped with manual hydraulic devices, it can continue to work in power outage or no power supply places and can be extended to the required position by adding a telescopic platform. When the platform length is insufficient, it can be extended to the desired position, thereby improving work efficiency.

Suitable for mobile high-altitude operations such as installation and maintenance of high-altitude equipment in various industries.

Telescopic Boom Lift

The homework results are simpler, the operation is convenient, the stability is good, the safety is reliable, and the height has an absolute advantage. It is a common equipment for ultra-high altitude operations.

Utilizing a sleeve-type drag chain structure to achieve high-altitude operations with telescopic boom lift, the platform can rotate 360 °, and both the working bucket and the platform can be operated. The boom is in any position, and the work platform can walk safely. The walking speed decreases as the lifting height increases.

Able to adapt to specific working environments, i.e. able to work in humid, highly corrosive, dusty, high temperature, and low temperature environments.

Articulated Boom Lift

The homework structure is simple, the operation is convenient, safe and reliable, and the appearance is beautiful. It is a high-altitude work equipment that optimizes safety and work efficiency.

Adopting a folding work arm (two-section arm, three section arm), with a working height of 15-45 meters, the lifting arm can rotate 360 ° and can be operated at both the turntable and the work platform. The boom is in any position, and the work platform can walk safely. The walking speed decreases as the lifting height increases. Equipped with upper and lower control consoles (ground control console and platform control console), and the upper and lower control consoles are switched using directional switches.

Widely suitable for installation, maintenance, and high-altitude operations in industries such as municipal engineering, electricity, street lighting, advertising, communication, photography, landscaping, transportation, docks, airports, ports, and large industrial and mining enterprises.

Additionally, there is an vehicle mounted high-altitude work platform.

Generally dominated by domestic brands, adopting a lightweight arm frame design, with a wide operating range, lightweight and flexible, and high operating efficiency. The supporting legs have a large span, good stability, and automatically detect the reaction force of the supporting legs. Any loosening of the supporting legs will stop the boarding work. When the chassis power system malfunctions, ensure that the platform can be lowered and the turning mechanism can be manually turned. The piston rod of the oil cylinder is protected by a protective sheath, and the head of the arm is equipped with a dust prevention device.

Municipal road engineering maintenance, street lamp maintenance, tree branch construction, billboard maintenance, etc.

With the above introduction, everyone can also better choose suitable products.

Purchasing Tips

With the development of social science and technology, whether it is architecture, civil engineering, or people’s daily lives, high-altitude work platforms are indispensable. Many businesses seize this opportunity and invest in building factories, and lifting machinery companies are standing like bamboo shoots in major industrial cities.

However, the lifting and lowering machinery industry is still booming and in short supply. From the side, it can be seen that the rapid development of society has driven the development of the entire industry and people’s needs. However, as buyers, how to choose good lifting machinery from the numerous company products has become an important topic today.

When choosing lifting machinery, one should not blindly choose it. Adequate market research and on-site inspections should be conducted to determine the size and credibility of the company. This is the most important and necessary thing. Many small-scale enterprises in the market cut corners to seek violence, which greatly reduces the quality of lifting products. Although they may sell them very cheaply, this type of machinery is not used for a long time and has a high degree of danger. Therefore, as a buyer, one should not indulge in a small discount on price and end up with greater regret.
Based on the information you have researched, choosing cost-effective lifting machinery should be based on its technical parameters, practicality, and versatility. There are usually many types of lifting machinery, including car-mounted elevators, boom lifts (Telescopic Boom Lift & Articulated Boom Lift), scissor lifts, etc., each with slightly different technical parameters and uses. However, many functions are similar. Therefore, as a customer, you should make a purposeful purchase, that is, what you want to do when buying a lifting machinery, and which type of lifting machinery can meet your needs and has multiple uses.
When buying a product, look at the accessories. The electronic control system, oil cylinder, pump station, sealing ring, battery, and other aspects are all very important.
The last point is that after the equipment arrives, during the unpacking acceptance, it is necessary to check whether the random technical information is complete, whether the random accessories, tools, and accessories are consistent with the list, whether the equipment and accessories are damaged or defective, and make a good record of the unpacking acceptance.

Working Principle

Hydraulic oil is formed by a vane pump to form a certain pressure, which enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the piston of the hydraulic cylinder to move upwards and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve. The pressure reading on the pressure gauge is observed.

The piston of the hydraulic cylinder moves downwards (i.e. the weight is lowered). Hydraulic oil enters the upper end of the hydraulic cylinder through an explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through a balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve.

To ensure stable descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed is not affected by heavy objects. The flow rate is adjusted by the throttle valve to control the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overloading or equipment failure.

Operating Standards TacMan

Professional operators who have undergone specialized training, passed exams, and hold certificates must be assigned to work.
Operators must follow the maintenance regulations of mechanical equipment and carry out various inspections and maintenance before starting the lifting platform. Before starting work, the working range of the platform vehicle should be checked, and obstacles that hinder the rotation and walking of the platform vehicle should be removed.
Support is an important preparatory work for the operation of high-altitude work platforms, and a flat ground should be selected. If the foundation is soft or uneven, it must be padded with sleepers before work can be carried out.
Generally, high-altitude work platforms should first lift the lower arm, then the middle arm, and finally the upper arm. During the rotation operation of the lifting platform, it is necessary to raise the lower arm to a certain height before turning. The rotation should be slow, and attention should be paid to whether the distance between the scissor arm and the platform to each equipment meets safety requirements.
Operators on the work platform should wear safety belts. When working in electrified areas, the vehicle body should be grounded according to regulations. The high-altitude operation of the lifting platform should be commanded by the person in charge, who should contact the lifting platform operator according to the signal specified in GB5082 standard. The signal emitted must be clear and accurate.
Before conducting platform operations, the person in charge of the work should provide technical and safety instructions to the operators, including: job content and requirements; Safety precautions and danger points; Personnel division of labor and scope of responsibility. The person in charge of the work should not only inspect the condition of the vehicle and the operators, but also be responsible for checking whether the terrain environment, takeoff and landing comply with the requirements of safety technical measures or the pre formulated work plan. If there are any discrepancies, corresponding measures should be formulated before starting work.

Matters Needing Attention

Any work carried out at a height of 2 meters (most domestic standards are 1.8 meters) or above should be considered as high-altitude operations. Any work that can be done in advance on the ground must be done on the ground to minimize high-altitude operations.
Personnel engaged in high-altitude work must be physically healthy. Those who suffer from mental illness, epilepsy, or have been identified by a physician as having hypertension, heart disease, or other diseases that are not suitable for high-altitude work are not allowed to participate in high-altitude work. It is prohibited to work at heights when it is found that staff members are drinking alcohol or feeling lethargic.
Personnel working on high-altitude work platforms must receive guidance on relevant equipment or be familiar with the equipment operation specifications and safety precautions for high-altitude work platform equipment in the “High Altitude Work Platform Operation Manual” before they can carry out high-altitude work.
When working on the dam crest, steep slopes, roofs, cliffs, towers, suspension bridges, and other dangerous edges, safety nets or protective railings should be installed on the side facing the air. Otherwise, workers must use safety belts.
Ice, snow, gravel, and soil on steep cliffs, slopes, or sidewalks must be regularly cleaned, and a 1-meter high railing must be installed on the outer side. Install 18 centimeter high side panels or soil ridges on the inner side of the railing to prevent falling objects from injuring people.
When working on scaffolding without scaffolding or without railings, if the height exceeds 1.5 meters, safety belts must be used or other reliable safety measures must be taken.
The seat belt should be inspected before use and a static load test should be conducted regularly (every 6 months). The test load is 225 kilograms and the test time is 5 minutes. After the test, check for any deformation, breakage, etc., and keep test records. Unqualified seat belts should be dealt with promptly.
The hook or rope of the seat belt should be hung on a sturdy and sturdy component or on a steel wire rope specifically designed for hanging seat belts. Prohibit hanging on moving or unstable objects.
All high-altitude work should use tool bags. Larger tools should be tied to sturdy components with ropes and should not be placed randomly to prevent accidents from falling from heights.
When working at heights, except for relevant personnel, no one is allowed to walk or stay below the workplace. Fences or other protective devices should be installed below the workplace to prevent falling objects from injuring people. If working on a grid like platform, wooden boards should be laid to prevent tools and equipment from falling off.
Tools and materials are not allowed to be thrown up and down. They should be securely tied with ropes and then lifted down or up to avoid injuring workers below or damaging scaffolding.
When working simultaneously at the upper and lower levels, a tight and sturdy protective partition, canopy or other isolation facilities must be erected in the middle, and workers must wear safety helmets.
When working outdoors at heights below minus ten degrees Celsius in winter, it is necessary to set up a heating rest area near the construction area, and the heating equipment should be managed by a dedicated person, paying attention to fire prevention.
In case of strong wind of level 6 or above, rainstorm, thunder, fog and other severe weather, outdoor work at heights shall be stopped.
It is prohibited to work on unstable structures (such as asbestos tile roofs). To prevent accidental login, warning signs should be hung at necessary locations of this structure.
