\n
In mechanical processing plants, steel structure workshops, and large storage plants, a large number of lifting trucks work in parallel along the same track. With multiple bridge-type vehicles shuttling back and forth, it is easy to run the risk of large vehicles colliding with each other. In the event of an impact, the light weight will cause deformation of the main beam, damage to the wheels, and gnawing on the track. The heavy weight will cause the crane to fall and the production line to be shut down for a long time, threatening the lives and safety of on-site personnel.<\/div>\n<\/div>\n
\n
Traditional workshops rely on visual avoidance by driving drivers and on-site command by ground personnel, and there are obvious shortcomings in manual supervision. Working continuously in three shifts for a long time, drivers are prone to visual fatigue; they encounter working conditions with large dust, dim light, and their line of sight is obscured by materials, which can easily form a supervision blind spot. Anti-collision protection device for lifting vehicles, also often referred to as bridge crane anti-collision device, crane anti-collision device, crane anti-collision system, is an active safety protection equipment developed for intensive operation of rail-type vehicles.<\/p>\n
\"Anti-collision<\/div>\n

Many buyers and equipment operation and maintenance personnel often consult: What is the role of anti-collision protection devices for lifting vehicles? What are the types of anti-collision protection devices for lifting vehicles? Where to go to view pictures of anti-collision protection devices for lifting vehicles. This article combines high-frequency search problems in the industry to introduce this set of protective equipment in an all-round way, which is convenient for factory selection and reference for the intelligent transformation of old vehicles.<\/p><\/div>\n

<\/div>\n<\/div>\n
\n

1. The role of anti-collision protection device for lifting vehicles<\/h2>\n<\/div>\n
\n
Many companies have a misunderstanding that installing buffers at both ends of the track can replace anti-collision protection devices for lifting vehicles. In fact, the buffer is passive protection, which can only reduce the impact of the impact, and cannot avoid the collision from the root cause. The anti-collision protection device for lifting vehicles belongs to an active early warning and protection system, and the two cannot replace each other.<\/div>\n<\/div>\n
\n
The anti-collision protection device of the lifting vehicle can continuously monitor the relative distance of two adjacent lifting vehicles in real time, and the system sets a multi-level safety zone. When the two vehicles enter the early warning range, the equipment activates sound and light alarms to remind the driver to slow down and avoid in time; if the vehicles continue to approach each other, the system automatically limits the speed of the cart; when the distance reaches the critical safety value, the opposite direction of travel is directly locked to prevent collisions. Accidents occur.<\/div>\n<\/div>\n
\n
In addition to realizing the anti-collision between the machine and the machine, the anti-collision protection device of the lifting vehicle can also monitor the distance between the vehicle and the column, wall, and end of the track of the plant to prevent the vehicle from colliding with the track and hitting the building. Long-term use can reduce the probability of damage to the main beam, wheels, and track, and reduce the cost of equipment overhaul. At the same time, equipped with effective anti-collision facilities, it is also a mandatory requirement for the annual inspection of special equipment and on-site inspection of safety supervision, to help enterprises implement the standardization of safe production.<\/div>\n

2. What are the anti-collision protection devices for lifting vehicles? Comparison of mainstream types<\/h2>\n<\/div>\n
\n
There are various types of anti-collision protection devices for lifting vehicles on the market. That is, the bridge crane anti-collision devices and crane anti-collision devices that everyone searches for. According to the principle of ranging and detection, they can be divided into three mainstream types, which are adapted to different workshop working conditions.<\/div>\n<\/div>\n
\n
1. Infrared anti-collision protection device for lifting and driving<\/strong><\/p>\n
<\/div>\n

The infrared anti-collision device has a simple structure, easy installation, low procurement cost, and relies on infrared photoelectric signals to realize mutual identification of equipment. It is suitable for ordinary machining workshops with less dust and stable lighting conditions. The short board is very obvious. When encountering heavy dust, water vapor, and direct sunlight, the optical path is easily obscured, and the signal is unstable, false alarms, or missed inspections occur.<\/p><\/div>\n<\/div>\n

\n
2. Anti-collision device for laser crane<\/strong><\/p>\n
<\/div>\n

The laser anti-collision ranging accuracy is high, the response speed is fast, and the safety protection distance can be flexibly customized. It is suitable for large-span factories and densely arranged factories with multiple lifting vehicles. When using, it is necessary to pay attention to the hoisting material and not to block the laser probe for a long time to avoid monitoring failure in a short period of time. Daily maintenance needs to keep the lens clean.<\/p><\/div>\n<\/div>\n

\n
3. Microwave radar crane anti-collision system<\/strong><\/p>\n
<\/div>\n

The radar-type anti-collision system has the best anti-interference ability, is not affected by dust, fog, and light intensity in the workshop, and has stronger penetration. In harsh working conditions with high temperature and dust such as metallurgical workshops and foundries, microwave radar crane anti-collision systems are preferred. The stable operation of the equipment and the low failure rate are the mainstream choices for the transformation of large-scale factories.<\/p><\/div>\n<\/div>\n

\n
Distinguished from the control function, it can also be divided into simple alarm type and electronic control linkage type. The simple model only provides sound and light reminders; the linkage anti-collision system can be directly connected to the original electrical circuit of the vehicle to achieve automatic deceleration and forced shutdown, with a higher level of safety protection. When you look for pictures of anti-collision protection devices for lifting vehicles, you can also visually see the differences in the appearance of different types of probes and on-site installation methods.<\/div>\n
<\/div>\n<\/div>\n
\n

3. Key points for installation and commissioning of anti-collision protection device for lifting vehicles<\/h2>\n<\/div>\n
\n
After installing anti-collision devices for bridge cranes in many factories, the protection effect is poor, mostly due to unreasonable installation location and improper parameter debugging. The sensor is prioritized to be installed in the center position of the beams at both ends of the trolley, to ensure that the two driving probes can send and receive signals in the forward direction.<\/div>\n<\/div>\n
\n
The installation height avoids the shaded areas of spreaders, cables, and stacked materials, and the lines are shielded and protected to stay away from strong electromagnetic equipment such as frequency converters to reduce signal interference. In the formal commissioning stage, combined with the actual operating space of the workshop, the early warning distance, deceleration distance, and braking distance should be reasonably set, and the unified parameters should not be directly applied.<\/div>\n<\/div>\n
\n
The transformation of old lifting vehicles does not require large-scale changes to the original electronic control lines. Most of the anti-collision protection devices for lifting vehicles use passive contact access, and the construction cycle is short, so as not to affect the continuous production of the workshop as much as possible. After all the installation is completed, it is necessary to simulate the driving conditions of the two vehicles facing each other multiple times, complete the entire process of alarm, deceleration, and shutdown, and confirm that the function is stable before it can be officially put into hoisting operations.<\/div>\n
<\/div>\n<\/div>\n
\n

Fourth, distinguish the concept: anti-collision device for lifting vehicles and safety protection device for truck cranes<\/h2>\n<\/div>\n
\n
When many users search for keywords, they will simultaneously search for the safety protection device of the truck crane and the name, function and location of the safety protection device of the truck crane. Make a distinction here to avoid confusion in the selection.<\/div>\n<\/div>\n
\n
Anti-collision protection devices for lifting vehicles are used in indoor rail-type bridge-type vehicles and gantry-type vehicles; truck cranes are mobile mobile lifting equipment, and supporting safety protection devices are mainly torque limiters, anemometers, and outrigger pressure monitoring equipment. Truck cranes do not have a fixed operating track, and generally do not carry a special crane anti-collision system for the track. The usage scenarios and hardware structures of the two are completely different, and the procurement options cannot be mixed.<\/div>\n<\/div>\n
\n
Broadly speaking, the anti-collision protection device for lifting vehicles belongs to one of the major categories of crane protection devices. Crane protection devices include a series of safety accessories such as overload limiters, travel limits, buffers, and anti-collision equipment. Enterprises need to integrate a complete set of protection systems based on the working conditions of their own equipment.<\/div>\n

5. The actual value of installing anti-collision protection devices for lifting vehicles<\/h2>\n<\/div>\n
\n
From the perspective of safe production, there is great uncertainty in relying solely on the driver's naked eye to judge the spacing. Long-term operation in three-shift vehicles is prone to fatigue. The anti-collision protection device of the lifting vehicle is on duty continuously for 7\u00d724 hours, regardless of the status of personnel and ambient light, and continuously resolves the collision risk of multi-machine parallel operations to protect the safety of personnel and equipment.<\/div>\n<\/div>\n
\n
From the perspective of operation and maintenance costs, once the two carriages collide, the maintenance costs of main beam correction, track repair, and wheel replacement are high, and the production line will be shut down. The deployment of anti-collision devices for bridge cranes can greatly reduce the probability of collision failure, extend the overall service life of lifting vehicles, and save long-term maintenance expenses.<\/div>\n<\/div>\n
\n
From the perspective of compliance management, the current safety supervision standards of industrial and mining enterprises continue to tighten, and multiple vehicles are operating intensively in factories, and active anti-collision protection facilities are the focus of safety standardization assessment. Equipped with qualified and effective anti-collision protection devices for lifting vehicles, it can successfully pass regular inspections of special equipment and unannounced inspections by safety supervision, and avoid downtime rectification and administrative penalties.<\/div>\n
<\/div>\n<\/div>\n
\n

6. Summary<\/h2>\n<\/div>\n
\n
Anti-collision protection device for lifting vehicles, also known as anti-collision device for bridge cranes, anti-collision device for cranes, and anti-collision system for cranes, is an active safety facility necessary for intensive operation scenarios of orbital lifting vehicles. When selecting models for enterprises, they should select the appropriate types based on the dust, light and number of vehicles in the workshop, standardize the installation and commissioning, and give full play to the anti-collision protection capabilities.<\/div>\n<\/div>\n
\n
It should be noted that the anti-collision protection device for lifting vehicles is a safety auxiliary equipment and cannot completely replace the standardized operation. Enterprises must continue to carry out safety training for driving operators to prevent violations such as savage driving and close-range risky driving. Hardware protection and standardized on-site management, a two-pronged approach, comprehensively avoid the hidden dangers of lifting and driving collisions, and build a stable and reliable workshop lifting operation safety system.<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
