Dump trucks come in various sizes, ranging from small ones used for residential construction projects to large ones used in mining operations. They are typically equipped with powerful engines and robust suspension systems to handle heavy loads and rough terrains.

Safety features such as rear-view cameras, backup alarms, and advanced braking systems are often incorporated into dump trucks to ensure the safety of both the operator and those working around the vehicle.
Overall, dump trucks play a crucial role in the transportation of materials, making them an essential component of many industries that rely on the efficient movement of bulk materials.
Advantages and disadvantages of sidewalk gates
Three roller gates are also called three lever gates, three stick gates, three roller gates, roller gates, and roller gates. The blocking body (brake lever) is composed of 3 metal rods in a space triangle. Generally, a hollow closed stainless steel tube is used. Three-roller brake is a type of gate that appeared early and has matured to the present. However, it has been gradually replaced by subsequent swing gates and wing gates. From the movement control mode, it is divided into mechanical, semi-automatic and fully automatic. Formally divided into vertical and bridge type, the vertical three-roller gate is smaller and easier to install; the bridge-type three-roller gate has a longer passage and higher security.
Three roller brake advantages
1. It is very effective to achieve a single single-pass, that is, only one person can pass at a time, and the safety and reliability are relatively high.
2. Low cost.
3. Strong waterproof and dustproof ability, strong adaptability to the environment, suitable for outdoor and indoor.
Disadvantages of three roller brakes
1. The aisle width (refers to the width that allows pedestrians to pass) is relatively small, generally around 500mm.
2. The traffic speed is relatively slow.
3. Restricted by the shape of the blocking body, it is not suitable for passengers with luggage.
4, the appearance of plasticity is not strong, most styles lack of aesthetics.
5. Mechanical and semi-automatic three-roller brakes have mechanical collisions during the operation of the levers, and the noise is relatively large. Full-automatic three-roller brakes do not have this problem.
Three roller brake application
It is suitable for the occasions where ordinary pedestrians and pedestrian flows are not very large or the pedestrians do not care about it, and some outdoor environments with harsh environments.
Swing gates are generally referred to as flapping doors in the rail transit industry. The shape of the blocking body (swing pendulum) is a plane with a certain area, perpendicular to the ground, and blocking and release are achieved by rotating and swinging. The material of the blocking body is usually stainless steel, plexiglass, and tempered glass. Some also use metal plates to cover special flexible materials (to reduce the impact of pedestrians). From the movement control mode, it is divided into mechanical and automatic. It is morphologically divided into vertical, bridge, and cylindrical. The vertical and cylindrical are small in size and easy to install, but the passage length is short and the function of the pedestrian detection module is limited; the bridge swing gate has a longer passage and pedestrian detection. The module has stronger functions and higher security.
Advantages of swing gate
1. The wide range of aisles is the largest among all brakes, generally between 550mm-1000mm. Some high-end products can achieve 1500mm, which is more suitable for pedestrians or bicycles carrying luggage and parcels. It can also be used for mobility inconvenience. Exclusive channel.
2. Compared with the three-roller gate, the bridge swing gate has added a pedestrian detection module, which can effectively detect the passing target and has a strong anti-trailing ability.
3. The plasticity of the appearance form is strong among all the gates, the material of the blocking body is rich, the shape of the box is also diversified, and it is easy to design a very beautiful shape, so it is often used in high-end occasions such as office buildings, intelligent buildings, and clubs.
4. There is no mechanical collision during the operation of the pendulum, and the noise is relatively small.
Disadvantages of swing brake
1. The cost is high, especially for some special customized models, such as increasing the channel width and using the special material of the pendulum, the technical difficulty will increase a lot accordingly.
2. Some models have insufficient water and dust resistance, and are only suitable for indoor use. The ability to adapt to the environment is not as strong as a three-roller brake.
3. Due to the limitation of the shape of the blocking body, the impact resistance of the swing gate is lower than that of the three-roller gate. Pedestrians and the movement are easily damaged if the pedestrians pass illegally and quickly.
4. If the manufacturer's design is not good, the reliability of the product will be greatly reduced, and the anti-crash and anti-collision ability to avoid personal injury will be reduced.
Swing brake applications
It is suitable for occasions with relatively large requirements for aisle width, including occasions where there are many pedestrians or bicycles carrying luggage and parcels, and special passages for people with reduced mobility. It is also suitable for occasions with high requirements on aesthetics.
The wing gate is generally called a scissor gate in the rail transit industry, and is also called a speed-through gate in many places abroad. Its blocking body (gate wing) is generally a fan-shaped plane, perpendicular to the ground, and is blocked and released by telescopic movement. The material of the blocking body is usually plexiglass and tempered glass, and some also use metal plates to cover special flexible materials (to reduce the impact of pedestrians). The movement control method is only fully automatic. The form is only bridge-type, and the pedestrian detection module is more powerful.
Wing brake advantages
1. The passing speed is fast among all the gates.
2. The width of the channel is between the three roller gates and the swing gate, generally between 550mm-900mm.
3. The appearance is more beautiful, and the material of the brake wing is richer.
4. In emergency situations, the brake wing will quickly retract into the box, which can easily form an obstacle-free passage, improve the speed of passage, and facilitate pedestrian evacuation.
Wing brake disadvantages
1. The control method is more complicated and the cost is higher.
2. Insufficient waterproof and dustproof ability.
3. The appearance is relatively single and the plasticity is not strong.
4. Due to the restriction of the shape of the blocking body, the impact resistance of the wing gate is lower than that of the three-roller gate. Pedestrians illegally rushing through the gate are likely to damage the wing and the movement.
5. The technical requirements of the manufacturer are relatively high. If the design is not good, the reliability of the product will be greatly reduced, and the anti-clamping ability to avoid personal injury will be greatly reduced.
Wing brake applications
It is suitable for indoor occasions with a large number of people, such as the ticket gates of subways and railway stations. It is also suitable for occasions with high requirements on aesthetics.
