Basket-type bridge inspection vehicles Basket-type bridge inspection vehicles, also known as folding-arm bridge inspection vehicles (as shown below), are compact in structure, are less constrained by the bridge structure, and are flexible in operation. They can be detected under the bridge and can be raised to detect the upper part of the bridge. The structure can be wired/wirelessly operated, flexible and convenient, and sometimes it can also be used as a high-altitude operation vehicle, and the price is lower than a truss type bridge inspection vehicle. Its basic structure fully embodies the characteristics of the folding arm-mounted truck crane truck and aerial working vehicle.

The truss type bridge inspection vehicle truss type bridge inspection vehicle (as shown in the upper right corner) adopts a channel type working platform, which has good stability and large carrying capacity. In use, the inspection personnel can easily enter the platform from the deck or return to the deck, such as configuring elevators. It can greatly increase the depth of the bridge.
The product adopts two-stage retractable, two-stage revolving, and two-stage luffing mechanism to form a three-dimensional space and six-degree-of-freedom space motion system. An independent working platform can be formed under the bridge to facilitate staff walking. The stabilizer mechanism, self-propelled support castors and fixed counterweights are installed on the chassis to ensure the safety of operators. The product has the outstanding advantages of easy operation, no interruption of traffic, flexible operation, high work efficiency, easy operation, and high safety and reliability.

The development of foreign bridge detection vehicles The first bridge detection vehicles appeared in Europe and the United States, PALFINGER (Austria), HYDRA (USA), Aspen Aerials (Germany), MOOG (Germany), and other inspection vehicles for bridge detection. Nowadays, the equipment technology is very advanced, all adopts electronic hydraulic control, and is equipped with emergency devices, stabilizers, remote control devices and power generation equipment.

Domestic R&D Production Status As early as in the late 1980s and early 1990s, China was transformed and designed by the Department of Highway Planning and Design Institute of the Ministry of Communications at the QY-8 truck crane produced by the Beijing Crane Factory, and finally ended in failure. The development of several units also ended in failure. In recent years, some domestic large-scale construction machinery manufacturers have begun to work on the development of bridge inspection vehicles. Their products and performance can meet the standards of foreign equipment.

An electric motor is an electrical machine that converts electrical energy into mechanical energy . Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates in the reverse direction, converting mechanical energy into electrical energy.

Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless , may be of various phase (see single-phase , two -phase , or three-phase ), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use. The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches.

In certain applications, such as in regenerative braking with traction motors , electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.

Electric motors produce linear or rotary force ( torque ) intended to propel some external mechanism, such as a fan or an elevator. An electric motor is generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Magnetic solenoids produce significant mechanical force, but over an operating distance comparable to their size. Transducers such as loudspeakers and microphones convert between electrical current and mechanical force to reproduce signals such as speech. When compared with common internal combustion engines (ICEs), electric motors are lightweight , physically smaller, provide more power output, are mechanically simpler and cheaper to build, while providing instant and consistent torque at any speed, with more responsiveness, higher overall efficiency and lower heat generation. However, electric motors are not as convenient or common as ICEs in mobile applications (ie cars and buses) as they require a large and expensive battery, while ICEs require a relatively small fuel tank.
