Trolleys are used in industrial, airports, hospitality, and other applications to move goods from one place to another. Vendors manufacture different types of trolleys depending on the needs of the target industry.

Tires are an integral part of an aircraft and are produced using various components such as synthetic rubber or natural rubber, with addition to carbon black and nylon tire cord fabric. The durability of aircraft tires depends on the aircraft models (endurance varies between 30-200 landings). However, by introduction of new-generation radial tires, the events of tire wear out are expected to decline.

Heliport lighting refers to a specialized lighting system designed to provide illumination and guidance for helicopter operations at heliports. It consists of various components, including elevated perimeter lights, approach lights, landing area lights, touchdown, lift-off area lights (TLOF), and wind indicator lights. These lights assist pilots in locating and safely navigating the heliport, especially during low-light conditions or at night. They help outline the heliport boundaries, guide the approach and landing phases, highlight the touchdown and lift-off areas, and provide information about wind direction and intensity.

Offshore supply vessel is known for providing support services such as the transportation of drilling equipment, manpower, and technical reinforcement, besides helping in terms of anchorage and tugging to offshore drilling rigs, pipe laying, and oil manufacturing platforms used in the production and exploration activities. The global offshore supply vessel market facilitates and supports the transportation and other activities at the oil and gas drilling and exploration sites.

The train collision avoidance system (TCAS) offers a warning or situational awareness that is specifically designed to prevent train collisions. Such systems are also extensively used in the mining and automotive sectors, apart from the railways sector, to avoid accidents caused by collisions. These are not specific to train mounting and can be deployed on railway tracks, crossings, and track-changing junctions.

The IFE (in-flight entertainment) system is introduced to enhance customer comfort and experience. IFE systems include in-flight connectivity, email, social media, on-demand video and audio, music libraries, online commerce, games, stored web content, smart card, battery, and information services. The technology includes moving map systems, audio and video entertainment, personal televisions, and in-flight movies. Furthermore, connectivity services include satellite and internal telephony, data communication, and Wi-Fi.

A commercial aircraft battery management system is a critical component in aviation that is responsible for managing and monitoring the health and performance of the batteries used in aircraft. These batteries serve various essential functions in commercial aircraft, such as providing backup power, emergency power for critical systems, and powering auxiliary equipment on the ground.

A construction dumper is defined as the medium used to transport loose materials such as sand, gravel, and aggregates for construction purposes. A construction dumper is equipped with an open bed box at the rear end of the dump truck. It also has a hydraulic piston, which lifts the hauler or trailer to dump the required material on the ground.

A fuel cell is a device that converts chemical energy to electrical energy in the presence of an electrolyte. It has two electrodes - an anode and a cathode, which facilitate the movement of positively and negatively charged ions to produce water and heat as by-products. Therefore, defense agencies are inclined toward fuel cell technology for their military aircraft (manned and unmanned).

A helicopter is a type of aircraft that uses rotating wings to fly. It can take off or land vertically, hover, and fly backward, forward, and laterally. These attributes allow its application in isolated or congested areas where vertical takeoff and landing (VTOL) cannot be performed by fixed-wing aircraft.
