Trends in the Transport Trailer Technician Trade
Technology
There is an increase in the use of telematics equipment for communication of system or component faults, monitoring status, modifying settings, and recording activities and location. A specific application for telematics technology is in refrigeration units, where settings can be monitored and changed from a distance. Other applications monitor trailer systems such as fuel systems, lighting, tire pressures and status of axles and wheel assemblies. Data obtained from telematics systems can better inform clients about trailer usage and maintenance.
Electric high-voltage refrigeration units are becoming more common in the marketplace. These units have a smaller physical footprint, reducing the load on the transport truck. Running these units on electricity is more cost-effective and produces fewer emissions than running on diesel fuel, particularly when units are parked and can be plugged into an electrical source. These high-voltage refrigeration units (up to 460 volts) require training and specialized equipment such as flash-protective gear, insulated tools and voltage meters.
New refrigerant technologies, such as nitrogen, are in place. These new refrigerants require different recovery techniques, new sealing and compressor technologies, and new material handling procedures.
Health and Safety
Conversions to new refrigerants bring new risks to technicians in terms of exposure to hazardous materials. They must adhere to Workplace Hazardous Materials Information System (WHMIS) and fire safety regulations to protect their health and surroundings.
Tools and Equipment
Beyond the regular tools of the trade, technicians are using more and more digital interfaces. Electronic devices such as smart phones, tablets and laptops are now essential tools.
Remote light and brake testers are available to connect to in-house maintenance systems, record component responses, maintain records for benchmarking and downloading equipment performance and meeting legislative requirements. Data transmission of diagnostic information is being recorded via Bluetooth and wireless technology.
Products/Materials
Transport trailer technicians must have current understanding of the design and structure of a trailer’s overall body makeup in order to maintain and repair according to industry standards and specifications.
Trailer materials are changing, with an increasing use of composite materials in cross-members and trailer structures. Galvanized steel is now standard for supports and under-frame components.
Specialized components and systems are being used in various trailer applications; some of these components include disc brakes, powered landing gear, self-steering and load-sensing lift axle systems, and tire inflation systems.
Environmental
There are new systems that capture and dispose of expired refrigeration gases in environmentally friendly ways. A greater variety of engine oils and washing fluids in use require awareness of their handling and disposal requirements. There is an increase in training and certification in environmental awareness in the trade.
Legislative and Regulatory
Safe Food for Canadians Act as well as Sanitary Food Transportation Act impose many requirements for food-hauling trailers; these ensure that the containers are sanitary and food grade, have adequate temperature control and that records are kept.
