TRACTOR CAB

The commercial development of computer-based control systems for tractors and other agricultural implements has provided a platform that enables coded mapped information to be effectively transferred from a desktop computer to the tractor cab. Initially developed in conjunction with GPS field location for yieldmapping applications, this type of system is now being incorporated into tractors and specialised application vehicles (see Figure 4.6). These can be used to give access to the treatment map in the field, and hence control signals for the application system. Data transfer is commonly by smart cards with current systems, but it is likely that future developments will use radio/telephone connections to automate the data transfer process (Miller, 1999).

This seeks through regulations to protect agricultural workers and others working on the land. Regulations have been made to cover avoidance of accidents to children, circular saws, first aid, field and stationary machinery, threshers and bailers, power take-offs, ladders, lifting heavy weights and tractor cabs. 

ABS. Boats, caravans, trailers, cars, lorry and tractor cabs, vehicle body parts, luggage, refrigerator liners, tote boxes, materials handling containers, prams, machine covers and cases, baths, sinks, shower trays, surf boards, shelters (bus, workmen, telephone), wall panelling and external facing. 

Technical measures which are meant to protect people from harmful influences can also, as a side effect, mask indicators of hazards. Talamo (1982) has, e.g., pointed this out in his research on partially soundproofed tractor cabs. Decreasing the interior noise level in motor vehicles can be problematical, since drivers obviously rely on sounds related to driving and movement in their perception and estimates of speed (GUVU 7+8/82).

The molded article combines a multitude of features into one piece. In general, this single molded piece is the primary structural element of the inner roof of the tractor cab (Figure 1). It serves as the primary load-bearing element for the cab s interior and exterior. With more than a dozen features in one molded piece, maximum value with minimal assembly is achieved. Figures 2 and 3 identify the primary features incorporated in the molded roof.

Closed cab A vehicle used for pesticide application that is at least partially sealed from (closed to) the outside enviromnent, such as an air-conditioned tractor (Sielken, Ch. 8). 

There are many kinds of control valves. Mechanical valves must be accessible to the operator s hand electrically operated valves permit remote control of flow. For tractors or self-propelled sprayers with enclosed cabs, the remote-controlled valves permit all hoses carrying pesticides to be kept safely outside the cab. 

Table IV and T give results obtained for Inddan, one of the few materials having a significant number of observations from which to raw comparative conclusions. Data are given In y g chemloal/cm at each body location, along with application parameters useable for normalization of these numbers for comparative purposes. All materials were applied In mature fruit tree protection programs using alrblast sprayers of 500 gal/load capacity with 3 X low-volume nozzles. The only viable comparison to be made Is that between Farm % having no spray cabs on their tractors, and Farm T having spray cabs with charcoal air filters for their tractors. All persons monitored both mixed and applied their own materials, thus each fill-spray batch Is defined as a cycle (Cy). Since the subjects within an...

When the total Imldan exposure results are compared on normalized bases (/Hr, /Cy, /Lb), the obvious point Is that the use of a spray cab reduces the potential dermal exposure to about 1/3 or 1/4 of that shown for an open tractor. Similar results were obtained for Guthlon, where exposure ratios ranged from 5.7 to 3.1. 

There appeared to be little. If any, dermal exposure measured under normal application conditions when low pressure low boom sprsqrers (LPLB) were used on open tractors likewise for our measurements of a similar truck-mounted device In which the subject applicators worked In a cab with the windows down. In situations where the subjects were required to dismount In the field to clear nozzles or move booms or obstacles, the leg patches Invariably received material from the newly treated foliage. Chest patches were occasionally contaminated at this stage also. Both truck and tractor mounted sprayers showed similar exposure patterns for applicators. 

Applicator exposure with high pressure low boom sprayers was found to be even less than that recorded for LPLB devices. Tractors with and without spray oabs were tested, and there was seen no overriding advantage to the spray cab under normal conditions. Under severe conditions, like gustlng winds or line ruptures, a cab would logically afford more protection. However, winds should generally cause reconsideration of the days operations. 

For a truck tractor without mudflaps, the strips may be mounted outboard of the frame on brackets behind the rear axle or on brackets ahead of the rear axle and above the top of the rear tires at unladed vehicle height, or they may be mounted directly or indirectly to the back of the cab as close to the outer edges as practicable, above the top of the tires, and not more than 60 inches (1,525 mm) above the road surface at unladed vehicle... 

On a tmck tractor, clearance lamps mounted on the cab may be located to indicate the width of the cab, rather than the width of the vehicle.

The next credential that all interstate carriers (for-hire and private) must get is the Unified Carrier Registration, or UCR. This is done by filing a UCR application with the state the company is based in, unless that state is not a UCR state, and paying the appropriate fee. The fee will be based on the nmnber of power units (trucks and truck-tractors) the carrier operates. If the company is based in a non-UCR state, the company needs to check the UCR website and determine which neighboring state the carrier has to file the UCR with. There is no requirement to mark the vehicles or carry UCR paperwork in the cab. This is an electronic credential that is verified by officers druing roadside inspections.

The complexity of the vision for a truck tractor with connected semitrailer was shown in Fig. 1. The area of the ground to be seen is covered by different means of vision direct vision via window openings as well as indirect vision provided by different classes of indirect vision devices. Figure 1 also provides brief explanations of the different classes. The direct vision to the rear is often blocked by parts of the cab or by the superstructure carrying goods or people. Therefore indirect vision devices constitute the only means to provide the necessary fields of view. 

In Fig. 12 the interaction between direct (1) and indirect vision (3-6) from a tractor (7) is shown [90, p. 93]. The vision areas 3-6 represent the legally required fields of vision [84, par. 15.2.4.2]. However, the vehicle manufacturers cover larger vision areas of indirect vision to fulfill the customer expectations [27, Appendix D]. Despite this field coverage large areas that can be seen neither via direct nor via indirect vision occur nearby the cab. These blind spots (2) [17, p. 91], [71, p. 20],... 

Due to the optical link between eye point position, mirror surface and vision target [9, p. 298], [18, p. 30] the mirrors shall be attached to the vehicle in a way that they are visible from the driving position and display the relevant vision areas to the driver. This is associated with a further reduction of the available areas of body openings usable for direct vision. Thus, the mirrors lead to deterioration in direct vision ([18, p. 39] Fig. 12). [20, p. 42] can identify the exterior mirrors of a semitrailer tractor as the most important vision masking parts of the vehicle by a subject survey (Fig. 14). Within the study truck drivers were asked for the body parts or attachments, blocking the view from the vehicle cab. 

Instruct the driver to exit the cab, disconnect both air lines and lay them down on the frame. (Inform the driver that the emergency line is charged and to be careful when separating it from the trailer.) After the lines are disconnected, listen for and ensure that the air stops escaping from the emergency/supply line. Verify the tractors air pressure. 

Common controls. Tractor safety has improved greatly over the years. Rollover protective structures, seat belts, improved guarding, enclosed cabs, electronic controls, stability sensors, and climate control have all contributed to making tractor operations safer and more comfortable. 

ROPS work by limiting a rollover to 90 degrees and preventing the operator from being crushed under the weight of the tractor. ROPS work only if a seat belt keeps the operator in the cab as the tractor is rolling. 

Hydroxy functional acrylics are used in general industrial (GI) stoving rinishes in two distinct capacities. They are used to impart highly durable finishes for exterior components such as tractor sheet metal and cabs, fenders for earth moving equipment, or as one coat finishes in more wide ranging metal finishing such as office furniture, irons, microwave ovens, toasters, food mixers and blenders. 

Drivers of trailers are responsible for safely backing a trailer into the dock well. The trailer must be aligned properly so that it is spotted properly. At this point the operator may elect to leave the cab attached to the trailer or lower the landing wheels and spot the trailer on an approved pad. The tractor operator should properly place the wheel chocks in front of the trailer wheels to prevent any movement of the trailer. Each time a forklift enters and exits a trailer that has been spotted at a dock, the impact from this movement can easily cause the trailer to move forward. As often happens, the trailer could prematurely pull away from the dock. The lift truck could fall between the dock and truck or be left in the back of the moving trailer. Many trailer truck operators, however, are not accustomed to properly placing wheel chocks against trailer wheels. Lift truck operators erroneously assume that the wheels are chocked because that is the job of the trailer truck operator.
