Off Road Equipment Accessories and Attachments Part A Flashcards
Two types of protective structures can be mounted on an off road machine to protect the operator from Harm. Identify these two types of structures.
a. Falling object protective structure
b. Roll over protective structure
Protective screens and guards may be mounted on the basic protective structure. These components must be mounted so that maximum operator protection exists while operator visibility is restricted as little as possible.
True
When you repair a protective structure you should follow the instructions and recommendations provided by the particular manufacturer.
True
Identify three reasons why fire suppression equipment should be installed on off road equipment.
a. The cost of equipment is very high.
b. The cost of equipment downtime and lost production is very high.
c. Huge quantities of fuel, oil and lubricants are carried on large off road machines.
Identify the two different types of heat detection sensors that could be used on a fire suppression system that has an automatic control center.
a. Spot sensors detect high temperatures at specific locations.
b. Linear detection wire detects high temperature whenever the wire is installed.
Dry chemical powder and liquid chemical solutions can both be used in a fire suppression system.
True
A fire suppression system can pose some danger to an operator or personnel in the vicinity when the system is activated. Identify the three system components that could affect human life.
a. The chemical agents
b. The compressed gas.
c. High system pressure that drives the gas from the nozzles.
The following are examples of ground engaging tools.
a. cutting edges.
b. corner bits.
c. ripper points.
d. scarifier points
e. all of the above.
e. all of the above.
A scarifier is able to penetrate to great depths in the ground.
False. A ripper is.
Identify the different types of optional attachments mentioned in this module that could be mounted on a motor grader to improve productivity in the winter.
A snow wing, a V plow, a scarifying cutting edge and a scarifier.
Protective structures must be mounted on the machine so that impact forces are transmitted through the mounting arrangement to the main frame.
True
Lights and other accessories can be mounted on a protective structure. Holes for the mounting brackets should be drilled through the structural member to provide the maximum support for the lights and accessories.
False. Members that will not affect structural integrity.
What safety precaution should you follow when you remove and replace a protective structure?
Always use proper lifting equipment that can handle the weight of the structure. Use slings or beams to balance the load. Keep other workers clear of the work area.
Some fire supression systems are manually activated. Other fire suppression systems are manually and/pr automatically activated.
True
The only gas used to signal, trigger, and pressurize fire suppression systems is carbon dioxide.
False. Nitrogen is also used.
