A maintenance inspection b. A safety and operational inspection The maintenance inspection is geared more to preventative maintenance and identifying those items requiring repairs that will prevent the crane from being in a like new condition or from operating correctly, such as oxidized or cracking paint, sheet metal damage, track pad wear, track roller wear, rubber tire wear, oil levels, oil changes, etc. The Equipment Superintendent or his representative usually performs this inspection. The safety and operational inspection, on the other hand is more concerned with identifying those items that will either stop a lift during the middle of an operation such as a worn sheave bearing that could freezes to it’s shaft or those items that could possibly lead to a component failure and an accident such as a hoist line with broken wires or a bent boom lacing. For example, this inspection would not be as concerned with tire wear because all lifts are required to take place on outriggers. However, excessive tire wear would be noted on the inspection report. Both inspections can be and sometimes are done by the same inspection party, but this procedure is geared to the safety and operational inspection and assumes that someone else will complete the maintenance inspection. Cranes should be visually inspected by “a qualified person”. A qualified person being someone who by virtue of his education and experience is knowledgeable about cranes, crane maintenance and rigging operations.

Typically, the source is a circuit breaker in the main electrical panel that has a rating large enough to handle the lights. It’s possible to mount the switches in the same or in different electrical boxes, but the latter case involves the extra task of running a circuit cable between the boxes. You maintain the continuity of the hot wire in the circuit cable by forming pigtails at the points where it connects to the switches.

You can mount the switches side-by-side in a double-gang electrical box or in different locations, each in a single-gang box.

The ground line (green or bare) should be attached to the ground screw on the switch (but is not shown). At the fixture, you connect the black “hot” coming in from the source to the new black wire running from the switch, and the red switch wire is connected to the black “hot input of the fixture.

This Air Filter System is a Nuclear, Biological, and Chemical NBC air filter that will enable you to create either a positive pressure safe room, fallout shelter, bomb shelter or a negative pressure isolation room. It will operate on regular v line power or will automatically switch to battery backup. An optional shown hand powered manual bellows can be ordered for use in a long term electrical outage.

It will handle up to 12 Adults. Output is cubic meters per hour. This Air Filter System can be mounted in a residential safe room with both backup systems in place: The air is drawn through the flex hose, into the bottom end bell, then through the filter bank in the middle and out the top end bell to overpressure the shelter or safe room. How does it work?

The filtration unit draws in unfiltered air from outside your shelter or safe room through an intake vent that can be located in a wall, window, or door. The air passes through a bank of up to 6 filters certified for the collection of nuclear, biological, and chemical NBC or CBRN toxins or natural contaminants and allergens such as dust or pollen at The NBC filtration system is comprised of Three separate filter media’s:


Electric Range Installation with a typical Volt electric power cord wiring system for 3-wire and 4-wire configurations. All new installations require the 4-wire circuit which has a separate insulated neutral wire and the separate ground wire along with the 2-hot wires. The Grounded Screw is attached to the metal frame of the electric range and is usually located under the neutral wire terminal location.

No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the power wire is plugged in.

Just because the stripes are in a certain order doesn’t mean the resistor has a direction! Resistors are the same forward and backwards, it doesnt matter which way they are used. Highlight the text below to see the answer Red – Red – Brown – Gold What is the value of this resistor? Highlight the text below to see the answer Ha! Trick question, it is not possible to put a resistor in ‘backwards’.

They work either way! Say hello to the LED! We’ve had some time with the LED already, but lets get to know her a little better.

In order to finish the choke, the attacker will sometimes vine their opponent’s legs or utilize a body triangle to reduce the chance of losing position. Non-title bouts consist of three rounds and title fights consist of five rounds. Sambo tournaments incorporate both grappling and striking.

No. Hook up the power wire first, then the ground wire. The ground wire is what acutually draws the power to the unit. As you will notice the power wont turn on if just the po wer wire is plugged in.

Though not all Chumash people ventured onto the Pacific, the group built large 30 meter , and well-designed plank canoes to view a contemporary Chumash reproduction visit http: They ventured off shore as far as the Channel Islands, and they fished for ocean fish. They also fished from the shore. Hooks were designed for specific fish species. Drawings of their circular hook raised questions in my mind about both the method of its construction and its hooking technique.

Its hook gap looked too narrow to effectively hook fish the same way modern hooks do.

Share on Facebook In electrical terms, “grounding” describes the safe directing of electricity into the earth. This is an important element of all home electrical appliances, including audio components. One of the most common problems that occurs when testing a newly set up home stereo system is a low-pitched hum that is heard at all times and with all functions. The usual explanation for this is that the receiver, which is the stereo’s “nerve center,” has not been properly grounded.

Once this problem is solved, not only should the hum disappear, but the operation of the receiver should be better and safer.

Check that first. If not, connect the ground from the panel to the fixture ground with a marette (just like the power wires) and twist the fixture ground around the green screw. While it isn’t critical to connect the ground wire from the fixture to the grounding screw on the mount, it’s a good idea.

Batteries provide power to the robot, and we sell several different batteries. Our motors are 12V or 24V. You can look at the motor pages to see what the current draw is for each motor. If you’re using small motors and don’t have the robot weighted down, the motors will not draw much juice so a small mAhr battery pack should be fine. However if you are going to load the robot up and run it in thick carpet or grass, or if you just want a long run time, then the larger AHr batteries would be a better choice.

Battery Wiring When wiring your batteries to your robot, there are concerns you must address. Namely, what output voltage you need and how you are going to charge the batteries. When using two 12V batteries you will need to wire them in parallel to power 12V motors and in series to power 24V motors. In a parallel setup, the positive red terminals are connected together and the negative terminals are connected to the chassis.

In a series setup, the negative terminal of Battery1 is connected to ground and the positive terminal is connected to the negative terminal of Battery2. The positive terminal of Battery2 is then connected to your robot. The way this works, is that the electricity from Battery1 travels through Battery2 and their voltage levels are added together.

In a parallel setup, both batteries will share the load of your system. Meaning your motor controller and motors will pull from both batteries equally.

This article takes you through the steps you need to hook a typical headphone amp up to the panel components. Switches There are so many types of switches out there that I cannot hope to cover everything. However, some basic concepts will help you to figure out the pinout on your switch. In a toggle or rocker switch, the pole lugs are usually along the center line of the switch. In a rotary switch, there are usually two rings of lugs and the pole lugs make up the center ring.

Throws are the number of unique paths through the switch per pole.

Sep 06,  · By hooking it up last to the engine block and not the battery. The small spark would be the same with older vehicles that have positive ground systems (which you would hook up the positive last). The only reason is to keep the spark away from the Status: Resolved.

If you have one of these, you may have wired the fan and light to separate switches. Now, you’d like to operate both of them from the same switch. The wires are already where you need them to be, so you don’t have to run new ones. That detail greatly simplifies the electrical procedure you’re about to undertake.

If the light and fan are separate fixtures, you’re going to have to run a short length of wire through the attic to connect them. This is the single most important part of any home wiring procedure. Even after switching off the breaker, it’s still a good idea to use a voltage tester to test the wire connections before you work on them. You’ll Need to Make Pigtails In electrical work, a pigtail is a collection of wires spliced together with a short length of wire.

The pigtail allows you to connect all the wires to a single terminal. The secret to making an effective one is to twist the wires together clockwise — not counterclockwise — before screwing on the cap. That way, the clockwise threads of the cap make the connection tighter when you screw it on. If you don’t know which one supplies power to each switch, turn the power back on and test the wires by connecting each to ground with your voltage tester.

The live circuit wires will give you a reading and the others won’t. Turn the breaker back off when you know which is which.

How to Install a Car Amp Installing car audio amplifiers is one of the trickiest things a newbie car audio installer can attempt. Car amp installation requires that all sorts of panels be removed and that various wires be run all over the car. Installing car audio amplifiers is a step by step process which I have outlined here. If you have any questions please contact me by clicking here. Please do not attempt a car amp installation if you are not comfortable with the process.

The first thing that workers on high-tension power wires do is establish an electrical connection between the wire and their Faraday cage clothing. This effectively brings their entire body up to that voltage and prevents current from flowing through their bodies. No current, no danger to the human.

Generation 1 cartoon continuity The Transformers cartoon Voice actor: Hook, who was evil, helped build Megatron. Bonecrusher would then reveal the Constructicons’ ability to combine by forming Devastator , who was blasted by Optimus Prime into lava. Heavy Metal War “Did you drop this? There are laws against littering. In the time between, he dismantled Optimus Prime, so it was a busy day for him.

City of Steel He later helped build the Transfixatron. Before a second Constructicon device could be used to destroy the powerless Autobots that the Transfixatron had stuck in vehicle mode , they were rescued, and Hook and the other Constructicons were defeated by their own Transfixatron. The Autobot Run “Heh, heh, heh! I’m going for the funny bone, Dad! Better get him back to the subway station,” The Constructicons then built a giant drill to tap into Earth’s core , although Hook had to reprimand Scavenger for almost messing it up.
