Camera Crane
Seven Years in the Making
I've been doing this for seven years now. Wow SEVEN YEARS! I'm 27 now, have got a awesome missus, a lot to show for my seven years of being basically a company slut!
Bad Times
As I've previously noted there's been good and bad time's in my seven years in the Cranes. One of said bad times was one of the worst moment's in my life. I don't wish this upon anyone either in my seat or on the receiving end.
I was operating the crane at said time and we were working in the blind inside the building down a hole, say 3x3 metre's wide. Like any story it was a lovely summer's day blue sky to boot and not a breath of air. Picturesque day. I don't blame the dogman and neither does the poor chap who was on the receiving end but he did something that was a wee bit dodge, a short cut really, short part to that is that he hooked a load up wrong. Every now and then as an operator you get told to "be nice with that one" meaning the loads a little rough, so you do just that drive it like you were to be having sex for the first time, slow an safe ! Don't wanna be loosing ya load to early now a!!
But this time I didn't have the slightest clue as to what was going on because there was no call to be nice etc etc. We had to move 5 fire doors (about 100kg's each) from 1 hole to another. Simple enough task, hook the load up, bring it out of one hole and down into another. But as we brought the load (bear in mind all in the blind) down into the second hole the load caught on one end on a scaffold tube that just happen to be sticking out enough to grab our load, now because the chap who hooked to the load up took a short cut...he didn't put the pivot point of the load where it would under any normal lift would be, which is at the main block, where all the chains start from, instead the pivot point was about 200mm above the load then we had our 6m chain go up from there. So imagine a big door and then you pick it up from the exact middle, as soon as you put any sort of weight upwards or downwards at the end of the door it's going to want to flip/role over. And that's exactly what happened. As I was being told to come down on the hook (lower the load) I had maybe 800kg's on the hook at this point, (being the weight of the doors and my chains) the chains, my block, and the hoist rope all did a little dance an the radio went quiet, so as soon as my brain clicked a second or so I stopped the hook and noted that all I had on my weight gauge was 200 odd kgs - we lost the doors!
1st thing I did was get on the radio and ask the bro "what's going on I've lost all the weight." The reply was....silence....
I sat in the crane for about 2 more minutes before the reply came.....

Is craigslist.org awesome or what?! Do you love craigslist.org as much as I do?
I'm a HUGE craigslist fan! I've come across the greatest deals there! I bought a Cannon XL2 (2 years ago) for $2,500. I've sold guitars, amps, and mixers... I even bought a pair of roller blades for $10.00 (I used the wheels for a DIY camera crane and dolly system)
Um, yeah. you cant go wrong you can find everything from a car to someone to watch your kids...i love craigslist too!!!!!

Keep A Check With Wireless Security Cameras
The increase in the criminal activities is a growing concern for all. Whether we are leaving our house or staying inside, we just can't stop worrying about our family and belongings. Sometimes even the security guards cannot be trusted upon. The perpetrators can break in your office or house at any moment! With such a risk lingering around, most people nowadays are relying upon wireless security cameras which are often termed as CCTV or closed-circuit television. Some wireless cameras require a wired setup for power supply; it's basically the audio-video signal transmission that is done wirelessly. Nonetheless, some of them are literally wireless where even the power support is provided by pre-charged batteries. Advantages like flexibility, low installation charge, portability have made wireless security systems quite a popular and well-liked security device. You can even clean it easily and mount it wherever you want. Just make sure the battery is charged enough. But even if you miss out on that, there are certain varieties that are equipped with proper power backup systems. IP security cameras are mainly of two types namely- 1. Analog Wireless Cameras- With a transmission range of about 91 meters, these wireless security systems use radio frequencies to transmit audio/video signals. Walls, furniture, doors are likely to hinder the transmission. These are somewhat cheap products and each of the cameras has multiple receiver techniques. But the quality of image is relatively poor and the signals aren't quite secured. 2. Digital Wireless Cameras- The digital security cameras are by far the best ones. The signal is secured, the image and sound quality is fantastic, the cameras are multiple receivers enabled, a wide ranged transmission is provided, the receiver and camera share a two-way communication and furthermore, the digital signal catches even the slightest movement or blink. All these unparalleled benefits have prompted a relatively costly price but once you start using the system, you'll certainly feel contented. Signal transmission in digital IP security cameras is done via digital packets. In these emergency wireless setups the receiver and the camera communicates with the help of a frequency which is common to both the units. There are generally four available frequencies for the wireless camera. When a certain frequency is broadcasted, all the four camera units share it. The CCTVs usually have an in-built video receiver and transmitter separated from each other. When the camera is installed, it uses a specific frequency so as to transmit signals to receiver which is connected to the security monitor. Since wireless security cameras can be craned in any part of the house, you can have a lot of your requirements fulfilled other than just tracking intruders. You may need a surveillance system for keeping an eye on your baby and baby-sitter, for monitoring expensive belongings in your house, office or in museums, for watching the lobby or accounts office and in fact for numerous other requirements.
