Howdy, Before I begin, a bit of background to help y’all get into this review(?). Name’s Captain Contractor. I work as an abatement/demolition technician in America. Essentially, I have the licensing and training to remove asbestos, lead, and other hazardous building materials while also occasionally operating heavy equipment. A sect of machines that I use quite frequently is access equipment - boom lifts, cherry pickers, scissor lifts, etc. They are also one of my favorites, due to their ubiquitous nature and commonality across nearly all industries. Now, my interest in a LEGO version of them happened rather recently, when I came across a set of 3 designs on Rebrickable by user Brick Studs. https://rebrickable.com/mocs/MOC-86422/Brick Studs/boom-lift-bundle/#details This is a review + MOC extension on the first of their creations: a standard Genie S-40 boom lift (middle). Telescoping Boom Lifts Group by Captain Contractor, on Flickr Simple, iconic (in terms of the American construction industry, I do not have any experience regarding the European side of things), and overall a decent design. The colors are not a perfect match, however that is a minor gripe with no real effect on my feelings about the design. It has excellent SNOT techniques in use and a secondary jib arm connected to the boom. Genie S-40 Overview by Captain Contractor, on Flickr Pose-ability is rather limited, unfortunately, due to the weight of the basket design and the lack of counterweights in the superstructure. It is also rather fragile, with the SNOT panels and jib being held on by single stud connections. Genie S-40 SNOT by Captain Contractor, on Flickr Overall, it’s decent enough for a static display or as a transport load. Here we see it being used by a workman to repair the sign of a department store. Genie S-40 in use by Captain Contractor, on Flickr Onto the second lift. Essentially, I just produced a recolor of the Genie with a slightly different jib design and some simple decals. This one is a JLG 660SJ in the colors of Sunbelt Rentals. JLG 660SJ Overview by Captain Contractor, on Flickr As mentioned above, I made a more accurate version of the jib, giving it the functionality of also rotating the basket while still retaining the other movement functions. JLG 660SJ Side View by Captain Contractor, on Flickr As with the Genie, my JLG’s basket design is rather heavy and thus will droop if it isn’t supported. Simple, yet effective in its presentation. Here we see it giving an A/C unit removal crew access to the roof of a warehouse prior to demolition. JLG A/C Removal by Captain Contractor, on Flickr The final lift I have to show is a “Clapped-Out” Snorkel TB42. My inspiration for this one is the commonplace 80’s era access platform with a rusted exterior and 10k+ hours on the odometer (a lot for an occasionally driven machine); used by factory maintenance workers and kept alive through sheer will and constant repairs. Snorkel TB42 Overview by Captain Contractor, on Flickr Like the Sunbelt JLG, this one features simple decals and a pivoting basket. However, it lacks the additional jib arm seen on the other lifts. This is my personal favorite of the 3 self-propelled designs, due to the angular superstructure design and beefed-up chassis. Snorkel TB42 Side View by Captain Contractor, on Flickr For the last picture, I decided to just have it parked in the background, while the prior mentioned A/C removal crews maneuver the shells of the industrial cooling units for recycling (using a proper crew of operator, loadmaster, and machine spotter.) Snorkel TB42 Background by Captain Contractor, on Flickr Oh yeah, before I forget, here’s the safe working height for all three machines. They have the same amount of reach (unlike their IRL counterparts), at about 40 studs. That’s 12.5 inches or 31.75 centimeters. Boom Lifts Height Comparison by Captain Contractor, on Flickr Thanks for looking! Part 2 of this post will be on the spider lift and my custom NiftyLift re-design; with a 3rd part being relegated for the trailer-mounted cherry picker. C&C appreciated as always! Capt.

This is Lego's 42056 Porsche 911 GT3 RS set with some unique rallycross-inspired features I added making it the perfect sports car to drive in the snow. Features Suspension system raised to make the car about two studs higher Wheels and tires from the 42037 Formula Off-Roader Mudflaps LED light bar Front off-road lights Rear bash bars Optional snowplow that attaches to the front The lights are fake and don't turn on, and all of the other lime-colored pieces are from the 42037 set as well. I had a lot of fun making this. I just had to switch of the area of the springs to change the height for the rear without any pieces needed, but for the front, I had to remove the entire Porsche's body to make the lift there using a variety of pieces. Overall, I'm proud that a got the result I wanted, which was making the Porsche 911 GT3 RS higher (so it wouldn't bottom out) and equipping it with off-road features so I could have fun with this set in the winter. It does need to drive in snow only about an inch high so I could move it without getting stuck (and so the plow can move the snow too). I recommend to anyone who has the Porsche set to try these mods out for themselves this winter! Here's some more pictures of the car and a desktop wallpaper that I created wishing everyone at EuroBricks Happy Holidays! -
As part of our fully automated train layout (see more at our blog here: siouxnetontrack.wordpress.com), I have started to build a fully automated container warehouse. The warehouse should be able to store a large number of candy containers. I want to build four rows with shelves to store the containers, served by two robots that can store and retrieve the containers. The first thing I needed is to build the vertical lift for the stacker crane. I looked at other builds and found out that there are three possible mechanisms to create the vertical movement: Gears climbing a toothed bar (element 3743), a nice example can be found here: https://www.youtube.com/watch?v=GToA2tOVyHg Cables pulling the lift up, an example can be found here: https://www.youtube.com/watch?v=rCNwQVjXz60 Chain links, an example that uses the small elements 3711 can be found here: https://www.youtube.com/watch?v=fQIAAb8x8MI And as you may have guessed, I have tried something different. I use the worm gears (element 4716) to get the vertical movement, this is the first test setup: If you stack the elements 4716 on top of each other, they should be aligned correctly to create one, long worm gear. I just finished a first prototype of the stacker crane. The crane has two forks, in order to store or retrieve a container from either the left row or the right row. The lift can move up and down, the (horizontal) movement along the row needs to be build. One EV3 M motor is used to move the forks either to the left or to the right. It uses a color sensor to determine the middle position. One EV3 L motor is used for the vertical movement. A touch sensor is used to detect the bottom position. Watch the video to see a demo: More details will be added later. Enjoy watching and please let me know what you think. Hans -
Inspired by the Kinetic Device the "Lift", made by Jennifer Townley. I made it by Lego Parts. The pictures Side show A little detail And the most important, the video, the link is attached for backup. The mpd file was attached for anyone interested :) 999-Lego Kinetic Device with chains.zip -
Oops, @Milan can you close this topic, it double posted itself. Thanks! -
I am building a large ski resort with multiple fixed grip chairlifts and one detachable I am having problems with the fixed grip and I haven't done more than the frame on the detachable. the problems I am having with the fixed grip are simple, but I cannot figure out how to fix them. the chairs jam up a lot and the rope derails easily, both of which can damage the entire lift. on the detachable I need a small grip that can detach and reattach at the terminal, but flow easily over support and hold down sheaves. I am trying not to spent too much, but I want all of the lifts to work right. I am using power functions XL motors to power them.

So a few months ago I made a smaller version of Akiyuki's invisible lift, the problem was that I didn't have instructions for my version and it was not very reliable. I have now made a new version which is more reliable and uses less pieces. -
Based on 2013 Volvo FH16 6x4 its equiepted with ampliroll or hook lift system [media]http://www.youtube.com/watch?v=Bx8kawBn1Io[/media] Features: 1 M motor for steering 1 XL motor for drive 1 M motor and 1 linear actuator for the sliding/locking mechanism 2 Recievers 1 Standard battery pack 1 Flat bed 1 Wood log carrier 1 Open dump body? (i dont know how to call it) And openable doors Some more info: It uses 2 linear actuators for the jib but in order to make it work i needed to get more range so i used 2 tipper scissor style mechanisms to achive it. The sliding/locking mechanism uses a 12t to 24t because the jib flexes at the middle and its only got 2 fixed points this also means that it can only be powered when the jib is in the lower position something that real trucks use to prevent the jib from being accidentaly disengaged when its at the tipping position which could cause damage cause the body would fall down. The rear pendular suspension is achived by meshing a 12t to 20t gear so that they can rotate at the mesh (this is something i saw Zblj do in his videos) Things that can be improved: The rear chasis flexes cause it only uses 2 beams at the rear where the wheels are connected The linear actuators are too slow specially the sliding cause it uses a worm gear but i didnt have more room for other thing Since i build it i was told that in the real ones the 2 parts of the jib when they are in the hook position the jib has a contac point and then both of them move together so that the lenght of the point where it pivots to the point of the hook changes to have more power in the initial part of the lift http://www.brickshel...ry.cgi?f=527652

I don't have much space to use and the servo motor needs to be lifted from the bottom and up totaling 90° radius. The servo needs to be lifted with pneumatics. I've built this model in SR3D Builder to show you guys. It's not really many pieces so anyone could build it IRL and try to make out something. It should be easily recreateable from the pictures. I'm pretty clueless and I don't know of that many different mechanical solutions with 4 different liftarms or so, so I'm asking for help in hopes that someone would help me -
I made a little order picker and warehouse rack for my daily photo project. I took a forklift course last year and was told to always wear a safety harness when working at height. This could happen if you don't. Day 148 of 365: Order Picker by dr_spock_888, on Flickr
