Caterpillar 990
jorgeopesi posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Like I said in this topic Z-bar linkage help, I am building another wheel loader. This time is the Caterpillar 990 which is the biggest one I can build because the bigger ones like the 992, 993 or 994 have two cylinders for the bucket and it would be impossible keep the width in scale. It uses the Class tyres and in the beginning it had to be manual but I have so many room that I am thinking on a complete pneumatic RC loader. I hope you like the WIP process every advice is wellcome. I am trying wheels, should I have to buy the yellow ones?. -
Hi guys! Today I'm happy to show you my finished Cat ct660 truck. It have all-Wheel-drive chassis, mobular cab and Hood and it can be easily changed into a dump truck by removing the fifth Wheel to place a m motor. The truck use one servo motor for steering and two XL motor for propulsion. More pictures can be found here:https://www.flickr.com/photos/145703305@N06/albums It took me a while but the instructions are done and I will put the link soon! Link for the instructions:http://rebrickable.com/mocs/Technivor/caterpillar-ct660 Thanks for tking the time to read and any comments are welcome! -

Hello everyone: I am glad to share this project, the mining excavator, based on Cat 6090. Phisycal Configuration: The Lego Cat6090 is a motorized digger on tracked wheels, 2 XL motors provided enough torque. On the track frame is placed the main structure, and a heavy duty turntable allows good rotations, without fricctions. The turntable is rotated by means of 1 XL motor. The main structure contains: the XL motor for turntable, the air compressor, 4 servos for pneumatic valves and the controller. The design is ultra compact in order to meet the requierement of size/scale. The tracked whell is ultra rigid structure, designed to resist extreme load. The air compressor has 4 XL motor and 2 pneumatic pumps, in order to provide a constant air flow and high pressure, both pumps are de-phased 180° in order to reduce vibrations. 4 PF-servos open/close 2 way air valves, to command all pneumatic actuators. The boom has 2 large pneumatic actuator. Due to heavy height of the boom, 4 spring supply extra force during the elevation. 2 large pneumatics actuators push/pull the arm, those actuators are placed below the arm. 2 large penumatics actuators dedicate to rotate the bucket. 1 medium pneumatic actuator, open/close the bucket. Electrical configuration: Three 18650 batteries provide an average of 11.1 V, the compressor are suplied with 11.1 V, and the servos, lights and turntable motor are suplied with 9V. A BMS (Battery Managment System) manages the charge and the discharge durgin the operation. The tracked frame is steering by the use of 11.1 V, and as well is manage by the use of a BMS. On Board System (OBS): The name given to the controller. There are two systems, one for the main structure, and the secund is used to move the tracked well. The main controller, is a server TCP/IP protocol. The controller has a ESP8266 microcontroller with a TCP/IP stack, this controller is able to be programmed in arduino languaje (also micropython) - Teh ESP8266 is used as a sever, Motor driver: used to control the compressor The 4 PF servos are controlled by means of digital outputs, and the lights. ld293d, this is a H-bridge used to control the turntable motor. The second controller, is a ESP8266 as a client, and controls the speed of the tracks. Also, it has a BMS in order to regulates the charges/discharge of the batteries Accessories: 1) Josyticks: Two joysticks, with 4 dof (degrees of freedom) each of one plus a on/off button, are connected to the server module. 2) App: An application developmented under Android studio is used to visualizate the air pressure and electrical current, this app is WIP (work in progress). Conectivity: The comunication used is socket TCP/IP- Main features: maximun pressure reached: 52 psi (358 Kpa) Voltage bus: 11.1 V Compressor electrical consuption: 23 W Weight: 6 kg Length: 30 cm width: 20 cm height: 30 cm Here some pictures, during the construction and commissioning Note: my apologies for my primitive english -
This is the skid steer loader that I built last year. It was my second build after my long dark ages. I selected the Caterpillar 226B as a reference and selected the 62.4 wheels for this build. I realized only much later that the scale (especially the width) was very challenging. If I were to build this again, I would probably compromise and make it 2 studs wider. However, the biggest challenge on this build was something unexpected: the center of gravity. I started off with the power functions battery box. Due to the size of the model, the only place to put it was at the very back. With the first mockup, it was already clear, front wheels were never going to touch the ground. To fix this, I switched to the AAA battery box, as the AAA batteries weigh much less. This improved the balance, at least it sat still on all 4 wheels. However, it still did a wheelie every time it started to drive. My final card to play was replacing the two IR receivers with an Sbrick, to have less weight at the back. This improved things to the point where I thought that the whole model could work. It was still a wheelie monster, but there was hope. After that, I revisited each part of the model and redesigned to have as much weight as possible at the front. The bucket was brick built to have more weight at the front. The forward chassis had all empty spaces possible filled with liftarms. All empty holes were filled with pins, axles. I could see that I was getting there, but had to take some more extreme measures. In some places I used two thin liftarms instead of a normal liftarm. The cabin was designed to have smaller bricks at the front and so on... It was ridiculous, but in the end, it all helped, and the balance was fixed. Here are some more pictures of the finished model: The arms and the bucket work really well and quick enough. The drive is the weak point on this model, as it is only with M motors. Driving full speed is fine, no problems there. However, they have issues starting to drive with only part throttle, especially with 1.2v rechargable batteries. Due to the balance issue, I considered abandoning this project at several points along the way. However, I'm glad that I kept going, and I'm really happy about the result. Technical details Length: 30 cm Width: 13 cm Height: 17.5 cm Weight: 1.16 kg Power functions 2 x Power Functions M motor for skid steer drive PF L motor for arm lift PF L motor for bucket tilt PF AAA Battery Box Sbrick for control Here is the video with the model in action: -

Very unhappy with the 42028 tracked dozer, it was planned to make some modifications to let it look like the Iconic Caterpillar D11. But unfortunately every dimension of 42028 seems to be wrong and it became a moc. Because there are only two types of wide tracks available and the bigger ones need larger sprocket gears than available, i have chosen the old and small wide tracks. This results surprisingly in a nearly exact minifig scale of 1:30 -1:32. the fake engine looks even in 42028 much to large so i have skipped it and added a adjustable tooth at the back The Bogie suspension of the Caterpillar D11 is working in minifig scale too the shield in front of my D11 is mostly from 42028 because i have not had a better idea for it. for people who want build it is a LDD file available. Many thanks to Zblj for pulling the tracks on the gears! feel free to make critics and suggestions -
Still a lot of work to do but it works better than the old one. http://youtu.be/19fsEcU6KCA '>http://www.youtube.com/watch?v=qjj9hrUFYGc&list=UU0D6ectQCy7IVGlKE6rnqIQ

Hi! I just finished working on an alternative model of the 42114 set. I add large 107mm agricultural wheels to make the model look better but its possible to build it only with bricks from the set. Below are a few words about the model CAT 627K! Dimensions: Length 69cm, width 19cm, height 21cm Number of bricks: 1901 Photo of real machine for comparison: The idea to build a scraper was born almost a year ago. The project failed then, but I came back to it this year. I started the construction with a "boul" to make sure that the Volvo A60 - 42114 set has enough panels and liftarms. The next stage was the modification of the gearbox. I wanted the model to work with the official Control+ application profile. The scraper tractor has very little space for mechanics, so I split the gearbox in half and built a front axle into it. The real challenge was the bowl lifting mechanism. After a whole day of testing, I managed to build a linkage mechanism that imitates this function very well, even though it uses only one actuator. I used the second actuator to control the ejector. There is a second manually operated gearbox in the rear of the vehicle. In the first mode, the ejector moves while driving so you can empty the bowl automatically. In the second mode, the ejector is controlled manually. To change this, you just need to move the z16 sprocket. At the beginning, I was worried about whether I would have enough bricks to build all the details. So I was initially working on a scraper number 621K which does not have an engine at the back. However, it quickly turned out that I would be able to build all the details of the 627K model, such as the dummy engine or fuel tanks above the rear axle. I was very surprised that the available bricks managed to create a very nice looking cabin and front wheel mudguards.
