More than month ago I've decided to begin building my biggest and most challenging alernative model so far. It will be forwarder (log loader) built out of set 8053 - Mobile Crane. The first issue was how to build complex crane with just one linear actuator and limited amount of gears. I've solved it by using worm gears instead of linear actuators and it works good. This is the first working prototype of rear part of forwarder: Then I've begun working on cab and this is the second version of it (you can aslo notice minor changes in crane): When I've showed it to my wife she told me that cab is too high and angular. What do you think about it? And last picture of forwarder ready to grab something: Few features and specifications: 4 axles with articulated steering working crane: rotation around vertical axis, lifting boom by wormgear, lifting stick by linear actuator, opening grapple by worm gear crane is operated from chassis (1 black axle connector and 2 red axle connectors) rotary seat in cab (not built yet) opening engine cover with fake engine (not built yet) target number of parts: 1000+ Few issues to solve: steering on smooth surfaces - wheels offer big resistance but it's OK on carpet overall design lack of useful parts Any comments and ideas for improvements are welcomed.
Hi, My main LEGO project of 2015: a KOMATSU forest layout with two forestry machines of KOMATSU forest. Both built in the Model Team style. The layout contains the KOMATSU 951 harvester, one of the newest and largest harvester of KOMATSU Forest, and the KOMATSU 895 forwarder, the largest forwarder of KOMATSU Forest.. Both built in a small scale and with several functions from the real machines. I've posted both a few months ago in the Technic forum.

I like to show you my new MOC: KOMATSU 895 “The gentle giant” At this moment, the KOMATSU 895 is the biggest forwarder of KOMATSU Forest. This moc took me three months to complete, because it was a challenging build to get all the details and functions in this 1:25 scale model. In real, the 895 has several ingenious functions to load and transport a lot of trunks. The following functions are in this scale model: - Wheel suspension -Telescopic boom -Shovel blade -74-AWI-4v diesel engine - Cabin with door - In the cabin, an operators seat which can turn 360 degrees - Ladder for enter te cabin - Adjustable LoadFlex - Adjustable Flexgate I've choose the 1:25 scale because I want to build a forest layout for this forwarder and a KOMATSU harvester. The 1:25 scale is a challenge for a detailed build, but I think I managed it Pictures: 01_KOMATSU_895 by Mathijs Bongers, on Flickr 02_KOMATSU_895 by Mathijs Bongers, on Flickr 03_KOMATSU_895 by Mathijs Bongers, on Flickr 08_KOMATSU_895_transporting_trunks_adjusted_LoadFlex by Mathijs Bongers, on Flickr Adjustable LoadFlex 09_KOMATSU_895 by Mathijs Bongers, on Flickr 10_KOMATSU_895_backside by Mathijs Bongers, on Flickr 12_KOMATSU_895_suitable_for_rugged_terrain by Mathijs Bongers, on Flickr The forwarder is suitable for rugged terrain. 20__KOMATSU_895_74-AWI-4V_diesel_engine by Mathijs Bongers, on Flickr 74-AWI-4V diesel engine Picture which shows all functions: 25_KOMATSU_895_overview_functions by Mathijs Bongers, on Flickr for more picture see my Flickr profile: https://www.flickr.c...157653524113986 Hope you like it
Hey all, While browsing youtube, I ran across this fantastic Komatsu 840 Forwarder built by Jonas/JH-Create: Objectives Authentic proportions Mechanical crane (not pneumatic) 100 % remote controlled Joystick controlled Strong enough to actully load and carry small logs in the forest Video at the end of the post. Functionality Forward / reverse with 8WD Articulated steering Rotating hitch – Independent tractor and trailer Locking mechanism for rotating hitch Working bogie axes Boom Slew Boom up/down Jib up/down Grapple open/close Grapple rotate Fake 4 cylinder engine Datasheet Propulsion: 2x PF XL motor connected to a common drive train Steering: Frame steering by two small linear actuators powered by a PF M motor Hitch lock mechanism: Micro motor Boom Slew: Large turntable turned by PF M moto Up/down: LA powered by PF M moto Jib up/down: LA powered by PF M motor [*]Grapple Open/close: Wormgear driven by PF M motor Rotate: Micro motor More info on his blog: http://www.jh-create...-forwarder.html He has some other nice mocs on his blog as well, but I really liked the forwarder.
