LEGO Technic Excavator

51H04NB9PYL LEGO Technic Excavator LEGO Technic Excavator Get digging with a functional Lego excavator. With the advanced Lego Technic line, skilled builders no longer need rely on their imaginations to drive their creations–Lego helps them build an engine. Peppered with mechanical principles and a dedication to authenticity, these sets don’t simply stack blocks, they use special pieces like beams, gears, pistons, pins, and pneumatic cylinders to build a functioning machine. Build the commanding Excavator from the ground up, complete with cool crawler tracks, rotating cab, and adjustable knobs to control the all-important arm and bucket. If you’re looking for a more compact workhorse, rebuild the excavator into a versatile tractor. This 286-piece set includes assembly instructions with detailed color diagrams for building both machines. Blend with other Lego Technic playsets (sold separately), or simply rearrange the pieces for a truly customized machine. –Heather Lyndon
Customer Review: Not the best design
I’m a big fan of Lego and Lego Technic. This is an otherwise interesting set that is beset by two problems: the track undercarriage is a bit flimsy and the worm-gear on the arm is too weak to drive both the middle and outer arm segments. With extended play, I expect the 8-tooth gear on the worm to fail. This set has been discontinued so prices vary wildly. You may find Lego’s more recent excavator, #8294, to be a better value proposition. The new model is larger and mitigates 8419′s shortcomings with new tracks and two linear actuators.
Customer Review: Good value, hours of fun
The instructions were a little less than clear with respect to using black or grey peices, but everything came together nicely. My color boo-boos resulted in a custom look. icon smile LEGO Technic Excavator

LEGO Technic Telehandler

51%2BzMYzqQGL LEGO Technic Telehandler LEGO Technic Telehandler Lift nearly anything with this heavy-duty Telescopic Handler! It’s loaded with realistic functions that you build right in, including a hydraulic actuator that raises and lowers the extending boom, front-end stabilizers, and working four-wheel steering. You can even add the Power Functions Motor Set (sold separately) to motorize the telescoping boom. Turn the knob on back to raise and lower the boom, then flip the switch the extend it. Tilt the front forklift to pick up the cargo pallet. Boom extends over 21″. Telescopic Handler measures 15″L x 15″H. Includes instructions for rebuilding into a rugged Log Loader. 1,182 pieces.
Customer Review: Lego Telescopic Handler
Excellent Lego offerings for 2008, and the 8295 Telescopic Handler does not disappoint. Just like the real machine, the boom raises uses the new unique Linear Actuators that seemed to have replaced the older pneumatic cylinders and air pumps. This is actually a good thing, without an air tank, it would take constant pumping to create enough air pressure to allow the cylinders to function, the actuators are ‘screw’ operated, you just turn a gear wheel on the back of the machine to actuate the cylinder to raise the boom, then using a slick clutch type setup on the side of the Telehandler you flip a switch to change the gearing to extending the boom. It would have been nice if the tilting of the forks on the end of the boom would have been operated on the machine, making it look more authentic, rather than the cheesy setup of having to turn a lever on the fork assembly itself, maybe 1 extra Linear Actuator on the end of the boom would have accomplished the task, but then the price tag might have hit $100 as well…either way it is a lot of fun, and actually fairly complex to assemble the Telehandler, even more so than the Flagship 2008 model, #8297 Off-Roader. It is advisable that you motorize the Telehandler with either #8293 Power Functions kit, or if you have an extra battery box, clutch gear and the small Power Functions motor, you can simply motorize the boom, which is actually quite cool to watch. You can motorize the #8294 Excavator as well with the same 3 parts, and it adds a lot of replay value to the sets.
