Alternative to hydraulics In my dozer.

Hey any one got some ideas to replace hydraulics in my dozer ? I'm thinking I can get away with something other then hydraulics. Just looking for ideas. Let discuss it lol :cop:

This dozer uses dual 30mm stroke 50:1 L12-S actuators. Make sure to get the S series, as it takes an esc to operate, giving you infinite height adjustment.

The R series plugs directly into the rx and works exactly like a servo, as in if you put it on a stick ch, when the stick centers so does the actuator at mid travel.

Probably not the answer you were looking for but I'll put it out there just in case. How about doing an old-school cable dozer instead? No hydraulics needed. Only a winch which could even be a servo. Here's an example:

Hope this helps...

I've been thinking about these ...a really different build the dozer is kind of pricey to hack up...but..

I know i'm weird and like old stuff, but those cable dozers look really cool!
Good thing i'm not in the market for a dozer right now, that one looks great jerry. (Do it.)

The cable reeving on that top one might get a little confusing, but with that much compounding a servo winch should have plenty of power to work with if the blade is heavy enough to not float.

Well my dozer is already built and hydraulic, I was just looking for something different, the hydraulics are becoming a pain .

have you thought of trying the actuators they sell on ali express for the huina excavators? servos already attached to lead screws https://uk.banggood.com/Huina-Plastic-Strength-Main-Arm-Second-Arm-Bucket-Arm-Driving-Rod-With-Servo-For-550-RC-Excavator-RC-Car-Parts-p-1526341.html?gmcCountry=GB&currency=GBP&cur_warehouse=CN&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgcs&utm_content=lijing&utm_campaign=ssc-gbg-summersale-all&utm_design=152&ad_id=358675083520&gclid=EAIaIQobChMIoYXapqCi6gIVDe3tCh1Qig7yEAQYAiAB EgI6jfD_BwE

if the servos aren't strong enough you can take them off and attach gearhead motors
