HW actuators

[mattsdragons]

I'm trying to figure out a way to get the lifting scoop back on smidsy but don't know a actuator strong enough and powerful enough to use to power it? what would anyone recommend? or any other alternative

electic carjack?

Re: HW actuators

I know on Robot Wars the actuators from hospital beds were popular.

Re: HW actuators

commercial actuator are too flimsy for hw use, especially with smidsy as the lifter is on the front most commercial actuator will break when 100kg drives into it.

imo best thing to do would be to put in a small 20oz co2 bottle, tev reg, small 5/2 24v valve and a small pneumatic ram. that option would cost around, £100 cheaper than a new commercial actuator and a whole load better. you can put flow reducers on your valve then you can have your lifter fast as you like.

Re: HW actuators

alternatively you could get some m25 rod or soemthing and a powerful motor and make your own actuator :P

Re: HW actuators

thats another option aswell, could potentially go pneumatic, but I don't know how heavy or effective that would be when all i need to do is lift

Re: HW actuators

all it would do is lift. wouldn't be too heavy, probably bout the same as an actuator.

I have a 63mm bore lp ram in the garage, if I remember to put it in you can have it at Barnsley if you're there.

I did think about going the whole hog and putting a nice big full pressure flipper on the top of it. You'd have to put a lot of HDPE into it in place of the Hardox but it is very doable. The only reason we never developed it was cos of disturbed and the need to put the motors on the other side of the bulkheads (but that's been done hasn't it?

Re: HW actuators

wasn't it based on hydraulics originally?

Re: HW actuators

I honestly don't know, but as far as I know it was powered by a car seat actuator

It was originally powered by a car set actuator and then by a windscreen wiper motor, gearbox and mod 1 rack. Thats what the brackets at the front are for (if theyre still there)

The mod 1 rack was rebuilt and fixed and lasted one fight where it bent and broke the gearbox. I may still have it but I wouldn't recommend it at a cost of about £50 a fight :blush:

Re: HW actuators

The bracket is still there, though I'm cutting it out and keeping it as I have no use for it yet don't feel I should throw them out

Trying to think of a stronger way to bring the jaws back, but so they won't break after every fight

Re: HW actuators

In RCC2 we used an industrial actuator that was used to open the lids of silos.
