Lifting Casters
Does anyone know the name of lifting casters? I'm looking for casters that lift a wooden box off the ground (50 lbs?), but ground themselves when a little pressure or weight is applied to the box. Thanks. |

Lifting Casters
The only type casters that I know about to accomplish what you want are
made for woodworking machines or work bench mobile bases. https://www.google.com/search?q=mobi...g&ved=0CDMQsAQ On 3/15/2015 7:21 AM, wrote: Does anyone know the name of lifting casters?

I think what you're looking for is called a "spring loaded caster". According to the description, spring loaded casters are designed to minimize shock so to protect the contents in the box. What I'm looking for casters for a box that wil ground itself when some weight is put on it. Without that added weight, the box will roll freely when pushed. |

Check for Library ladder hardware Thanks, I'm looking for something similar, only it's casters designed, for a box or crate. Under normal conditions, it's easy to push on the wheels. Then when weight is put on the box or whatever, it grounds itself and can't be pushed easily anymore. |

This "self stabilizing" is what going to cause him grief in his quest. What's a manufacturer to do? Offer a whole range of casters by weight? A number of them with an adjustable range? What's the demand likely to be vs one that can be lowered and locked manually like those used on woodworking machines as previously mentioned. Far better, I think, would be for OP to design his own rig. What immediately comes to mind is a set of casters, appropriate to the task, mounted outboard on slightly extended arms with a fulcrum close to the edge. The "Inner" arm would extend toward the center of the box and an adjustable spring/turnbuckle arrangement would adjust the casters to the weight of the box to the point where you could balance it and have it settle to the floor with the addition of a little weight. It would undoubtedly be clearer if I could post a drawing but you get the idea |

And further to that, I'm building a set of three steps about 20" high that I can use to get my butt back onto my wheelchair when I fall on the floor. The casters are for this step box ~ easy to pull around but grounded when I climb up on it. |

I think this is somewhat what you're going for, albeit less industrial. http://goo.gl/WrqpRs If you Google "rolling step stool" you'll a bunch of those designed for the kitchen. I'm not sure of the casters could be used for what you're making. But somewhere in between the kitchen and industrial ones has to be a caster you could use on which you could swap out the springs to work perfectly for your particular weight requirements. -- -MIKE- "Playing is not something I do at night, it's my function in life" --Elvin Jones (1927-2004) -- http://mikedrums.com ---remove "DOT" ^^^^ to reply |

What I want is casters that will hold something up so it can be pushed easily. Then when a little weight is put on it, it will ground itself on the floor. Don't know if this would work for you but I have a setup on my drill press that allows easy movement but grounding if I want it (turns out I never bother grounding it). Set up... 1. A base for the casters 2. 2 - lumber pieces of appropriate size near the ends of the base and hinged to it; the cross pieces need to be a bit greater than the caster height in one cross section dimension, a bit less in the other 3. Attach a lever to one end of each cross piece. I used 3/4" ply, maybe 2" x 12" In use, when the cross piece is "up" (thin dimension horizontal to the base),the casters touch the floor; when it is "down", the casters do not. -- dadiOH ____________________________ Winters getting colder?

I'll also be installing side handles to assist lifting myself up the steps. When I get it built I'll put a .jpg of it in ABPW. |

The ladder casters I came across in my cursory search were available in various weightings... some with 25 lb springs. If this is too strong of a spring perhaps the spring loaded casters as used on walkers would work... check a DME vendor for replacement casters. |

The casters are for this step box ~ easy to pull around but grounded when I climb up on it. OK, cancel my drill press thingy. I kinda think finding a ready made solution is going to be tough but how about this (I'm assuming you are making the steps)? 1. a piece of ply with standard casters 2. box with bottom, 2-4 bolts through bottom 3. attach #1 to #2 bolts but with compression springs between the two. 4. sides and/or front back of the box almost to the floor No weight on the box, it rolls easy; add weight and the springs compress allowing the box/step sides and/or front back to hit the floor. -- dadiOH ____________________________ Winters getting colder?

But the problem will be finding them to adjust to the weight you want. https://www.google.com/webhp?sourcei...sters&tbm=shop |

There are spring loaded for gates, spring for shock.. And spring for what you are looking for. Look for the weight you want. Each has a resting weight. Yup. I'll have to wait until I build my step box and then figure out how much it weighs. |

Yup. I'll have to wait until I build my step box and then figure out how much it weighs. One more thing. These are awesome little step ladders. I remember them well. I am sure they are pricey, but they might already have the hand hold that you need to shimmy up. http://cotterman.com/documents/ST124.pdf I would chose the aluminum over the steel. Not cheap. -- Jeff |

http://cotterman.com/documents/ST124.pdf I would chose the aluminum over the steel. Not cheap. There is one made exactly for my purpose. It's called a Para Ladder. http://www.paraladder.com/ I emailed the company, but didn't get a response. In any event, it would be cheaper for me to build one suited to me. That means thick shag rug on the steps, width to my specifications and deeper steps. I figure it can do double duty as ladder onto my bed when my cat gets too old to jump on the bed. And, I'll be using this project as an excuse to by myself a Festool Carvex jigsaw. Leon needs his commission. |

Well, one could easily adapt an auto 'air spring' adjustable suspension strut to lower a couple of wheels. Or, just mount a suitable auto helper spring/shock assembly with the right leverage on a pivoting pair of wheels (next to fixed legs). It'll look like it came from a truck undercarriage, of course. Strong design element! |
