Application guide — sizing, models and mounting advice from the manufacturer
A mobile tower has to be plumb to be safe, and factory floors are rarely level. Leveling casters give you a caster wheel to move the tower and a threaded pad to take out the slope and stand the tower solid — without a stack of packers under one leg.
Drainage falls, loading bays and old concrete all slope. Independent threaded pads let you bring the tower back to plumb, which packers and timber offcuts cannot do repeatably.
The tower rolls on the wheels, then stands on fixed pads. Nothing creeps while someone is working at height.
The load on a tower caster is not the tower alone — it is the tower, the platform, the people and the tools. We will help you size for the worst case rather than the empty tower.
Small scaffold wheels jam on every joint and stop. A larger diameter wheel rolls straight over them, which means fewer people pushing.
Add up everything the casters are actually carrying: tower 150–250 kg, two people 160 kg, tools and materials 50–100 kg — call it 450 kg. Over four casters that is 113 kg each, and with a generous margin for uneven loading and wind you want at least 250 kg per caster, which is DC-60F. In practice most customers specify DC-100F at 750 kg per caster because the margin costs little and the bed is much more forgiving. If the tower has to be levelled on a steep floor, check the pad's adjustment travel before you order.
Important: casters level a tower over small floor variations and let it be moved. They are not a substitute for stabilisers or outriggers. Always follow the tower manufacturer's instructions and your local working-at-height regulations, and never move a tower with anyone on it.
| Model | Per caster | Mounting | Why it suits |
|---|---|---|---|
| DC-60F | 250 kg (550 lb) | Top plate | Light towers on reasonably level floors |
| DC-100F | 750 kg (1,655 lb) | Top plate | The usual choice — generous margin and a large wheel for joints and thresholds |
| DC-100S | 750 kg (1,655 lb) | Threaded stem M16 | Tower legs with an existing threaded socket, no drilling |
| DC-150F | 1,500 kg (3,305 lb) | Top plate | Heavy towers and multi-section platforms; 92 mm wheel |
| DCRA-75 | 600 kg (1,320 lb) | Top plate with brake | Where regulations call for a braked wheel on every leg as well as levelling |
Nylon for factory floors and yards: it rolls over joints, resists grit and does not pick up debris. Polyurethane where the tower runs on a finished floor and noise matters. If the tower has to cross gravel or broken ground, none of the small caster classes are the right answer — tell us the surface and we will say so rather than sell you the wrong product.
Yes, and they are common on mobile access towers. They let you roll the tower into position and then wind each pad down to take out floor slope and stand the tower solid. They do not replace stabilisers or outriggers, and you must still follow the tower manufacturer's rules.
Add the tower, the platform, the people and the tools together, divide by the number of casters, then add a generous margin. A typical two-person tower works out around 250 kg per caster as a minimum, and many customers specify 750 kg casters for the extra margin and the larger wheel.
A braking caster locks the wheel so the tower cannot roll, but it does not lift the wheel off the floor. A leveling caster winds a pad down until the wheel leaves the floor, so the tower stands on a fixed foot. Some applications need both — we can supply braked models from our Japanese series alongside leveling models.
We supply CE declarations, our ISO 9001 certificate and RoHS statements, plus load test data. Tell us what your site or client requires and we will confirm what we can provide before you order.
Tell us the equipment weight, how many casters you plan to fit, the mounting you have and the floor it runs on, and we will come back with a model, a price and a lead time. Need the geometry first? Request the 2D drawing and 3D model and we will send them once your mounting is confirmed. If you are still choosing, the leveling caster buyer’s guide walks through load calculation and materials, and the applications index lists every scenario we build for. Factory profile, certifications and commercial terms are on the leveling caster manufacturer in China page, with quantities, MOQ and payment terms on the wholesale & OEM terms page.
