Ceiling drill rig with crank stroke
With this practical innovation, you can drill overhead almost effortlessly, even in hard concrete ceilings or steel beams etc.. The use of core bits is also possible.
Due to the central power transmission via the machine and the holding tube/chassis against the floor, no lateral forces are generated. You also have a high degree of flexibility, as the device can be moved independently of the drilling location and the ceiling. A quick change to the next drilling point is possible because no clamping to the ceiling is required.
The crank device is very flexible in terms of height adjustment and the feasible drilling depth thanks to the crank adjustment over approx. 800 - 1000 mm. The possible drilling diameter depends on the material hardness. For steel or reinforced concrete, this is max. approx. 12 mm. For softer materials or when using core bits (lower cutting pressure), larger drilling diameters are also possible. The standard crank device is suitable for clear room heights from 2.40 m to 3.30 m*. The shorter KK version of the crank device enables room heights from 2.20 m to 3.10 m*, but with a maximum stroke of 550 mm.
The simple height adjustment makes the device very flexible with regard to changing clear room heights and thus also enables deeper drill holes with significantly more than 100 mm. If long drill bits up to e.g. 40 cm are used and drill holes up to 40 cm deep are required, this must be taken into account in the possible clear room height. The above information is based on drill bit lengths and drilling depths of approx. 150 mm. The KKS version has a maximum shortened basic height and can therefore be used for room heights from 1.85 - 2.25 m* or, with longer drill bits and greater drilling depths, for greater room heights.
As a measure of the maximum load of the device, the comparison with possible manual drilling from the arm should be used.
*To calculate the possible room heights yourself, please refer to the information below on the 3 length variants.
The device with lever stroke, which is still shown in some cases, is no longer produced, as the crank devices are equivalent and offer more flexibility for room height adjustment and for the possible drilling depth due to the large possible height adjustment up to max. 1000 mm. This device can also be used for ceiling breakthroughs, which are particularly useful when renovating damp floors and insulation from the floor below.
This device is also suitable for the application"fixing of glued ceiling insulation panels using plate anchors" or the Heraklith concrete screw DDS plus. Thanks to the large drilling stroke, the holes for these fixing plugs can be drilled in one go, first through the soft isopanel and then in the concrete ceiling.
Your existing drilling machine* is clamped in the machine holder of the drill stand using the clamping neck clamp (standard D=43 mm, other sizes on request up to max. D=60 mm).
The triangular chassis made of a sturdy 6 mm steel plate, stove-enameled silver-grey and equipped with 3 rotating industrial wheels, offers good tipping safety as a counterbalance to the drilling machine. As an accessory, we offer the "alternative pipe holder" off-center above one of the wheels. This makes it possible to drill holes in the ceiling even with a small distance to the wall.
The drill holder of the ceiling drill rig is made of aluminum. The mast with rack and pinion crank is made of steel.
*Please check the dimensions of your drill: 1. diameter of the clamping neck (cylindrical part directly behind the drill chuck, often e.g. also for holding a side handle), 2. length of the machine housing from the rear edge of the clamping neck may be max. 310 mm and 3. center of drill to narrowest outer edge max. 34 mm. Below you will find a photo to help you determine the maximum dimensions and parameters of your drill.
*To determine the right length variant for you, we will give you the respective length dimension of the ceiling drill stand without drill and drill bit. Lowest position for the standard version "K" 228 cm, for the shorter version "KK" 208 cm and for the shortened version "KKS" 168 cm. To determine the lowest usable room height, please add the total length of the drill chuck + clamped drill bit + distance between drill chuck and drill housing. Total dimension + at least 1 cm gives the lowest clear room height in which the ceiling drill stand can be used.
If you require a chuck diameter other than 43 mm for your existing drill, we can adapt the clamping neck clamp to your individual dimensions from 43 mm to max. 60 mm. Please add this to your order and specify the required size.
This device makes time-consuming and strenuous drilling work easier, especially when drilling many holes directly from the arm and often also from a ladder. The ceiling drill rig can be seen as a preliminary stage to the Hilti drilling robot "jabot" for all users who do not only want to use such an auxiliary device on large construction sites.
From various drill manufacturers. Drill manufacturers now offer special drills with a suction connection from diameter 6/8/10/12 mm. We have seen these at Fischer-Dübel and at Heller as so-called DUSTER EXPERT carbide drills and have had good experiences with them. The direct extraction of drilling dust in the drill bit is a great advantage and makes this overhead work even easier. We will be happy to answer any further questions you may have.
When using wet core bits, we recommend extraction systems from Hilit such as the DD120 water collection system or DD-WMS 100.
As an accessory, we offer an additional mast mount on the chassis above one of the wheels. This allows you to drive the chassis much closer to the wall when drilling holes in the ceiling close to a wall.
The time and effort saved will pay for this device in no time at all!
Supplied pre-assembled in 2 boxes for easy final assembly. The drill stand can be dismantled into 3 - 4 handy individual parts for quick transportation from site to site.
The development is protected. Short application video available.
