The following video shows how you can easily assemble a lifting piston.
We have a table for calculating the weight of a door, which is necessary to know when choosing guy ropes and measurements.
Depending on the material of the door, as well as its dimensions, the result will be the weight of the door (kg) that you can use to calculate to the necessary strength of the measure (Kg x cm).
A kilogram-force or kilopond, is the force exerted by 1 kg of mass by standard gravity on the earth’s surface which is 9.80665 m / s2.
1 kp = 1 kgf = 1 kg × 9,80665 m / s² = 9,80665 (kg x m) /s² = 9,80665 N
Therefore, kilogram-force or kilopond is what a mass of 1 kg weighs on the earth’s surface. That is to say, a kilogram-force or kilopond amounts to 9.80665 N
We use the concept of kilogram-force to specify the characteristics of dampers or pistons in our catalogue, however it is necessary to bear in mind that there are times when you can use one concept or another.
The following video shows how you can easily assemble the Microwinch system.
The choice of a system for fold-down doors using a steel cable, like Microwinch or Miniwinch, depends on the height and weight of the door. To do so, you simply need to follow these simple steps:
1. Check the height and the weight of the door.
2. Once you have obtained the values, look up the selection table.
Depending on the weight of the door, you will be able to choose one fold-down system or another. Also, the table will indicate the number of systems needed for said door (x 1 or x2).
We have a table for calculating the pistons or dampners, where you can obtain a response with the furniture data.
The choice will depend on the width and the height of the door, as well as the material it is manufactured out of, in addition to the stroke of the piston or damper itself.
The result will be the number of pistons or dampners and the necessary strength of each one.
For the same force required in both folding and lift up doors, we recommend that you only use a single piston or damper in a door with a width of less than 450 mm, and that you use two pistons or dampers for a door that is wider than 450 mm.
The choice of a system for Agile lifting doors depends on the height and the weight of the furniture door. To do so, you simply need to follow these simple steps:
1. Check the height and weight of the furniture door.
2. Once you have obtained the values you need to calculate the strength of the spring, S = H * (W + 2 * Wh), in terms of:
H = Height of the door in mm.
W = Weight of the door in kg.
Wh = Weight of the handle in kg.
You can choose the lifting system according to what interval the strength of spring S falls under.
The LOW interval is between 580 and 1,250, MEDIUM between 960 and 2,040, HIGH between 1,800 and 3,500, and EXTRA HIGH 3,200 y 9,000.
For example, we have a door with a height of 400 mm and a weight of 5 kg, with a handle that weighs 0.22 kg.
The strength of the spring would be S = 400 * (5 + 2 * 0.22) = 2,176.
Therefore, we would choose the HIGH strength range because it is in the interval of 1,800 to 3,500.
