How to install a lift mechanism for a gas lift bed

Consider what constitutes a gas lift, the advantages and disadvantages of beds with this mechanism. Let's get acquainted with the device, the principle of operation and technical characteristics. We will also consider the correct selection, features and rules for self-repair.

What is a gas lift for a bed

Many bed models have a gas lift for the bed. This is a special mechanism that is used to lift the surfaces attached to it. It greatly simplifies and facilitates the procedure for raising the bed of the bed. There are two types of gas elevators used. Automatic devices do not require human effort and control and frictional, which are used relatively rarely.

Advantages and Disadvantages of Gas Lift Beds

A bed with a gas lift has the main advantages:

• A variety of bed designs. They are available in rectangular shape, with a round bed;
• Practicality. Convenient storage space for blankets, bed linen, seasonal clothing;
• Strength and reliability of the mechanism;
• Ease of handling. The top of the bed can be folded back quickly, without much physical effort. No special lifting skills required;
• Profitability. The space under the bed can be used instead of a closet and even fragile items can be stored;
• Saving space. Unlike pull-out drawers, no space is required in front of the bed;
• Durability. It can serve up to 10 years.

The main disadvantages of beds with a gas lift:

• Price. The price of beds is slightly higher than the usual types;
• Possible dust collection;
• Some inconvenience. Access to things under the bunk can be problematic (two partners use the bunk).

How the mechanism works

The lifting mechanism includes parts:

• high pressure inert gas cylinder;
• oil damper (in an automatic mechanism);
• piston with rod.

Principle of operation and technical characteristics

When the bed of the bed is raised, the gas expands, presses on the piston. It pushes the bed upward, reducing the person's efforts. The use of an oil gasket in the body allows for a smooth ride. Due to the lack of a damper when installing the friction mechanism, you can stop the movement of the device at any time.

Cylinder, rod, piston and support ends are made of steel.

Main technical characteristics:

• the ability to work in the temperature range of -30 - +80 degrees;
• maximum stem speed - up to 300 mm / s;
• pressure inside the cylinder is not more than 160 bar;
• cylinder wall thickness not less than 1 mm.

How to choose the right one

When choosing a mechanism, it is necessary to consider:

• The force that the system can deliver, taking into account the angle of inclination. For a large bed, the force should be in the range of 200-300 N;
• Number of gas lifts installed. The force of compression depends on their number. They prefer to install no more than two products;
• The length of the device. The angle of the bed depends on the parameter;
• Manufacturer. The best option is the choice of products from German companies. Domestic-made mechanisms are also deservedly popular, judging by the reviews.

Installation and adjustment instructions for the gas lift for the bed

The service life of the gas lift depends on the correct installation.

The installation of a bed lift using gas lifts should be strictly followed according to the manufacturer's instructions.

In order to assemble a bed with a gas lift, you need to follow several of the following basic steps:

• Assemble the bed frame according to the manufacturer's instructions;
• Install gas lifts. The structure is fixed using studs or special self-tapping screws (usually included in the kit). The mechanism is attached to the bed frame by the gas lift eyes. Some structures have a specific design and are one-sided. In this case, it is important to install them on the correct side (pay attention to the configuration of the cylinders);
• Assemble the folding orthopedic bed frame. The lattice frame can have various configurations. It usually has an all-metal construction. Sometimes it is made from lamellas of wood or other material (follow the manufacturer's instructions);
• Fasten the gas lift to the top folding element of the bed. The device is attached to the bottom of the bed when the folding part is open. It is better to install mechanisms on a bed together. One should hold the upper hinged grill, and the other should install the fixtures. It is important to install with the stem down (cylinder on top). Installing the gas lift with the stem up is the most common mistake and can lead to structural failure. If the stem is installed upwards, the retaining stud and mounting lugs are kinked. When fastening, it is important to fix the nuts without constriction. Otherwise, the mechanism will not move freely, you can break the thread. Devices with a stem at the top are very rare and this must be reflected in the manufacturer's passport;
• Run the system several times to check the functionality after assembling the entire structure.

If the system does not work well, you must reinstall the fixtures.

When inaccurate movement is detected, it is important to troubleshoot immediately. You will need to adjust or reinstall the mechanism again. Otherwise, they will quickly fail during use. The angles of inclination can be adjusted to adjust the fixtures. The gas lift cylinder is threaded on the inner surface. By turning the mechanism, you can lengthen or shorten it slightly. You can also make markings on the base of the bed to install the mechanism in another place.

How to repair with your own hands

The lift mechanism can only be removed for repair if it is not compressed and the cylinder is not damaged.To repair a gas lift, you need, first of all, to know its design and find out the reasons for the malfunction or breakdown of the device.

You need to pay attention to the following points:

• The lifting mechanism must be installed only in the open position of the gas lift;
• The fixing points of the device must be well secured in the lugs with the fixing pins and bolts. Fastening must be done so that the device moves freely when raising and lowering the top of the bed. Studs and bolts must not be overtightened;
• Dismantling is carried out in the open position of the gas lift, you need to start by unscrewing the fasteners.

The main causes of malfunctions or breakdowns:

• Ingress of dust, chemicals, mechanical damage. This can lead to damage to the seals of the mechanism, significantly reducing its service life. During operation, the gas lift should be protected;
• Oil leakage or gas leakage from the device. You can fill the cylinder with grease. In no case should you try to open the gas lift, since there is high pressure inside the cylinder;
• Incorrect selection of the power of gas lifts from the very beginning. They are selected approximately at the rate of 10 N per 1 kg of load. If the base of the bed with the mattress weighs about 30 kg, then each device must be designed for 300 N. In case of an error in the calculation, the device must be replaced.

If the damage is serious, the fixture must be replaced. In case of minor malfunctions, you can simply make additional adjustments.

In what cases is the help of a specialist needed

Installation of gas lifts has many nuances. If you are poorly versed in the mechanisms and the reason for the failure is not clear to you, you are not sure that you can perform the installation efficiently, you should entrust it to an experienced specialist. The best option is to order furniture assembly or repair to specialists. They will select the style, size and design of the piece of furniture. The optimum lifting performance will also be determined.

Recommendations and Tips

It is important to know that gas lifts vary in size, metal thickness, and load capacity.

The length of the gas lift is the distance between the two end lugs of the mechanism. There is grease inside the cylinder, which, during operation, flows down and lubricates the mechanism. Thanks to a properly installed gas lift, the bed base can be lifted easily.

After attaching the attachments, it is imperative to check all the lifting angles.

If a long-term storage of the gas lift took place before installation, then at first it can work with significant effort.

Checking the performance of devices should be on the bed with a mattress. Without its load, the frame may not hold in the closed position and will rise.

It is not worth checking the performance of the gas lift with your hands, since a serviceable device should not be compressed. And if it shrinks from the effort of the hands, then it means it is broken. A gas spring from 300N cannot simply move under the force of the hands.

The mechanism must not be hit, cut or heat the cylinder - there is high pressure inside and this can be dangerous to health.

During operation, it is also worth avoiding bends, curvatures of the mechanism.
