LinkLift

For 45 years, SERAPID has been designing, manufacturing and distributing a wide range of telescopic and linear actuators. Its field of application is focused on the moving of loads, linear transfers and lifting systems, in all areas of industrial activity.

These telescopic actuators are designed on the simple mechanical principle of the Rigid Chain, which allows the transfer of loads from a few kilograms to several hundred tonnes. This technology is based on the locking and unlocking of connected, linked elements. When lifting a load, the specially shaped chain links interlock with each other, forming a rigid bar or column. When lowered, the links unlock, allowing it to bend to store into a compact package.

Whatever your challenge, our teams are at your service to offer you the precise solution adapted to your needs and to accompany you throughout your project.

LINEAR TELESCOPIC LIFTING COLUMNS FOR INDUSTRIAL APPLICATIONS

Advantages of SERAPID’s range

Our rigid-chain technology combines the strengths of other transfer methods, such as hydraulics, belts or spindle screws, and at the same time it eliminates their weaknesses:

high speeds with permanent lubrication in oil bath (HD Lift version)

a robust design allowing a long service life and the use in harsh environments: clean-room conditions, dust, temperature, humidity, radiation

repeatable positioning in the millimetre range, even at high speed

designed for low vibration and noise low maintenance

ATEX certified, category II 2GD c T4 maintains position with no drift specific applications on request: stainless

steel, suitable surface treatment, specific heat treatment

options and accessories : limit switch, encoder, protective bellow, interface, special hub, output shaft

The ChainLift is designed for applications with an average frequency of use, between 5 and 15 cycles per hour. It will be suitable, for example, for a workbench lift in automotive manufacturing. The nominal lifetime is 250,000 cycles. Lubrication maintenance is required every 13,000 cycles in the first year and then every 50,000 cycles (or every year).

The LinkLift was specifically developed for the needs of the theatrical industry, but it has proven to be equally well-suited for industrial applications.

It is suitable for low frequency applications (< 5 cycles/hour), for example, lifting manufacturing work platforms. The lifetime is 50,000 cycles (standard) or 250,000 cycles (MD - Medium Duty version) with a maintenance of lubrication that is required every 2,000 cycles (standard) and 13,000 cycles (MD) the first year; then every 10,000 cycles (standard), 50,000 cycles (MD) or every year.

Note: load capacity and stroke are given relative to each other - a lower stroke allows a higher load and vice versa. For example: “50: 2” means the maximum load is 50 kN up to a stroke limit of 2 m ; “10: 4” means the maximum stroke is 4 m up to a load limit of 10 kN. Please note maximum speed cannot be combined with maximum load or stroke.

Long guides

Main LINKLIFT options

The drive housings can be fitted with standard or long guides. The long guides are required in the following two cases: 1. to reduce deflection when the stroke is long (see the load / stroke performance curves on page 10).2. to stabilise the chain when exiting or entering the drive housing at speeds above 200 mm/s.

Modular magazine

Our standard dual-line magazines consist of two parallel aluminum tubes with a 180° curve piece connecting them at one end; the tubes can be cut to any size. This allows the magazines to be fitted exactly to the length of the lifting column. In installed lift systems, if the stroke is to be extended, additional storage space can be obtained by simply replacing the tubes (according to prior analyse from SERAPID).

Planetary gearbox

All LinkLift models can be delivered with a planetary gearbox to reduce the drive torque. The gearbox is selected according to the torque used. The gearbox comes pre-mounted with the appropriate flanges on the drive housing.

Positioning control using a CAM switch

A CAM switch can be connected to the drive shaft with an appropriate mounting bracket. The switch is available with 2 to 6 positions which can be set independently of each other.

Positioning control using an encoder

An encoder can be connected to the drive shaft with an appropriate mounting bracket. With a resolution of 1 024 points per travel, the positioning accuracy obtained at the end of the column is 0.5 mm.

Load monitoring

The LinkLift load cell allows load monitoring at the top of the lift column, the point where the force is applied. The deformation body contains a force transducer with a thin film sensor for high accuracy.

Consider the forces generated by a shut-down due to a power loss, particularly with speeds above 100 mm/s

Lengths and weights of LinkLift standard magazines

The total length of the magazine (M) is composed of the basic length, which depends on the model for a stroke of 500 or 1 000 mm, and the length of the double-return magazine that is also required. This is measured in standardised steps, where the base is extended by 50 mm per 100 mm stroke (no intermediate dimensions). In the basis length, the 180 ° deflection, the brackets, the housing connection and two links contain a storage reserve.

Values are given for all LinkLift models in the table below.

The weight of the magazine consists of the weight of the base and the weight of the double-return magazine, depending on the stroke (in m). The corresponding values can also be found in the table below.

To ensure stability in the upper portions of the operating ranges, the LinkLift’s drive system uses special components, in particular a double-key or splined shaft and longer drive guides.

For loads above this limit, the drive system is equipped with a double-key or splined drive shaft. For strokes above this limit, the drive system is

fitted with long drive guides.

Long guides increase the lowest possible position of the platform above the nominal closed height of the LinkLift as follows:

LinkLift 50 / 50R: 366 mm ( : + 75.5 mm) LinkLift 80 / 80R : 580 mm ( : + 120 mm) LinkLift 100 / 100R: 722 mm ( : + 150 mm)2

The following basic formulae are used to calculate the torque, speed and power required.

The maximum torque (M) per column is calculated from the total static (Fs) or dynamic load (Fd), whichever is the higher. This value is divided by the number of columns.

Motorisation

We generally recommend a frequency converter to minimise shock; other-wise, the speed must not exceed 30 mm/s.

N = [U/min]

The output power (P) required per column is calculated from the torque (M) and the shaft rotation speed (N):

P = [kW]

V2π x p x 10-3

M x N x π x 10-3

The number of cycles in relation to the capacity

The weight of the chain is then added. Friction forces occurring in the guides are insignificant. Forces of inertia must be added if the system does not include a speed variation control.

Fs = [N]

Fd = [N]

Pc = Ct x m [N]

M = [Nm]

The rotation speed of the drive shaft (N) is calculated from the chain pitch (p) and the lifting speed (V).
