Specifications:
The document outlines the specifications for two types of Visolift lifters: asymmetrical (VA260L700587HHH24) and symmetrical (VS260L460375HHAAD). Both lifters operate at a voltage of 24 V/DC and have a maximum power input of 144 W with a power consumption of 6 A. They are designed to operate within an environment temperature range of +10 to +40°C and have a protection rate of up to IP54.

Performance Parameters:
The Visolift asymmetrical model has a maximum push force of 2200 N and a pull force of 1100 N, while the symmetrical model has a push force of 1500 N and a pull force of 750 N. Both models can handle a maximum static lengthwise load of 1200 Nm and a dynamic load of 500 Nm. The static lateral load capacity is 450 Nm, with a dynamic capacity of 225 Nm.

Design and Construction:
Both lifters are 3-stage versions with a standard retracted length of 587 mm for the asymmetrical model and 375 mm for the symmetrical model. The standard stroke is 700 mm and 460 mm, respectively. Custom stroke lengths are available on demand. Fixing points for both inner and outer profiles are 4 x M8 screws.

Operational Features:
The lifters have a speed of 12 mm/s (asymmetrical) and 15 mm/s (symmetrical) without load. They include integrated end switches and use a Molex Mini Fit Jr. plug type. The cycle duty is 1/9 (10%), and the pulse travel length is 0.2268 mm/signal for the asymmetrical model and 0.1568 mm/signal for the symmetrical model.

Additional Information:
The document mentions that stroke tolerance is +/- 2mm and that operating speed depends on load and voltage. It also notes that other retracted lengths, strokes, and pull applications are available on demand. The screws used are self-cutting/forming according to DIN 7500, with a minimum thread depth of L= 2.5 x D.
