are newly divided into manual models, automatic models (electric models) and semi-automatic models. (Telephone) Manual model
The new model is divided into hardcover type, imported upgraded type and aluminum alloy type. The maximum load-bearing capacity of the attic staircase is
new, and the stress of the entire staircase can be reached. Because the extension ladder has telescopic characteristics, its structure adopts the form of steel chain
new connections, so the safety factor Also increased. Features of climbing telescopic stairs: industry-high configuration
New (galvanized) yellow spring and hydraulic rods are manufactured according to German standards
The new wooden frame ensures the overall safety, and the whole body is formed in one step with high-quality spray plastic surface treatment Wider and longer flat steps, newer and more comfortable to use. Stainless steel rivets are safer and more secure to use when riveting with German large-scale automatic rivet machines.
The new adjustable fixed frame can adjust the steps to adapt to the changing floor height and the angle of the stairs. The door frame has standard seals
The new urethane sealing strip reduces the sound of the switch and ensures the air tightness of the upper and lower wooden frames to ensure the overall safety. Safety
The new removable rotating metal lock core (unique) does not touch the head up and down. Special design to reduce the ceiling
The new force deformation is made with long-life custom-made wooden door support hinges to ensure the flexibility of the switch, from the outside Look,
The new wooden board surface is completely flat, no fasteners can be seen. The boards are made of finger-jointed wood (white)
The new modular pre-designed product has thick rubber-plastic bottom corners to protect the floor from Damaged floor height
The secret of the new telescopic attic staircase’s long service life and high safety factor lies in its telescopic height
The new staircase has a galvanized high-strength (yellow) spring and a high-height hydraulic rod. Composed of gold steel pillars. High
The new strength yellow galvanized spring is a must-have for attic telescopic stairs. The spring is a tool for opening and closing the attic telescopic
new stair cover, and is also an important link in controlling the stability of attic stairs. , its quality is related to
the service life of the entire new telescopic staircase and the safety of the staircase. Therefore, every set of products for climbing the attic telescopic stairs
are made of galvanized (yellow) high-strength springs (roots) to ensure quality and safety.
