Restraint systems

Providing maximum stability while using a cradle

With cradle restraint systems we create maximum stability. During the descent of the cradle workers have to restrain the gondola (to prevent it from swinging). Our innovative restraint systems increase the safety of workers inside of a cradle.

Why choose for a gondola restraint system?

Winds are stronger and more abrupt at great heights, especially around tall objects such as skyscrapers. Nobody wants to be involved in an incident with a swinging cradle, let alone be responsible for the physical and psychological damage.

A restraint system stabilizes a cradle – by keeping it at a fixed distance from the facade. Anyone who’s even been inside a cradle at great heights knows that a stable cradle makes a working at height a lot easier, and therefore a lot quicker.

Three ways to restrain a cradle

Each of these options has its own benefits and possibilities. Which one of these restraint systems is best suited for a specific project depends on your preferences or requirements, as well as on the contour of the building. Below we’ll discuss three ways to secure a cradle to the facade.

With wire ropes attached to the facade

Users attach multiple wire ropes to these pins (or stick pins in attachment points) as they work their way down the facade. In this case, the cable(s) of the cradle are secured to the facade at several points. Albeit effective, this method requires manual effort every time the cradle moves up or down.

  • Requires manual effort.
  • Cradle is secured to attachment points.
  • Straight facades.

With a so-called mullion guide

In this case, the cradle moves over rails that can be integrated in the building’s facade.

On top of the facade, the cradle is fixed in the rails and is then secured for as long as it moves up and down the building. A mullion guide rail provides maximum stability and requires minimal manual effort.

  • Requires minimal manual effort.
  • Cradle is secured in rail.
  • Straight facades.

With pins to a soft rope system

A soft rope system effectively prevents a cradle from swinging, but it serves another purpose as well: uniquely, it ensures that a cradle can get close to a sloping facade.

In contrast to the other two systems, a soft rope restraint system can secure a cradle which moves horizontally along a facade.

  • Requires manual effort.
  • Cradle secured to attachment points.
  • Curved facades.
