Use of a construction cradle and principle of operation

Construction cradle, also known as a lifting rig or hoist, is specialized equipment, used for lifting workers and materials to heights during construction work. It is widely used to perform work on building facades, repair or maintenance of tall structures. Depending on the design and needs of the task, There are several types of construction cradles, detail

Design and principle of operation of a construction cradle

Construction cradle, or lift, is a mechanized equipment, used to lift workers and materials to a height during construction, repair or maintenance work on building facades. The use of a construction cradle provides workers with safe and convenient access to high points of the building. The operating principle of a construction cradle depends on its type and purpose..

Although specific details may vary depending on the model and type of lift, common elements include:

  • Mast post. Basic vertical design, to which the working platform is attached. The mast post serves as the main support element and guide for the movement of the platform up and down.
  • Working platform. Surface, where workers stand and work. The work platform is usually equipped with guards and anchorage points for the safety of operators.
  • Drive mechanism. Mechanism, responsible for the movement of the platform up and down. It could be a hydraulic system, electric drive or a combination of both.
  • Management. Remote Control, on which buttons and levers are located to control the movement and position of the platform. Control can be located on the platform itself or at a ground station.
  • Security systems. Includes fall prevention systems, emergency brakes, fuses and other devices, ensuring operator safety.
  • Power supply. If the lift is electric, then the presence of power supply, cables and electrical control system. Monitoring systems, including safety sensors, battery level indicators, system status indicators and other elements.

These components work together, ensuring smooth and safe movement of the platform along the mast post. The operating principle is based on controlling the movement of mechanisms, support and stabilization of the structure, as well as ensuring the safety of the work area. Construction cradle operator controls it, monitors safety and effectively performs work at heights.

Installation and preparation

Before using the construction cradle, it must be correctly installed and secured to the building. This includes checking the stability and security of the fastening, as well as the belief that, that the installation location complies with safety requirements.

Installation and preparation of a construction cradle for work are important stages, which require strict compliance with safety rules and technical requirements. Below are the general steps for installing and preparing a construction cradle:

Choosing an installation location

Select installation location, that meets manufacturer's requirements and local safety regulations. Check out, that the surface, to which the cradle will be attached, quite strong and stable.

Before starting work, make sure, that the working platform of the construction cradle is in good condition. Check for damage, corrosion and serviceability of all elements.

Make, what is the place where the cradle is attached to the building (usually the facade) reliable and safe. If necessary, use additional fastening elements, such as anchors or bolts.

If provided, install stabilizers for added stability. This is especially important when working on uneven surfaces. If the construction cradle runs on electricity, connect it to a power source. Check electrical components for damage.

Checking security systems

Check the functionality of all security systems, such as emergency brakes, circuit breakers, fall protection systems, etc.. Test the drive and lift controls thoroughly before starting work.. Make, that all mechanisms are working correctly. Before raising the cradle to a height, inspect the work area for obstacles, dangerous objects and other possible threats. Prepare the necessary tools and materials on the construction cradle platform, to avoid the need to frequently go down for them.

Remember, that these steps are provided in general terms, and actual steps may vary depending on the model and manufacturer of the construction cradle. Always follow manufacturer's instructions and local safety standards.

Raising and lowering control

Modern construction cradles are usually equipped with mechanisms for raising and lowering the platform. It could be a hydraulic system, electric drive or a combination of both. The operator controls these mechanisms, raising or lowering the work platform depending on needs. Some construction cradles may also have mechanisms to move the platform along the front of the building or in other directions. This allows workers to move efficiently around the work area at height.


Operators of construction cradles must adhere to strict safety regulations. This includes the use of security systems, such as guardrails and seat belts, as well as compliance with operating instructions.

Types of construction cradles:

As mentioned earlier, There are several types of construction cradles, such as mast, false, block, etc. Each type has its own characteristics and operating principle.

The use of construction cradles improves productivity and safety of work at heights, making them an integral tool in modern construction and building maintenance.

An important aspect of using construction cradles is strict safety control, including ensuring correct installation, secure fixation to the building and training workers on safety rules when using lifting equipment.
