Installation of Wall Swing Cranes – Step by Step to a Successful Commissioning

Wall Swing Cranes are extremely versatile and compact lifting solutions that are frequently used in workshops, production halls, and warehouses. They provide an ideal means to efficiently lift and move loads, especially in areas where space is limited or other crane systems cannot be used. To ensure that wall swing cranes deliver maximum performance and safety, a professional installation is crucial. Dahs GmbH offers comprehensive services covering the entire process of installing wall swing cranes—from preparation and planning to complete commissioning.

This section describes in detail how the installation of a wall swing crane is carried out and which preparations are necessary to ensure smooth and safe operation.

1. Preparation – Analysis and Planning

The successful installation of a wall swing crane begins with careful and detailed planning. Before the actual installation, various technical, structural, and logistical aspects must be considered to ensure that the crane can operate efficiently and safely. The most important preparatory steps include:

Site Analysis

The first step in the preparation process is to analyze the planned installation site for the wall swing crane. Several factors must be taken into account, including:

• Load-bearing Capacity of the Wall: Since a wall swing crane is mounted directly on a load-bearing wall or support, the structure must be capable of safely carrying the loads. This includes not only the weight of the loads to be lifted but also the dynamic forces generated during the crane's swinging motion.
• Space Availability: The crane's swing radius as well as the space required for load pickup and movement must be carefully planned. It is important to ensure that no obstacles are present within the crane's swing range that could impede its motion.
• Height and Working Area: The ceiling height and the available working height for the crane arm must also be considered to ensure that the crane has sufficient clearance.

Technical Planning

After the site has been analyzed, the technical planning of the crane follows. This involves determining which type of wall swing crane is best suited for the intended application. Key considerations include:

• Crane Load Capacity: Based on the operational requirements, the crane's load capacity is determined. It is essential that the crane can safely support both the maximum load and the dynamic stresses.
• Swing Range: The crane’s swing range – typically between 180° and 270° – must be adapted to the spatial conditions and operational requirements. The entire work area and potential obstacles must be taken into account.
• Boom Length: The length of the boom determines how far the crane can reach into the work area. The correct boom length ensures efficient utilization of the crane without wasting space.
• Choice of Lifting Device: Wall swing cranes can be equipped with different lifting devices, such as electric chain hoists or worm gear block and tackles. The selection depends on the load, lifting speed, and precision required for the application.

Permits and Safety Requirements

Another important aspect of the preparation is compliance with all relevant construction and safety regulations. In many cases, installing a wall swing crane requires a building permit or approval from occupational safety authorities. It is also essential to adhere to applicable standards and regulations, such as DIN EN 13001 for cranes.

Dahs GmbH also takes care of these tasks, ensuring that all necessary permits are obtained and that the crane complies with legal requirements. We handle communication with the relevant authorities to ensure a smooth installation process.

2. Preparation of the Installation Site

Before the wall swing crane can be installed, several preparatory measures must be taken at the installation site. These include:

• Reinforcement of the Walls: If the wall or support where the crane will be mounted is not sufficiently load-bearing, reinforcement measures must be taken. This may involve installing steel beams or other supporting structures. The static calculations and execution of these measures must be carried out by professionals.
• Inspection of Mounting Points: The points at which the crane will be mounted on the wall must be inspected to ensure they can withstand the load. Drilling and mounting must be precisely positioned and prepared to guarantee safe installation.
• Clearing the Work Area: The area where the crane will be installed must be free of obstacles so that the installation team can work unhindered. All tools, equipment, and materials required for the installation should also be ready.

Dahs GmbH ensures that all preparatory work for the installation is carried out meticulously. Our experienced installers work closely with the site managers to ensure that the installation area is optimally prepared.

The actual installation of the wall swing crane is a complex process that should be carried out by experienced technicians. The installation process includes the following steps:

Mounting the Crane on the Wall

Installation begins with mounting the crane arm on the prepared wall or support. This requires precision and care to ensure that the crane is securely installed and aligned. The following steps should be observed:

• Fixing the Boom: The crane’s boom is secured to the wall using special heavy-duty anchors or screws. These must be firmly embedded and tested to ensure they can withstand the loads.
• Alignment and Leveling: The crane arm must be precisely aligned and leveled to ensure smooth operation. Measuring instruments are used to ensure that the crane is installed in the correct position.

Installation of the Lifting Device

Once the crane arm is mounted, the lifting device is installed. This may be an electric chain hoist, a worm gear block and tackle, or another lifting system. The installation of the lifting device includes:

• Securing the Lifting Device to the Crane Arm: The lifting device is attached to the designated mounting point on the crane arm and securely fixed. It is essential that the lifting device is installed stably and safely to ensure secure lifting of loads.
• Connecting the Power Supply: For the installation of an electrically operated lifting device, the power supply must be properly connected. This includes connecting to the operational electrical system as well as installing emergency stop switches and other safety devices.

Functional Testing and Commissioning

Once the crane is installed and the lifting device is in place, comprehensive functional tests are conducted. All movements of the crane are tested to ensure smooth operation and compliance with safety requirements. Key tests include:
