Construction company purchases bridge crane and automatic hook to lift steel profiles

The case that Dongqiクレーン will introduce today is that a global supplier of construction systems and materials uses automatic hooks with overhead cranes to lift steel profiles at two locations in eastern フランス. The steel and mining giant's construction arm produces a variety of building components including roofing sheets, cladding and laminate flooring at its factories. Safety is paramount throughout the entire manufacturing and material handling process.

When supplying bridge cranes and automatic hooks, crane suppliers need to comprehensively consider various factors such as the construction company's needs, safety performance, quality assurance, and after-sales service to ensure that they provide high-quality products and services that meet the requirements.

Bridge cranes and automatic hooks in material handling

Arnauld Clausse is the head of the Panneaux (team) in Zone 2 of the I construction site, responsible for the safety of the contrisson and Haironville construction sites, which are located in the eastern part of Paris and are approximately 30 minutes away by car. These facilities are conveniently located and can distribute products to France and neighboring European countries. Klaus said, "My mission is to continuously improve the safety of the site. Part of our operations is to load steel sections onto trucks for transportation. As part of our efforts to continuously improve best practices, we are seeking a method of connecting and dismantling lifting straps without human intervention."

The company mainly purchases 5 tons of hooks, but also has 10 tons and 20 tons of equipment. The three hooks are usually located on one side of the eight pick-up point drilling rig suspended below the overhead crane. Each magnetic hook attracts and positions a sling connected to the opposite rigging point, and wraps it around a bundled profile weighing between 50 kilograms and 5 tons.

The most common practice is to use only two hooks at both ends of the load, but Klaus explains that the central hook is an important component of the drilling rig because when only one sling is needed, it can independently handle smaller loads.

He added, "In all material handling operations, hooks do not require personnel to work at heights or near loads. They do not need to climb onto loads to prepare elevators, nor do they need to climb onto truck trailers to disconnect rigging equipment. For example, the hazards associated with falls or getting stuck in hands have been eliminated from our operations, so these hooks will be installed in other locations throughout France."

The construction company uses a remote control, which includes a full-color liquid crystal display (LCD) that can provide users with various information about lifting applications, including weight, hook status, and alerts to operators for overload or imbalance.

このことから何を学べるか

In the field of crane services, most customers need to develop customized crane solutions based on their actual working environment. This is clearly the same in the construction industry. From this case, we can notice that the most important reason for customers to use automatic hooks is safety, which is a method of connecting and dismantling lifting straps without manual intervention. When used in conjunction with bridge cranes, it maximizes safety and efficiency. Based on these contents, we can summarize some key points to pay attention to when designing crane solutions for construction companies:

Crane selection and configuration:

Based on the actual needs of the construction company, determine the appropriate crane model, rated lifting capacity, span, lifting height and other parameters.
Ensure that the crane configuration meets the actual working environment and operational requirements of the construction site, including power supply, rails, control systems, etc.

Security and reliability:

Emphasize the safety performance of the crane and ensure that it has safety measures such as overload protection, limit protection, and collision prevention protection.
Choose reliable electrical and mechanical components to ensure stable operation and long service life of the crane.

Materials and Quality:

Use high-quality materials to manufacture cranes, especially key components such as main beams, hooks, wire ropes, etc., to ensure their strength and durability.
Strictly control the quality of the production process and ensure that each crane undergoes strict inspection and testing.

Matching and debugging of automatic hooks:

Design and manufacture suitable automatic hooks based on the dimensions and weight of steel profiles provided by the construction company.
Accurately debug the automatic hook to ensure its coordination with the crane and achieve efficient and accurate lifting operations.

Service and after-sales service:

Provide comprehensive pre-sales, in sales, and after-sales services, including technical consultation, installation and debugging, and training of operators.
Establish a comprehensive after-sales service system and promptly solve problems encountered by construction companies during use.

Price and cost-effectiveness:

Provide reasonable prices to avoid construction companies being unable to afford high prices.
On the premise of ensuring quality, try to provide products with high cost-effectiveness to meet the actual needs of construction companies.

Regulations and standards:

Ensure that the crane complies with national and local regulations and standards, such as safety regulations, environmental requirements, etc.
Provide necessary certification and inspection reports to demonstrate the compliance and reliability of the crane.

Customized requirements:

According to the special needs of construction companies, provide customized crane solutions to meet their specific working environment and requirements.
