Installation of an overhead crane in industry

Sizing: the cornerstone of any overhead crane project

Before even considering the purchase of an overhead crane , certain technical decisions must be made. Sizing the equipment is the first key step and directly influences the budget. Indeed, the load capacity, reach, and hook height cannot be determined arbitrarily, otherwise an oversized tool will be immobilized or, conversely, the safety of the operators will be jeopardized.

A thorough analysis of internal needs is therefore essential. What type of loads need to be moved? Are they pallets, metal reels, or packaged products? What are the unit and total quantities to be handled daily or during exceptional operations? Within what area will the loads be moving? These are questions that must be meticulously answered before choosing an overhead crane model.

In addition to the inherent characteristics of the load, the building's infrastructure itself significantly influences the sizing. The floor area, ceiling height, and the strength of the steel structure physically constrain the span of the future overhead crane. Here again, a meticulous site survey remains essential before installation, just as a general inspection is crucial afterward.

Engine and accessories: choices to be made in line with use

Once the dimensions are finalized, it's time to select the peripheral equipment. This begins with the type of motorization, which directly affects maneuverability and handling precision. A manual overhead crane will be suitable for modest loads and short distances.

However, for loads exceeding 1 ton or for repetitive cycles , a motorized system is essential. This can be electric, hydraulic, or pneumatic. Besides the load and frequency of use, the choice will also depend on the environment . Electricity is poorly suited to explosive atmospheres, unlike compressed air.

Furthermore, the crane can be equipped with accessories to facilitate handling operations. Hooks, slings, clamps, magnets, or suction cups are just a few examples of equipment that allow the overhead crane to be perfectly adapted to its use. Here again, a precise definition of the needs beforehand will prevent any over- or undersizing.

Safety first!

Despite seemingly simple operation, an overhead crane poses risks that must be controlled. In addition to the sizing itself, which is guaranteed by the manufacturer, the operator must implement appropriate measures.

The periodic general inspection: regulations to be strictly observed

From a regulatory standpoint, a decree mandates that overhead cranes undergo a periodic general inspection (VGP) by an accredited inspection body. This inspection must be renewed at a frequency that depends on the crane's capacity and usage. The most heavily used cranes must therefore be inspected annually.

During this overhead crane inspection, all elements likely to affect safety were examined. These include:

• the rails;
• the bolts;
• the cables;
• the hooks;
• slings, etc.

Following the inspection, the body issues a detailed report outlining any reservations and providing a recommendation, either favorable or unfavorable, regarding the continuation of operations. In the event of non-compliance, the operator is required to carry out the necessary corrective work.

Although demanding, this regulatory inspection primarily aims to protect the safety of operators working near overhead cranes, especially when these cranes span traffic lanes or work areas. Hence the importance of not neglecting this key step in in-service monitoring.

Train users to prevent accidents

Beyond the machine itself, the human element also influences the safe operation of overhead cranes. Appropriate training for forklift operators and crane operators is therefore essential before any commissioning. This training must cover both the technical aspects of operation and basic safety instructions.

Essential best practices include visually checking for the absence of ground personnel before any maneuver, respecting maximum permissible loads, and prohibiting people from walking overhead. These are simple measures, but when applied rigorously by all, they effectively prevent the risk of accidents.

Installation of overhead cranes: a crucial step

Overhead crane installation is an operation that requires careful preparation and the involvement of qualified professionals. This crucial step begins with a thorough site survey to ensure that the structural and environmental conditions meet the requirements of the selected overhead crane. A detailed installation plan is then developed, taking into account logistical aspects, safety, and specific technical constraints.

The assembly teams, made up of specialized technicians, then proceed with the actual installation. This phase includes the installation of rails, beams, and drive components, as well as the assembly of peripheral equipment such as hooks and slings. Once the mechanical installation is complete, load and operational tests are performed to verify compliance with current safety standards.

The intervention doesn't stop there. Practical training is provided to familiarize operators with the new equipment, with an emphasis on safety procedures and good handling practices. This process ensures that the crane is used optimally and safely from the very first day of operation.
