About workstation crane

Types of workstation cranes

A workstation crane is a lifting device used in a factory to transfer materials from one point to another. The following are some common types of workstation cranes.

  • Bridge cranes

Bridge cranes are a type of workstation crane in which the bridge runs parallel to the runway. A bridge crane has two rails that are installed high in the air. The bridge is mounted on wheels and runs along the two parallel rails. Bridge cranes can be top running or underhung. They are commonly used in assembly lines and workshops to lift, lower, and transport materials in a long distance.

  • JIB cranes

JIB cranes are a type of workstation crane with a horizontal arm that supports a movable hoist. The horizontal arm can rotate around the pillar to provide a wide range of movement. JIB cranes can be wall-mounted or floor-mounted. They are usually used in workstations and assembly lines to handle materials in a small area with a wide coverage.

  • Gantry cranes

Gantry cranes are a type of workstation crane that is supported by two or more legs and can move on the floor. Similar to the bridge cranes, the gantry cranes have a bridge that runs along the runway. Gantry cranes can be single-girder or double-girder. They are commonly used in warehouses and outdoor yards to handle materials and heavy loads in a specific area.

  • Articulating arm cranes

An articulating arm crane is a type of crane with a jointed arm structure. The arm can be folded and expanded like a human arm. The end of the arm is equipped with a hoist to lift and move materials. Articulating arm cranes are usually mounted on the column or the wall. They are used for precision lifting and handling in confined spaces or where the material needs to be positioned with a high level of accuracy.

Specification and maintenance of workstation cranes

The specifications of a workstation crane vary depending on its type, model, and application. Here are some typical workstation crane specifications.

  • Capacity

The workstation crane's maximum load weight is its lifting capacity. It is crucial for the crane's safety and performance to choose a workstation crane with the appropriate capacity for the intended application. Typically, a workstation crane has a capacity ranging from a few hundred kilograms to several metric tons.

  • Span

The span of a workstation crane is the horizontal distance between the crane's runway and its support structure. The span can vary depending on the design and application needs. For some workstation cranes, the span may be fixed, while for others, it can be customized to suit specific workstation layouts. The span of a workstation crane determines the coverage area where it can move and position loads within the workstation.

  • Lift Height

The lift height of a workstation crane is the maximum vertical distance over which it can lift and lower loads. The lift height is determined by the length of the crane's vertical mast or boom. The lift height of a workstation crane may be fixed or customizable based on the application requirements. Workstation cranes with adjustable heights can be set to different positions to accommodate various load sizes and stacking heights within the workstation.

  • Power Supply

Workstation cranes are typically electric-powered and are available in different power supply options, including AC (alternating current) and DC (direct current). Additionally, workstation cranes can be powered through overhead lines or self-contained cable reels. The power supply options allow for flexibility to meet specific workstation requirements.

  • Periodic maintenance

For workstation cranes to perform optimally and enhance their longevity, they must undergo regular maintenance. The primary goal of maintenance is to ensure the crane is safe to use, and it will minimize the risk of failure.

An essential part of maintaining a workstation crane is performing routine inspections. Users should check for any signs of wear, damage, or loose components. They should also check the crane's operating system to ensure that it is working correctly. Routine maintenance should include lubricating movable parts, inspecting the electrical system, and tightening fasteners and connections.

It is also important to keep records of all maintenance and inspection activities for future reference.

Scenarios of workstation cranes

Workstation cranes are widely applied in various industries and work environments that require lifting, moving, and positioning tasks. Some common scenarios are as follows:

  • Manufacturing and assembly

In manufacturing workshops, workstation cranes are usually used to move components, position workpieces, and assemble products. They can improve operational efficiency and accuracy.

  • Warehousing and logistics

In the warehouse or logistics center, workstation cranes can be used for container loading and unloading, order picking, and inventory management. They can improve the speed and flexibility of material handling.

  • Maintenance and repair

Workstation cranes are usually used in maintenance workshops and repair centers. They can lift heavy equipment and machinery, providing space for maintenance personnel to operate. They can also shorten the downtime of equipment.

  • Food processing and pharmaceuticals

Workstation cranes are usually used in industries with high hygiene requirements. They are suitable for lifting and moving materials and equipment in food processing plants or pharmaceutical factories. They can reduce the risk of product contamination.

  • Automotive industry

In automotive manufacturing, workstation cranes are usually used for assembly lines. They can lift and position automotive components with high precision. They can also improve production efficiency.

  • Laboratories and research facilities

In laboratories and research facilities, workstation cranes are usually used for precision experiments and equipment maintenance. They can provide flexible lifting solutions for delicate instruments and equipment.

  • Aerospace and defense

In the aerospace and defense industries, workstation cranes are usually used for the assembly and maintenance of aircraft and other large-scale equipment. They can meet the strict requirements of precision and safety.

How to choose workstation cranes

When selecting a workstation crane for a specific application, it is important to take into account several important aspects of the crane that will directly affect its performance and productivity.

  • Consider the material handling needs

It is necessary to determine the types of loads that need to be handled and the weight range. Furthermore, knowing the size and shape of the load is also critical. Based on the above data, one can choose a workstation crane with an appropriate lifting capacity, span, and hoist/trolley configuration to ensure it can effectively handle the required loads.

  • Consider the workstation layout

The workstation crane needs to be well integrated into the overall layout of the workstation to ensure effective and efficient material handling. Consider the location and number of workstations, the space available for the crane, and the workflow patterns. Based on these factors, choose a workstation crane with an optimal span, height, and positioning to meet the specific needs of the workstation's material handling.

  • Consider the operation mode

Consider the frequency and duration of workstation crane use. For frequent and continuous use scenarios, it is essential to choose a workstation crane with ergonomic design, simple operation, and fatigue reduction. If occasional use is required, it is more critical to consider the ease of use and maintenance of the workstation crane to ensure that it can be operated safely and efficiently when needed.

  • Consider the safety features

Safety is paramount when selecting a workstation crane. Choose a crane with safety features such as overload protection, emergency stop buttons, and collision avoidance systems. Ensure that the crane is properly installed and maintained, and provide training for operators to ensure safe operation at the workstation.
