Types of Precast Yard Gantry Cranes

A precast yard gantry crane is a large lifting machine that moves horizontally by rails or other support systems. It is used for lifting and moving heavy precast concrete products and other materials in outdoor yards or open spaces. Here are some common types of precast yard gantry cranes:

• Roller Gantry Crane

  Typically employed in areas with level or moderately inclined flooring, the roller gantry crane is a versatile device utilized for the horizontal movement of goods. It employs three sets of wheels or rollers mounted to an upright frame for the lateral movement along a beam.

• Modular Gantry Crane

  Modular gantry cranes are detached lifting devices that may be easily moved from one location to another. This is due to their unique design, which comprises of one or more modular units that may be assembled or unassembled as needed. These units are often lightweight but strong, allowing for convenient movement and transportation.

• Pneumatic Gantry Crane

  A pneumatic gantry crane is an example of a portable gantry crane with a contemporary touch in technology. It makes use of air pressure to empower its movements and lifting mechanisms. This offers it a number of benefits, such as enabling the handling of heavy loads with light energy requirements and improving its flexibility of use in locations where pressurized air is accessible.

• Emergency Gantry Crane

  When there is an urgent need to swiftly move heavy equipment or materials, a gantry emergency crane is called into action. Such might take the shape of a mobile truck fitted with a gantry system or a crane that has been built to safely and efficiently lift heavy loads.

Specification and maintenance of precast yard gantry cranes

Specifications of the precast yard gantry crane will mostly depend on the yard size and the type of crane chosen. Here are some specifications to look at:

• Product dimensions: The height, length, width, and weight of the crane will determine how much it can carry. Taller cranes can lift heavier weights. A longer span will mean lifting wider loads. An average precast gantry crane can have a height of 6m-12m and span of 12m-30m. The weight will depend on the material used to build it.
• Control system: Cranes can have different kinds of control systems. It can be ground control (wired) or remote control (wireless). A crane managed from the ground will have a system of ropes and pulleys to move the load. Remote-controlled cranes will have a box with buttons that a person can carry and use from different distances.
• Wheel size and pressure: These are important for the crane's stability and movement. The wheel pressure affects load distribution. A precast yard crane needs to have its pressure calculated to ensure it can safely and easily move heavy concrete items on the grounds where it is used.
• Working power: A precast yard crane could be battery-powered or run by a diesel engine. The amount of fuel it uses and how long it can run on one charge or tank is important.
• Design type: A crane design construction will determine how it operates. For instance, A double girder design will have two main beams at the top, while a single girder will have one main beam.

Maintenance

Cranes need periodic inspections and regular maintenance to ensure they function efficiently for a long time. Some parts of the crane may need to be replaced or repaired from time to time, but the key to safety is to inspect it regularly.

Every day before operating a precast gantry crane, it's a good idea to do a walk-around inspection. This helps in spotting any minor issues before they become major ones. Daily checks should include:

• Looking at all structural parts of the crane to see if anything is damaged.
• Ensuring there are no oil leaks from the equipment.
• Checking all stop buttons, limit switches, and emergency switch functions were done right.
• Looking at the hook and other attachments to see if they are worn out or damaged.

Monthly inspections by a qualified technician should be done to carry out thorough checks on important crane parts. Some checked areas include the electrical system, brakes, tires, anchor bolts, gearbox, wheels, pulleys, and hooks, among other parts.

Technicians usually follow maintenance and inspection manuals provided by crane manufacturers. But some general maintenance tips include:

• Lubrication: Lubricate all moving parts as recommended by the manufacturer to reduce wear and tear.
• Clean: Remove dust and dirt from the crane parts to prevent clogging and damage.
• Storage: Always store the crane in a dry and sheltered area so that it is protected from harsh weather conditions.

Scenarios

Precast gantry cranes are widely used in construction, logistics, and ports. In these industries, they are the go-to machines for lifting and transporting heavy materials and products.

• Construction of precast concrete elements:

  In construction, precast yard gantry cranes are commonly used for the lifting and transportation of onsite precast concrete elements. They can easily and efficiently lift heavy precast concrete components like beams, panels, columns, and more. They are a great machine for reducing the need for multiple lifts, thereby minimizing the difficulty of handling operations.

• Logistics and warehouse operations:

  In the logistics and warehousing aspect, precast yard gantry cranes can be used to load and unload heavy goods from containers to trucks or other modes of transport. They can also be used to stack heavy goods onto shelves or retrieve them from shelves. With its ability to move across a rail or ground stored in facilities, a precast gantry crane equips warehouses with the means to respond to various logistics operations efficiently.

How to Choose Precast Yard Gantry Cranes

• Needs Assessment:

  When looking at available options, it's important for businesses to first look at their own needs. Consider what types of precast products are made and how heavy and big those components are. Also, estimate the highest lifting capacity and span. Take a close look at the yard layout as well, including any height restrictions. By carefully considering specific requirements, it's more likely to select a gantry crane that perfectly matches operational needs.

• Mobility and Flexibility:

  Precast yards often have different areas where products are made, cured, and stored. Choosing a gantry crane with features that allow for easy movement is important. Do the wheels roll smoothly on multiple surfaces? Is the weight manageable for safe manual pushing or pulling? If powered travel is an option, is the capacity and battery life sufficient? Can the layout accommodate rail tracks? Addressing these questions helps ensure the crane can easily reach components wherever they are located within the yard.

• Assistive Technologies:

  Many gantry cranes used in precast yards now have helpful technologies that assist operators during lifts. These may include load sensing systems to detect and display weight, ensuring that loads are not exceeding crane capacity. Anti-sway functions are another feature, stabilizing and controlling the motion of lifting components to prevent swinging during movement. Additionally, remote controls allow the operator to maneuver the crane from a comfortable standing position, rather than from a fixed location. These technologies can greatly increase safety and operational efficiency.

• Safety Features:

  Operator safety is a central concern. Ensure the chosen gantry has important protective features. A comprehensive barrier system prevents access to dangerous areas. Emergency stop buttons allow operators to quickly halt operation if needed. Durable construction provides protection from environmental hazards. Cranes should also be designed to reduce the risk of worker falls. These elements combine to help keep those using the gantry secure while on the job.
