Case Study: 3 Ton Portable Gantry Crane for Spain Workshop
Case Study: 3 Ton Motorized Portable Gantry Crane for Sale in Spain
For Automobile Repair Shop — 3.5 m Span, 4.3 m Lifting Height, 220V 50Hz 3-Phase Power Supply
Project Overview
This project was completed for an automobile repair and service workshop in Spain, where the client needed a compact and easy-to-move lifting solution to handle heavy components like engines and gearboxes. The workshop operates on a 220V, 50Hz, 3-phase power supply, which is common in Spanish industrial facilities. The crane was specially designed to match their available power and workshop layout.
The selected model is a motorized portable gantry crane with a rated capacity of 3 tons, a span of 3.5 meters, and a lifting height of 4.3 meters. These dimensions make it practical for daily use inside repair bays without taking up too much space.
- The client runs a medium-sized garage handling car and light truck maintenance.
- The workshop has limited floor space and moderate ceiling height, which ruled out fixed overhead cranes.
- Heavy assemblies, such as engines, axles, and transmissions, need to be lifted regularly for repair and reinstallation.
- The workshop floor is smooth concrete, allowing motorized gantry movement between bays.
- Power sockets are distributed across the bays, making a 220V, 3-phase system ideal for plug-and-play use.
- Type: Motorized portable gantry crane with electric hoist and powered travel.
- Capacity: 3 tons — sufficient for typical engine and undercarriage handling tasks.
- Span: 3.5 m — wide enough to straddle cars or light trucks in standard service bays.
- Lifting Height: 4.3 m — provides clearance for lifting engines directly out of the vehicle and placing them on stands.
- Mobility: Equipped with polyurethane wheels for smooth and floor-friendly movement, even under load.
Spain's workshop electricity typically uses 220V 50Hz 3-phase, which is slightly different from the 380V industrial power seen in larger plants.
To match this setup, the crane was built with:
- Customized motors and controls rated for 220V operation.
- Phase-loss and overload protection to keep the system safe during frequent starts and stops.
- Compact control box and plug connector, so the crane can be moved between power outlets without hard wiring.
- Energy-efficient drive system that runs steadily on standard shop circuits without tripping breakers.
During daily work, the 3-ton gantry crane is used for:
- Engine lifting: Removing or installing engines with precision and minimal manpower.
- Gearbox and axle handling: Aligning and positioning components under the vehicle.
- Vehicle body lifting: Supporting partial lifts during frame inspection or suspension replacement.
- Loading tasks: Moving heavy parts or tool sets delivered to the garage.
This setup allows mechanics to move the crane where it's needed, connect it to the nearest power outlet, and start lifting within minutes—no fixed runway or foundation required.
Client Background and Needs
The client operates a medium-sized automobile repair garage in Spain, servicing both passenger cars and light trucks. Their daily operations involve frequent handling of heavy components like engines, gearboxes, and suspensions. While the garage is busy and well-equipped, space is limited, making it tricky to work with large or fixed lifting equipment.
Mechanics often need to move heavy parts from one bay to another, so the workshop requires a lifting solution that is both mobile and reliable. The crane also needed to integrate seamlessly with the workshop’s existing 220V, 50Hz, 3-phase electrical system, without complicated rewiring or adapters.
Workshop Profile
- Medium-sized garage servicing cars and light trucks.
- Frequent lifting of heavy components like engines and gearboxes.
- Limited indoor space, requiring compact equipment.
Main Challenges
- Tight workspace layout and low ceiling height, restricting fixed crane installation.
- Need for easy movement between multiple repair bays.
- Ensuring full compatibility with the workshop’s 220V 3-phase power supply.
The client wanted a crane that could fit their space, work safely under the ceiling constraints, and connect directly to their electrical system. Mobility, ease of use, and stable lifting performance were top priorities.
Technical Solution
To meet the workshop’s requirements, we designed a motorized portable gantry crane that combines mobility, strength, and compatibility with local power conditions. The solution focuses on practical use in tight spaces, easy operation, and stable performance under Spain’s 220V, 50Hz, 3-phase electrical system.
Crane Configuration
The crane is built for daily workshop use, with features that make lifting and moving heavy components easy and safe.
- Type: Motorized portable gantry crane with electric hoist and powered travel, allowing the crane to move smoothly between bays without manual pushing.
- Structure: Steel frame with adjustable height and detachable legs, so it can be moved, stored, or fitted into different bays as needed.
- Mobility: Polyurethane casters provide quiet and smooth movement on concrete floors, minimizing floor wear and giving mechanics full control when positioning the crane.
This setup allows the crane to fit into tight spaces, handle loads safely, and be ready for use across multiple service areas without complicated installation.
Power Supply Design
Electric compatibility was a key consideration for the workshop. Spain’s standard 220V 50Hz 3-phase power meant the crane had to be carefully adapted for reliable and safe operation.
- Motor and control system were customized for 220V 3-phase input, ensuring full power without overloading circuits.
- Overload and phase-loss protection keeps both the crane and workshop safe, even during repeated lifts.
- Plug-and-play connection allows the crane to be moved easily between outlets without rewiring.
Advantages for the workshop:
- Energy-efficient motors reduce electricity consumption and heat generation.
- Simple maintenance, no complex rewiring or specialist technicians required.
- Stable lifting performance, even if the local voltage fluctuates slightly, giving mechanics predictable, safe operation every time.
This combination of practical structure and tailored power design makes the gantry crane perfect for daily automobile repair work, where space is limited and reliability is essential.
Application in the Automobile Repair Shop
The 3-ton motorized portable gantry crane has proven to be a reliable helper in everyday workshop tasks, handling heavy components with ease while fitting into the garage’s limited space. Its design allows mechanics to work efficiently, safely, and without unnecessary strain.
Typical Lifting Tasks
In a busy repair shop, the crane is used for a variety of lifting and moving operations:
- Engine removal and installation: Lifting engines out of vehicles or placing rebuilt engines back in, with precise control.
