Introduction
DQCRANES, a global leader in material handling solutions, recently designed and exported a 3 ton A frame
gantry crane to a plastic manufacturing company in Malaysia. The crane was engineered to streamline the client’s plastic mold-handling operations, emphasizing portability, precision, and safety.
Client Background
The client, a Kuala Lumpur-based plastic injection molding manufacturer, produces automotive and consumer goods components. Their existing setup relied on stationary
overhead cranes, causing bottlenecks when moving heavy molds (1–3 tons) across multiple workstations. The need for a mobile, space-efficient solution to improve workflow efficiency drove their search for a specialized gantry crane.
Project Requirements
- Capacity: 3 tons (to handle molds up to 2.8 tons with safety margin).
- Mobility: Portable design for repositioning across the factory floor.
- Precision Handling: Plastic molds are high-value, delicate components requiring stable and jerk-free lifting.
- Workspace Flexibility: The crane needed to be portable to accommodate multiple workstations in a compact facility.
- Durability: Resistance to humidity and dust in Malaysia’s tropical climate.
DQCRANES delivered a fixed height gantry crane tailored for portability and stability:
- A-Frame Design: Triangular structure for optimal load distribution and space efficiency, hot-rolled steel (Q235B).
- Span: 3.5 meters (to bridge production equipment and worktables).
- Lifting Height: 3.5 meters (sufficient for mold placement in presses).
- Hoist: electric chain hoist for precision; motorized trolley for effortless horizontal movement.
- Mobility: Heavy-duty locking casters (2 fixed, 2 swivel with brakes) for portability.
- Control: Pendant control with emergency stop.
- Safety Features: Overload limiter, upper/lower limit switches, and IP54-rated components.
- Power Supply: 415V/50Hz (3-phase), compliant with Malaysian standards.
Key Features and Benefits
The a frame gantry crane is equipped with advanced safety features, including overload protection and emergency stop functions. These features significantly reduce the risk of accidents during lifting operations. By replacing manual handling with mechanized lifting, the solution also mitigates ergonomic risks for workers.
The motorized trolley and electric chain hoist work in tandem to provide seamless lifting and movement of plastic molds. This reduces downtime and increases productivity by enabling faster and more precise material handling.
The portable design of the fixed height gantry crane allows it to be moved to different locations within the facility as needed. This flexibility is particularly beneficial for dynamic manufacturing environments where operational layouts may change over time.
- Durability and Reliability
Constructed from high-quality materials, the portable a frame gantry is built to withstand rigorous industrial use. Its robust design ensures long-term reliability, minimizing maintenance requirements and downtime.
Manufacturing & Exporting
- Production: The 3 ton mobile a frame gantry was manufactured in 4 weeks, followed by rigorous load testing (125% of SWL) and CE certification.
- Shipping & Delivery: Disassembled components were packed in seaworthy crates and shipped via sea freight to Port Klang.
- Installation: DQCRANES provided detailed assembly manuals and video guides. Local technicians assembled the crane in 6 hours.
- After-Sales: 12-month warranty; 24/7 remote support.
Results & Benefits
- Efficiency: Reduced mold setup time by 40%, enabling faster production cycles.
- Safety: Eliminated manual handling risks; zero incidents reported post-installation.
- Portability: The crane’s lightweight design allowed movement across 5 workstations.
- Cost Savings: Reduced reliance on external crane rentals, saving ~MYR 15,000 annually.
Client Feedback
“The a frame crane transformed our workflow. We now move molds between presses in minutes, not hours. The precision and safety features are exceptional.”— Production Manager, Client Company
How to Buy A Suitable Portable Gantry Crane?
Choosing a suitable portable gantry crane from DQCRANES involves a systematic evaluation of your needs and the crane's specifications. Here's a structured guide to help you make an informed decision:
Determine Load Requirements
- Lifting Capacity: Calculate the maximum weight you need to lift, including any attachments (e.g., slings, hooks). Choose a crane with a capacity 20-25% higher than your maximum load to ensure safety and longevity.
- Load Characteristics: Consider the load's shape, size, and center of gravity. Irregular or hazardous loads may require specialized features like anti-sway mechanisms or explosion-proof options.
Assess Workspace Dimensions
- Span (Width): Measure the distance between the crane legs to ensure it fits your workspace and covers the lifting area. Adjustable spans offer flexibility for varying tasks.
- Lifting Height: Ensure the vertical clearance accommodates both the load height and lifting equipment (e.g., hoist). Check for adjustable height options if your needs vary.
Evaluate Portability Needs
- Mobility Features: Opt for models with heavy-duty casters (swivel or fixed) for easy movement. Locking mechanisms enhance stability during operations.
- Weight and Material: Aluminum cranes are lightweight and corrosion-resistant for frequent relocation; steel cranes offer higher durability and capacity for industrial settings.
- Assembly: Prioritize quick-disassembly designs if space storage or transport is a concern.
Consider the Operating Environment
- Indoor vs. Outdoor Use: Outdoor environments may require weather-resistant coatings or galvanized steel to withstand elements.
- Floor Conditions: Ensure the crane’s wheels/casters are compatible with your floor surface (e.g., smooth casters for concrete, rubber for delicate floors).
Adjustability and Customization
- Modular Designs: Look for cranes with adjustable spans and heights to adapt to different tasks.
- Accessories: Confirm compatibility with hoists, trolleys, or remote controls. DQCRANES also offers customizations like rotating bases or extended beams.
Safety and Support
- Safety Features: Verify overload protection, emergency stops, and secure locking pins. Ensure compliance with standards like FEM/DIN or CE.
- Operator Training: Ensure your team is trained to use the crane safely, especially for motorized or complex systems.
- Warranty and Support: Check warranty terms and availability of technical support or spare parts.
