20 টন ওভারহেড ক্রেন: একক বনাম. ডাবল Girde দাম

20 টন একক গার্ডার বনাম. Double Girder Bridge Cranes

The primary distinction in 20-ton overhead cranes is between single girder and double girder designs. The choice depends on your application’s specific requirements for frequency, স্প্যান, and duty cycle.

20 টন একক গার্ডার ওভারহেড ক্রেন

A single girder crane features one main beam (গার্ডার) upon which the hoist and trolley travel. The hoist is typically mounted under the girder.

জন্য সেরা: Applications with lighter duty cycles, shorter spans (সাধারণত পর্যন্ত 30 মিটার), and where cost-effectiveness is a primary concern.

Key Characteristics:

• 1. Lower Cost: Simpler design requires less material and fabrication, resulting in a lower initial investment.
• 2. Lighter Weight: Puts less stress on the building structure, which can be crucial for existing facilities.
• 3. Reduced Headroom: The hoist sits directly under the girder, requiring less vertical clearance (হেডরুম) than a comparable double girder crane. This is ideal for buildings with height restrictions.

Limitation: Generally not suitable for extremely heavy-duty, continuous (CIC – Continuous Intermittent Cycle) applications or very long spans.

20 টন ডাবল গার্ডার ওভারহেড ক্রেন

A double girder crane features two main beams that support a trolley that runs on top of the girders. The hoist is mounted on this trolley.

জন্য সেরা: Severe-duty applications, দীর্ঘ স্প্যান (ওভার 30 মিটার), উচ্চ শুল্ক চক্র (CIC), and situations requiring maximum hook height.

Key Characteristics:

• 1. Higher Capacity & স্থায়িত্ব: The dual-girder design offers superior strength and is built for intensive, ঘন ঘন ব্যবহার.
• 2. Greater Hook Height: Because the trolley runs on top of the girders, the crane provides a higher lift, maximizing the usable space below.
• 3. অতিরিক্ত বৈশিষ্ট্য: Can more easily accommodate auxiliary hoists, magnet packages, or other special lifting attachments.

Limitation: Higher initial cost and weight, and requires more headroom.

20 Ton Overhead Crane Price

Providing an exact price is impossible without specific project details. ক 20 ton overhead crane price is highly variable and depends on:

• 1. টাইপ: A single girder crane is significantly less expensive than a double girder crane.
• 2. স্প্যান: The distance between runways directly impacts the price (longer span = higher cost).
• 3. উত্তোলন উচ্চতা: Higher lift requirements increase the cost.
• 4. ডিউটি ​​চক্র: Cranes rated for severe-duty (ফেম / CMAA Class D or E) cost more than light-duty (Class A) ক্রেন.
• 5. নিয়ন্ত্রণ করে: Radio remote control adds cost compared to a standard pendant control.
• 6. Brand of Components: Using premium hoist brands (যেমন, Konecranes, Demag) increases the price.

Price Range: একটি মৌলিক 20 ton single girder overhead crane might start around $15,000 - $25,000, while a custom, large-span, double girder overhead crane can easily exceed $50,000 - $100,000+. Always request a detailed quotation from a supplier.

Delivery Lead Time for a WEIHUA 20 টন ওভারহেড ক্রেন

The delivery lead time for a WEIHUA 20 ton overhead crane is not a fixed number but depends on several key factors related to the project’s complexity and customization. সাধারনত, for a standard specification crane, the lead time ranges from 40 থেকে 60 কাজের দিন after the final order confirmation and receipt of down payment.

For more complex or heavily customized projects, the lead time can extend to 60-90 working days or more.

The following table breaks down the typical stages of the process and the factors that influence the timeline:

Key Factors That Directly Impact Your Delivery Time

• 1. Single Girder vs. ডাবল গার্ডার: ক 20 ton single girder overhead crane has a simpler design and is often faster to produce. ক 20 ton double girder overhead crane is more complex, requiring more engineering and manufacturing time.

• 2. Level of Customization: Standard cranes are delivered fastest. Customizations like:

  • Explosion-proof specifications
  • Special paint coatings (যেমন, for marine environments)
  • Unusual span or lifting height
  • Advanced control systems (যেমন, অটোমেশন, precision load positioning)
    will significantly increase the lead time.

• 3. অর্ডারের পরিমাণ: A single crane order will follow the standard timeline. A larger order for multiple cranes will naturally take longer, though there may be some efficiency gains.

• 4. Component Availability: WEIHUA manufactures many core components, which helps control the supply chain. তবে, if you specify third-party branded components, their lead time must be factored in.

20 Ton Overhead Crane FAQ

প্রশ্ন ১: Which is better for my workshop, a single or double girder 20 টন ওভারহেড ক্রেন?

ক: If your usage is occasional, spans are short, and budget is key, a single girder is likely sufficient. For daily, intensive use, long spans, or needing maximum hook height, a double girder is the better, more durable investment.

প্রশ্ন ২: What maintenance is required for a 20 টন ওভারহেড ক্রেন?

ক: Regular inspections are essential. Daily checks by the operator, periodic inspections by a supervisor (monthly/quarterly), and a full annual inspection by a qualified technician are recommended to ensure safety and longevity.

Selecting the right 20-ton lifting equipment is a strategic decision that impacts your operation’s safety, দক্ষতা, এবং উত্পাদনশীলতা.
