LDZ Grab Bucket Electric Single Girder Overhead Crane

Bulk-material handling where the required capacity and cycle can be satisfied by a single-girder grab crane and the buyer wants a lower-cost alternative to a grab double-girder crane.

The LDZ is for buyers who need to move bulk material with a grab but do not automatically need the heavier structure and cost of a double-girder grab crane. Its source-defined configuration uses two hoists with a four-rope grab to support stable and efficient bulk handling.

Correct selection depends on more than crane tonnage. Material bulk density, required grab volume, filling factor, cycle rate, lifting height and working duty determine whether the LDZ single-girder platform is suitable.

Product Overview

The LDZ grab electric single-girder crane is an improved design based on the electric single-girder crane.

The lifting mechanism uses electric hoists and the load handling device is a grab bucket.

The source specifies a dual-hoist lifting mechanism paired with a four-rope grab.

For a new procurement project, the final configuration should be selected from the actual suspended load, span, lifting height, runway condition, operating cycle, working environment and applicable project requirements. Parameters not published on the source page are therefore treated as project-specific rather than guessed.

Why Choose LDZ Grab Bucket Single Girder Crane?

Purpose-Built Grab Handling

The load handling device is a grab bucket rather than a hook.

Dual-Hoist / Four-Rope Arrangement

The source specifies two hoists paired with a four-rope grab for stable bulk-material handling.

Reliable Drive Components

The source highlights forged wheels and Nanjing special drives.

Lower Purchase Cost

The source states that procurement cost is lower than a grab double-girder crane.

Simpler Lifecycle Maintenance

The source describes later maintenance as simple with lower comprehensive use cost.

Application Scenarios

How to Select the Right LDZ Grab Bucket Single Girder Crane

1. Identify the Bulk Material

Provide material name, bulk density, particle size, moisture / flow behavior and any special hazards.

2. Define Required Throughput

State tonnes per hour or required cycles per hour so grab volume and crane duty can be checked.

3. Confirm Grab Weight and Volume

The crane's suspended load includes the grab itself plus the material inside it.

4. Confirm Lifting Height and Travel Distances

These directly affect cycle time and throughput.

5. Decide Single vs Double Girder

If capacity, duty or cycle rate exceeds the efficient range of the single-girder system, a grab double-girder crane should be evaluated.

Safety & Control: What Buyers Should Confirm

• Rated capacity and overload-protection requirements
• Upper / lower travel and hoisting limits appropriate to the application
• Emergency-stop and braking requirements
• Electrical protection and site power conditions
• Operator control method and visibility
• Any project-specific anti-collision, warning, environmental or special safety requirement

Installation & Maintenance

Before installation, confirm runway span, rail or runway-beam condition, elevation, straightness, power supply, access for erection and the lifting plan for the crane structure. Retrofit projects should also provide available building and runway information for structural review.

Maintenance requirements should follow the final supplied configuration and manual. Routine work normally includes inspection of the lifting mechanism, brakes, rope or chain where applicable, wheels, drives, fasteners, limits and electrical protection, with lubrication and replacement intervals defined by the actual product configuration and duty.

Frequently Asked Questions

How does the LDZ grab crane work?

The source specifies two electric hoists used with a four-rope grab, allowing the crane to lift and control the grab for bulk-material pickup and discharge.

Is LDZ cheaper than a double-girder grab crane?

The source states that its procurement cost is lower than a grab double-girder crane.

What material data do you need for quotation?

Bulk density is essential, together with particle size, required throughput and any flow or environmental characteristics that affect grab selection.

How is crane capacity calculated with a grab?

The suspended load includes the grab self-weight plus the material carried in the grab.

When should I choose a double-girder grab crane instead?

Evaluate double girder when required capacity, working duty, cycle rate, span or throughput becomes too demanding for the single-girder layout.
