10 Ton Grab Overhead Crane Kits Sales & Service in Indonesia

Project Overview

DQCRANES successfully designed and delivered three custom grab overhead crane kits to a waste treatment plant in Indonesia. The client required robust, corrosion-resistant cranes to handle bulk waste materials, including municipal solid waste and recyclables. The grab bucket eot cranes were engineered for a 24-meter span and 17-meter lifting height, with a 10-ton lifting capacity. Notably, the client sourced the main girders locally, so DQCRANES provided the complete crane system, excluding the girders, ensuring seamless integration with the plant’s existing infrastructure.

Client Requirements

Application: Handling, sorting, and transferring waste in a high-corrosion environment.

Key Specifications

• Span: 24m (to cover multiple processing zones).
• Lifting height: 17m (to accommodate deep waste pits and storage bays).
• Load capacity: 10 tons.
• Exclusions: Main girders (client reused existing support structures).

Critical Needs

• Corrosion-resistant components for humid, chemically aggressive environments.
• Radio remote control for operator safety and flexibility.

Solution Provided by DQCRANES

DQCRANES delivered three double girder grab overhead crane kits, optimized for waste handling. The kits included:

Hoist and Trolley System:

• Robust winch hoist mechanism with a lifting speed of 8.7 m/min and traveling speed of 25.5 m/min for precise control.
• Winch Trolley equipped with anti-sway technology to stabilize loads during transfer.

Custom Grab Unit:

• Electro-hydraulic grab designed for bulk waste (0.5-1.0t/m³).
• Anti-corrosion coating (hot-dip galvanized) and hardened steel teeth for durability.

End Carriages and Runway Systems:

• Machined wheels and rails compatible with the client’s existing girders.
• Buffers and limit switches for safe trolley movement.

Power and Control Systems:

• IP55-rated electric components (motors, gearboxes) for dust/water resistance.
• Radio remote control system with emergency stop and overload protection.

Safety Features:

• Overload limiters, phase failure protection, and anti-collision sensors.
• Emergency backup power for mid-operation failures.

Environmental Adaptations

• Corrosion Protection: All steel components underwent sandblasting and epoxy-polyurethane coating. Stainless steel bolts were used in high-moisture areas.
• Tropical Climate Resilience: Motors and electricals rated for 40°C ambient temperature and 90% humidity.
• Dustproofing: Enclosed gearboxes and IP55-rated electrical panels to withstand airborne particulates.

Electrohydraulic Grab vs Mechanical Grab

Electrohydraulic Grab 

• Higher control of the working performance.
• Less weight of the crab and consequently of the crane, for the same capacity.
• Less cost of the grab crane as a consequence of the above mentioned.
• More simple electric control gear, and consequently cheaper.
• Less lateral losses.
• Higher worn in case of waste fire in the pit.
• Possibility of coupling worn due to bumps during the operation.
• More sensible elements due to the type of the pressurization filter and the oil
• filter application.
• Maintenance requirement for holding eye.
• Better filling rate due to better nailing into the waste mass.
• Shorter orange peel grab’s replacement times.
• Less height level.

Mechanical Grab

• As a general rule, higher opening and closing speed.
• Less maintenance of the proper orange peel grab or clamshell grab.
• Requires a frequent closing rope replacement in the hook block.
• Since the orange peel grab works quite inclined over the irregular surface, it can affect the rope systems.

Delivery and Support

• Kit Components: Shipped in modular sections for easy assembly.
• Installation: DQCRANES provided 3D assembly diagrams and video guides. Arrange for our technicians to assemble the cranes on-site.
• Training: On-site operator and maintenance training.
• Documentation: Compliance certificates, load test reports, and operation/installation manuals.

Result

• DQCRANES conducted a virtual site survey to verify girder dimensions and alignment. Custom end carriages ensured compatibility.
• Pre-tested modular components reduced on-site assembly time to 10 days per crane.
• The grab bucket cranes increased waste processing throughput by 30%, reducing manual handling.
• Zero downtime was reported in the first six months post-installation.

Client Feedback

The waste treatment plant praised DQCRANES’ flexibility in omitting girders and providing corrosion-resistant solutions tailored to tropical conditions.

Overhead Cranes for Garbage Handling

Overhead cranes play a crucial role in waste management operations, particularly in facilities where large volumes of garbage need to be handled efficiently and safely. DQCRANES offers garbage cranes designed to streamline moving, sorting, and disposing of waste materials, ensuring optimal productivity and environmental compliance. Below are some of the main types of overhead cranes commonly applied for garbage handling:

• Grab Bucket Overhead Cranes  

Grab bucket overhead cranes are widely used in waste management facilities due to their ability to efficiently handle loose and bulky materials. Equipped with a hydraulic or mechanical grab bucket, these cranes can lift and transport large amounts of garbage with precision. They are particularly effective in waste incineration plants, where garbage needs to be fed into incinerators or storage pits. The grab bucket design allows operators to scoop up waste materials quickly, minimizing downtime and improving operational efficiency.

• Double Girder Overhead Cranes 

Double girder overhead cranes are robust systems designed for heavy-duty applications. In garbage handling operations, these cranes are often used to move large containers or bins filled with waste. Their high load capacity and stable design make them ideal for handling substantial volumes of garbage, especially in industrial waste processing plants. Additionally, double girder cranes can be equipped with specialized attachments, such as magnets or grapples, to accommodate different types of waste materials.

• Semi-Automated Overhead Cranes

Semi-automated overhead cranes are increasingly popular in modern waste management facilities due to their ability to enhance operational efficiency while reducing labor costs. These cranes integrate automation technology to perform repetitive tasks such as loading and unloading garbage with minimal human intervention. They are particularly useful in facilities where waste needs to be sorted or processed systematically. Operators can control these cranes remotely, ensuring precision and safety during operations.

• Waste-to-Energy Facility Cranes  

In waste-to-energy plants, specialized overhead cranes are used to manage garbage that serves as fuel for energy production. These cranes are typically equipped with high-performance grab buckets or claws designed to handle mixed waste materials efficiently. Their role is critical in ensuring a consistent feed of garbage into the incineration or gasification units, contributing to the overall energy generation process.
