The grab crane supports move, rotate and lift adjustment. Your workers can master the operation quickly with short training, saving your skill training costs.
Each grab crane is installed with safety protection devices, such as overload limit, emergency stop and anti-collision features. It can prevent overloading operations and accidents, making your daily production safe.
With advanced control systems, our grab crane can achieve accurate positioning, opening and closing the grab bucket. It helps reduce material spillage and improves your workplace safety.
The electrical component delivers stable performance, and the motor runs steadily with low energy consumption. It helps you cut long-term power costs and is suited for mass material handling.
Our grab crane can work normally in high temperatures, dust and humid environments. Its surface is coated with anti-rust paint to slow aging and corrosion, lowering your maintenance frequency.
It features automatic material retrieval, weighing, and PLC systems that adjust gripping forces and pathing according to the weight and shape of the load. This improves efficiency and reduces manual labor.
Accelerate Your Project Progress
Whether you are dealing with mineral aggregate, domestic garbage, or industrial waste, our equipped grab bucket can feed, transfer, and unload at high speed, replacing slow and costly labor. This stable equipment can shorten working cycles and help you receive more orders, thereby boosting your productivity.
Reliable and Durable
We use high-strength steel and advanced welding craft to construct grab cranes. Meanwhile, paired anti-sway systems maintain stability during swift movements. Therefore, you can use it inÂ
heavy-load jobs.Â
Moreover, the machine body is sprayed with multi-layer paint to isolate dust, moisture and chemical erosion on site. Strict factory load testing is carried out before delivery to ensure long-term value for your factory.
Considerable Customization Service
Our grab crane supports personalized customization. Whether indoor or outdoor, it can be tailored to your site layout and material characteristics. You can freely choose lifting tonnage, working range, travelling mode and grab bucket type. This will help you enhance the client’s satisfaction and bring more repeat customers.
Typical Applications of Grab Crane
You’ll often see the grab crane in handling bulk cargo such as coal, ore and grain at ports. It helps speed up loading, unloading, and storage. No matter what the weather is like, it can operate stably and improve logistics efficiency.
It is perfectly used for grabbing and sorting domestic garbage, industrial waste and recyclable materials. And the sealed grab bucket prevents material leakage and odor overflow, helping you comply with environmental production standards.Â
The grab crane can assist you in grabbing and stacking sand, stone and other raw materials. It is easy to operate and adapt to different construction layouts and material volumes, relieving your carrying pressure and speeding up jobs.
Its robust structure and wear-resistant grab buckets are enough for coal yards and mineral processing plants. And it runs well even on bumpy roads, and its accessories hold up under stress. So, it will lower downtime and your repair costs.
With gentle material handling, our grab cran can be used for grain, feed and crop. You don’t need to worry about grain damage and contamination during loading and unloading. It is beneficial to manage large amounts of grain and extend its storage life.
With anti-corrosion structural components, it can handle the chemical materials safely and efficiently. Moreover, the closed bucket reduces dust leakage and prevents harmful odor from spreading, thereby keeping a cleaner working environment.

Under normal conditions, the grab crane can last 10-15 years. If you maintain it regularly, its service life will be extended. Remember that you need to protect it from overload.
When grabbing powdery materials, it is recommended to use a sealed grab bucket and slow the lifting and moving speed to avoid dust spread. At the same time, you should close the bucket before lifting, and unload gently to keep dust down.
Cabin control gives you a direct view and is suitable for long and complex working conditions. On the other hand, remote control is flexible and convenient, letting you work from a distance. It is ideal for small and simple grabbing operations.Â
Yes, it performs well from -20℃ to +45℃. We use electrical components with cold-resistant jackets and low-temp hydraulic oil. Also, the structural parts are treated to prevent freezing or rust.
You need to lubricate the rotating and walking parts, check the bucket and connecting bolts’ status. Clean dust from electronics, and replace vulnerable parts on time. These simple daily care can greatly extend the crane life.
Types of Grab BucketsÂ
Mechanical Clamshell Grab Bucket
It relies on mechanical transmission to open and close. Due to its simple structure, you don’t need to spend too much time and effort on maintenance. It works well for dry materials like coal, grain, sand, and gravel. Suitable for a factory with limited budget.
But its gripping power and sealing aren’t great, so it is difficult to deal with sludge or any sticky material.Â
Hydraulic Grab Bucket
Driven by hydraulic pressure, it can tightly grasp wet sludge and mineral residue without leakage. It delivers high-speed handling, and you can use it in high-intensity projects.
However, you should pay more and regularly change the oil and sealing rings.Â
Electric Motor Grab Bucket
It is driven by the motor and reducer, and can be easily connected with crane electrical systems.
Thanks to its low noise, you can put it in the enclosed workshops for a long time. Meanwhile, it features moderate gab force and can help you save a lot of operational costs. Unfortunately, it’s also less effective on ultra-sticky or heavy corrosive materials.
Electro-Hydraulic Grab Bucket
The hybrid grab bucket combines electric control and hydraulic drive, delivering precise control, strong overload resistance and powerful grip force. It serves as a versatile grab solution and handles mixed materials, sticky materials, garbage and irregular bulk goods.Â
Compared with hydraulic grab buckets, it requires lower maintenance expenses, facilitating you to wire and install.Â
Orange Peel Grab Bucket
With multiple claws, it provides you with strong clamping force and wide grabbing range. It is mainly used for complex and irregular materials, such as steel scrap, wood and waste metal. But you’d better not handle powdery bulk materials. You can match it with jib and tower grab crane.
How to Choose the Right Grab Crane?
Material Type
You should consider properties of the materials, including dryness, viscosity, size and density. For dry and loose bulk material, such as coal and grain, it’s best to select mechanical grab buckets. But for wet and sticky material, the hydraulic grab bucket with strong sealing is preferred. Also, the orange peel grab is ideal for irregular block materials like crap steel.
Working Site
You need to measure the on-site span, lifting height and walking range. If you have a narrow working space, the overhead or jib grab crane is good. For large open yards, ports and construction sites, the gantry grab crane can help you maximize the use of on-site space.
Daily Output
Generally, for daily production of less than 500 tons, an A3-level grab crane is recommended.Â
A4-A5 level is suited for continuous operation with a daily output of 500-1000 tons. If you want to produce over 1000 tons in one day, A6-A7 heavy-duty grab cranes can meet your demand.
Budget
If you pursue low cost and mainly apply for regular industrial sites, then the mechanical grab crane is a good option for you. For demanding ports and chemical parks, you can upgrade to a hydraulic grab crane. Tell us your application and budget, and we can help you configure other functions.
