Multifunctional Excavator Grapple Introduction

Today, I would like to introduce to you popular attachments such as wood/rock/steel grapples for excavators. This is one of the more commonly used attachments for excavators in addition to quick couplers and breakers. It is also Jiangtu’s best-selling excavator attachment.

About JT Excavator Grapple

The wood grapple also called wood grab, is an attachment of the excavator, mainly used for loading and unloading miscellaneous wood, whole wood, sugar cane, cotton, reed, forage and various other materials. The wood grapple’s claws can be transformed for grabbing stones and large objects such as stones, steel, scrap metal, and sundries.

Jiangtu is the earliest excavator attachment manufacturer in China. After the research and development of our engineering team and market verification, our wood grapple has complete categories ranging from 1-40 tonne excavators through continuous innovation, which is suitable for various excavators and application scenarios at home and abroad.

The Types of Hydraulic Grapples

Jiangtu grapples mainly include two types, hydraulic type and mechanical type, hydraulic type has the rotating type and non-rotating type. Different bracket types can be selected as the customer’s excavator. Different claws type can be chosen according to different site working conditions.

With innovation and improvement, the multifunctional grapple integrates a variety of claws, can be flexibly chosen according to different working conditions, and can be switched at will. Flexible working for loading, and unloading timber, haystacks, steel, sleepers, stone sleepers, flagstones, roots, and various other materials. and various other materials.

Jiangtu grapples are well-known in domestic and international markets. The quality is reliable and durable, and 5-6 year old grabs are common. One year warranty, and 6 months replacement guarantee customers’ most comfortable choices.

The advantages and characteristics:

Materials

The Jiangtu grapples are made of high-quality materials, excellent workmanship, precise processing, and superb welding technology. The Jiangtu grapples made of hardened and wear-resistant plates, which are purchased from domestic high-quality plate manufacturers and can withstand different working conditions.

The Claws

The claws are made of high-quality low-carbon steel and wear-resistant materials, which can prolong the service life; each claw contains an integrally formed T-shaped bushing, which is more reliable in performance compared to other factories’ products.

The Pins

All pins are made of high-quality alloy steel, heat-treated, with high surface hardness, wear resistance and bending resistance; all pins have better surface finish and tighter fit clearance after grinding treatment.

The Cylinder

The cylinder is equipped with a USA SUN brand balance valve to make the cylinder move smoothly and prevent the grapple from opening due to the oil pipe bursting; it is equipped with the M+S motor imported from Bulgaria/the Parker motor imported from the United States. The motor is equipped with a brake block with USA SUN brand double balance valves and double relief valves to reduce the impact during rotation and start or stop, and open smoothly

Structure Optimized

The optimized design of the structure meets the requirements of lightweight and high grabbing efficiency; the buffer design of the cylinder, silent operation, reduces the impact of extreme positions; the design of the special-shaped streamlined safety guard of the cylinder is added to facilitate the smooth insertion of the claws into different material piles while protecting the cylinder, balance valve and oil pipe from damage during working; the limit block protects the cylinder from impact and prolongs the service life.

The Function

In terms of function, it can rotate 360° clockwise and counterclockwise, with a three-second rotation cycle, which can realize flexible grasping in all directions. Different types of adapter parts are matched with kinds of grapples, and multi-functional grapple can also be chosen to meet the functional requirements of customers for grasping various materials.

EATON Handle

The imported EATON handle is used, which enhances the reliability of the operating system, prolongs the service life, and makes operation more comfortable.

Fittings and Pipelines

Fittings and pipelines meet the industry’s top standards, 4 times the impact resistance coefficient, high safety and reliability
