Hydraulic Rotating Grapple for Crane Pickup

Product Description

1.Introduction
The steel grabber material handling machine is a kind of scrap loading and unloading equipment. It can realize a variety of operation functions by changing the gripper material handling and working device. Therefore, it is also called a grabber, which is widely used in steel plants, smelters, ports, docks and scrap transfer. Special engineering machinery in the industry, equipped with different grippers (such as plum grab, shell grab, round grab, billet grab, hydraulic shear, hydraulic pliers, etc.) to meet different customer conditions for scrap, ore, coal The demand for bulk fertilizer and yellow sand loading and unloading.
1).Economical and reliable
Single pump constant power, dual pump cross power control, stable engine output;
Negative flow pump control method and good economy;
The hydraulic oil radiator and engine water cooler are cartridge-mounted, compact and efficient;
Hydraulic hoses and seals are fixed with imported products and have high reliability.
2).Reasonable design
The boom and the arm are hydraulically locked, and the impact resistance is good, and both of them realize the double pump confluence, the stick regeneration, the multi-motion composite, and the work is stable;
Two speeds of walking speed are selected to achieve two speeds to meet different working conditions;
Upper arm brake for walking and swinging mechanism, hydraulic opening, good safety;
Flexible configuration according to different grades of users;
The power system, hydraulic system and working device can be freely and flexibly configured according to user requirements;
The working device adopts the structure of "straight moving arm and curved stick", and is equipped with electric suction cup and lifting driver's cab;
3).High efficiency and environmental protection
Simple operation, convenient maintenance and safe and reliable performance;
Environmental protection, energy saving, low noise and long service life;
The far-infrared remote control system can realize long-distance operation; the crawler type traveling device has small grounding pressure, stable walking and flexible steering.
2.Advantage
1).The engine air filter is double-filtered, which can well cope with the problem of large dust on the scrap picking operation site. Especially in a closed working environment indoors, the dust concentration is greater. The dual filtration system increases engine efficiency and extends service life.
2).The cab can choose height adjustable type or fixed type with different height.The cabin is shockproof and soundproof type.It has wide view and equipped with air conditioning and audio, air seats, safe and comfortable.
3).Power system, hydraulic system and grabbing implements can be customerized according to different working size and work requirement.
4).Standard central lubrication make daily maintenance easy.
5).Diesel and electric hybrid drive can be driven by both internal combustion engine and electric motor drive.
Driven by electric motor, it has low maintenance cost, no pollution and low failure rate. 4. Motor operation is one third of the cost of internal combustion engine operation.
6).Original imported hydraulic system, exclusive electronic control system, the perfect integration of mechanical, electric and hydraulic integration.
7).widened and extended "X" frame, standard with 800mm aluminum plate, strong stability, to ensure the efficient operation of the whole machine.
8).It adopts high-strength wear-resistant steel, shell-type grab, plum grab, electromagnetic sucker and other accessories to flexibly switch, and can be customized according to working conditions.
9).Original imported hose, steel wire surround, to prevent oil leakage, high reliability.
10).Equipped with a hydraulic oil strong air heat sink to ensure that the hydraulic oil temperature rise of the equipment does not exceed 80 °C. Effectively extend the life of hydraulic seals.
