The latest SG80D hydraulic diaphragm wall grab from Shanghai Jintai is a cost-effective hydraulic grab newly developed according to market demand. The single-row rope long drum is used to reduce the loss of wire rope, and the hydraulic system is improved by optimizing the design of the upper chassis to increase the effective output power; the layout of the main engine parts is more reasonable, the heat dissipation is good, the maintenance is convenient, the construction efficiency is high, and the fuel consumption is low.

The bucket head is optimized by using discrete element and multi-body dynamics co-simulation technology, the bucket capacity is increased by 16%, and the grasping capacity is increased by 25%. The bucket tooth seat is made of forgings, which greatly improves the life of the bucket tooth seat.

The closing force of the opening and closing bucket oil cylinder is increased to 230T, which improves the ground breaking ability of the grab bucket in hard ground. ‍

Hydraulic winch system

• The unique coiling system, the power source is set up independently, avoids the interference with the main hydraulic circuit, and ensures that each actuator works synchronously;

• The pulling force of the hydraulic coil is constant, and the digging force is not affected by the groove depth;

• The reel coordination is further upgraded to better adapt to the stability of the trough and ensure synchronization with the bucket body ‍‍;

variable grab

• The grab is equipped with an 800 series variable grab, which can flexibly adjust the weight of the grab by increasing or decreasing the counterweight according to the ease of digging in the formation;

• The light load used in ordinary formations not only saves fuel and is environmentally friendly, but also increases the life of the wire rope;

• The bucket head has square bucket, arc bucket and large-capacity bucket configuration, and the configuration is flexible;

• Equipped with 12 push plate rectification system, the maximum thrust of the main cylinder is 2300KN; Patent: ZL201420553137.5;
