ZQ162/50A 型钻杆动力钳
本钳所具有的特点 This tong has following features：、
1、采用液气联合控制系统，增强了工作的可靠性；
This tong simplifies hydraulic system uses pneumatic and hydraulic united controlled system, enhancing the work reliability.
2、采用上下钳合体结构，避免了钻柱在大扭矩作用下弯曲的可能性，并防止钻柱在卡瓦中打滑；
Upper tong integrates with lower tong to avoid twisting drill pipe in big torque operation and to prevent it slipping in neck.
3、本钳采用轻便灵活的钳头浮动方案，使吊装大为简化；自动对中夹紧机构可保证新旧接头卡紧可靠；
This tong adopt flexible floating mechanism, making hoist simplified and automatically centered clippingmechanism can assure the their work reliability.
4、增强型的钳身和安全门，有效限制了大扭矩作业时钳头的变形；
Enhanced tong body and safety door restrain deformation at large torque with effectively.
5、钳头中独特的坡板与楔形块联接结构，装拆维护极为方便；
The connection of unique ramp and wedge block makes assembly and removal very convenient.
6、气胎离合器不停车换档机构，操作简便，扭矩与速度均能控制，正反方向都可产生最大扭矩和转速；
The pneumatic tyre clutch shifting without pause enable the torque and speed can be controlled conveniently. What's more, positive and negative direction all cangenerate maximum torque and speed.
7、可采用液压吊杆升降钳身高度，推进气缸移送钳身位置，不需人力位移钳体。
We can use hydraulic hanger to adjust the height of tong body and impel cylinder to regulate the positionwithoutlabor force.
