摘要
从技术的先进性和经济的可行性出发,研制的TJ12/50A(B)型轮式通井机采用整体式专用底盘,辅以工程机械用转向桥和大轮胎,使整机具有良好的运移性和越野性;自携作业井架,减少了修井作业中的辅助配套设备,降低了劳动强度;采用柔性传动部件—液力变矩器和液力换档变速箱,使传动系统的可靠性大为提高。
Considering the advancement of technology and feasibility of economy, model TJ12/50A(B) wheeled tractor hoists were developed. Specially designed for the units, the monoblock type special chassi is driven by off the-road wheels and wide base tyres. Equipped with flexible transmission components-hydraulic torque converters and hydraulic gearshift boxes, the wheeled tractor hoists are also provided with masts.
