Oil Pump
The oil pump we used is from the brand of REXROTH or VICKERS to ensure the high performance. The oil pump has two types for you to choose from: rotary vane pump and plunger pump. The rotary vane pump features compact structure, smooth operation, proportioned flow, and makes little noise. The plunger pump features high precision, good sealing performance, high work stress. In addition, according to the working condition, Yong Sheng can also provides suitable double pump.

Lubrication Oil Tank
The lubrication oil tank is designed for lubrication the cutterhead automatically, due to its simple structure the maintenance is very easy.

Daily-use Oil Tank

Audible and Visual Alarm
The audible and visual alarm can protect the safety of operators and ensure the smooth operation of equipment. It is connected with sensors arranged in certain part of the dredger to receive operation signals in time.
Once the equipment failure is detected, the alarm will automatically raise an alarm to let operators deal with the problem immediately, so as to meet the requirements of protecting both personnel and equipment.
