The hydraulic system is relatively mature, compact, three anti-ideal ideal, the hydraulic pump is placed at the proximal end, the moving bucket is at the far end, the lifting force can be very large, but the power loss is also large, the hydraulic oil leaks and the overall failure, the hose routing is complicated And so on, the whole machine needs circuit and hydraulic two-way system. The electric structure is simple and it belongs to a distributed layout. It can provide only electric power. After a single motor failure, it does not affect the whole, the cost is low, and the parts are easier to buy and replace. The problem is that the motor power density or power per unit mass is lower than that of the hydraulic system. It also needs the gear and worm to amplify the torque, and the DC transmission loss is large. The AC frequency conversion is also not easy to realize and is not waterproof.
In addition, both of them face the problem of low battery capacity and output power, so some products use oil machines instead.
