A planar controllable slippage type wood forklift with a multi-unit connection rod driving function comprises a multi-unit connection rod driving mechanism, a movable arm lifting mechanism, a fork bucket control mechanism and the like. Under control of a computer, the multi-unit connection rod driving mechanism achieves driving of multiple small-power motors and high-power and high-torque power output, and meets the power requirement of high-load operation of the slippage type wood forklift. A hydraulic cylinder is applied to the configuration design of the wood forklift as a connection rod on the basis of the Pascal principle, the problem that in the prior art, stress on two driving chains for lifting a movable arm is unbalanced is effectively solved, and the bearing stability is improved. The slippage type wood forklift not only has the characteristics of being high in transmission efficiency, high in response speed, high in motion precision, good in controllability, capable of saving energy, environmentally friendly and the like as a controllable mechanism, but also has better bearing performance and shock resistance through introduction of the multi-unit connection rod driving mechanism and a hydraulic element, can achieve the overload protection function easily and has great engineering application prospects and development potential.

A simple high-load wood forklift with a multi-unit connection rod driving function comprises a multi-unit connection rod driving mechanism, a movable arm lifting mechanism, a fork bucket control mechanism and the like. Under the control of a computer, the multi-unit connection rod driving mechanism achieves driving of multiple low-power motors and high-power and high-torque power output, and meets the power requirement for high-load operation of the wood forklift. A hydraulic cylinder is applied to the configuration design of the wood forklift as a connection rod on the basis of the Pascal principle, through introduction of a hydraulic element, the problem that in the prior art, stress on two driving chains for lifting a movable arm is unbalanced is effectively solved, and the bearing stability is improved. The wood forklift not only has the characteristics of being high in transmission efficiency, high in response speed, high in motion precision, good in controllability, capable of saving energy, environmentally friendly and the like as a controllable mechanism, but also has better bearing performance and shock resistance through introduction of the multi-unit connection rod driving mechanism and the hydraulic element, can achieve the overload protection function easily and has great engineering application prospects and development potential.

The invention discloses a power control method for hoisting equipment. The method comprises the steps of: 1) detecting the current loading pressure of the hoisting equipment's power system, converting the current loading pressure into an electrical signal, and directly conveying the signal to ECU of an engine through a circuit; and 2) according to the electrical signal, outputting an engine speed matching with the current loading pressure. According to the method, the current loading pressure is transferred the engine ECU in the form of the electric signal, the mode and time for transferring an external load signal to the engine are changed, the time required for signal transmission is reduced, and the engine can rapidly response in advance. Thus, flameout caused by too much sudden fall of the engine speed can be avoided when the pressure load suddenly increases, thus effectively improving the power adaptability of engine under a low speed condition. The invention also discloses a power control system for hoisting equipment.
