Isihluthulelo sokuthi kungani abashintshi bamathayi behlehlisa kalula izinhlobo ezahlukene zamathayi sisemandleni ahlinzekwa yi-hydraulic noma i-pneumatic systems. Ukuveza umehluko wamandla phakathi kwalezi zinhlelo ezimbili kukusiza ukuthi ukhethe isishintshi sesondo esilungile sesimo sakho esithile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle.
Amandla e-"Herculean" abashintshi bamathayi ancike ngokuphelele ezinhlelweni ezimbili ezinkulu zamandla: i-hydraulic ne-pneumatic, ehluke kakhulu futhi ifanele ukuhlukanisa izimo. Amasistimu we-hydraulic agcizelela "ukuzinza namandla," amandla adlulisa ngomfutho we-liquid ukuze alethe okukhiphayo okuphezulu nokungaguquguquki, ukuphatha kalula amathayi okunzima ukuwakhipha anjengamathayi awugqinsi nagijimayo. Zilungele izitolo ezinkulu zokulungisa izimoto kanye nokugcinwa kwezimoto ezithengiswayo, nakuba zinezakhiwo eziyinkimbinkimbi kanye nezikhathi zokuqalisa ezihamba kancane. Ngakolunye uhlangothi, amasistimu womoya, abeka phambili "isivinini nokushesha," eqhutshwa umoya ocindezelwe ukuze uqalise ngokushesha nokusebenza okulula. Zilungele izitolo ezincane zokulungisa kanye nokugcinwa kwezithuthuthu okubandakanya amathayi angasindi, ezihlinzeka ngezakhiwo ezilula kanye nezisekelo eziphansi. Umehluko oyinhloko usezindleleni zokukhipha amandla kanye nezimo zohlelo lokusebenza: amasistimu asebenza ngaphansi kwamanzi agxila "kumandla," kuyilapho amasistimu omoya egxila "ejubaneni." Ukuqonda lo mehluko kukuvumela ukuthi ukhethe isistimu yamandla ngezidingo zakho zokulungisa, uqinisekise kokubili ukonga komsebenzi nokusebenza kahle.
