A system of vertically mounted cylinders which enables each of the sheave wheel carriages to move up and down, thereby compensating for uneven wire rope lengths, thus balancing the loads and tension in the sets of wire ropes. This balancing process keeps the ore skips (or man cage) on an “even keel” as they travel up and down the shaft. The cylinder movements are monitored and controlled by an automated (PLC controlled) hydraulic power pack which provides hydraulic fluid to the single acting cylinders.
The hydraulic system consists of cylinder/s and a power pack which allows the fully loaded ore skip/s to be discharged into the headgear bin when skip/s docs in the discharge area inside the headgear structure. The cylinder movements are controlled by an automated (PLC controlled) hydraulic power pack which provides hydraulic fluid to the double acting cylinders.
A system of cylinder/s and a power pack which allows the ore inside the bin to be discharged onto conveyor belts or into trucks. The cylinder movements are controlled by an automated (or local operator controlled) hydraulic power pack which provides hydraulic fluid to the double acting cylinders.
This compact integrated system consisting of a double acting hydraulic cylinder and mini power pack which facilitate the movement of some mechanical devices. Typically, a radial door at the bottom of a silo which then allows ore to be discharged from silos by opening or closing a radial door. After the radial door is opened the ore flow rate, onto the conveyor belt, is controlled by purpose designed structures to prevent flooding of the conveyor belt. EHA’s can also be used to open and close ventilation control doors located in mining tunnels. These units are ideally suited for low frequency applications, where movement is required once or twice per hour.
The system entails the use of double acting cylinder/s and a power pack which allows the end user to open and close radial doors, typically found at the bottom of silos, surge bins or measuring flasks to facilitate the loading of conveyor belts, ore skips or rail cars. The cylinder movements are controlled by an automated (or local operator controlled) hydraulic power pack which provides hydraulic fluid to the double acting cylinders. Automatic closing of the radial doors, during emergencies or electrical supply failures, is also possible with these systems.
The systems can be used to drive the belt of chain conveyor system, rotary drives for sedimentation tank and other application where variable drive torque and speed is required. The use of variable or fixed displacement hydraulic motors and a power pack with variable displacement pumps allow the system almost infinite adaptability. These drives systems are often controlled by an automated (PLC) controlled hydraulic power pack which provides hydraulic fluid to the motors.
This system makes use of double acting cylinder/s and a mobile power pack which allows the end user to insert and remove spile bars in the chute when positive “isolation” of the ore flow is required. A small number of cylinders are mounted on moveable trolley bases so that the spile bars can be sequentially inserted or removed. The cylinder movements are controlled by a local operator using a hand operated valve located on the mobile hydraulic power pack. The mobile power pack and small number of cylinders make this a very economical system.
