Product Description
Mining Use Xihu (West Lake) Dis. Rope Pulley Head Sheave
Xihu (West Lake) Dis. wheel device can transport the whole under the premise of swimming round and fixed wheel adopts integral cast joint structure, wheel hub, wheel rim for cast steel materials, spoke for the channel steel, after welding the whole annealing process again.
Considering the replacement bearing maintenance convenient, leave replace bearing remove space, guide wheel device structure adopted eccentric layout.
Xihu (West Lake) Dis. shaft using middle carbon alloy steel forging whole, adopting the structure of the cast joint pulley, equipped with PVC or nylon liner, protect the wire rope.
Imported or domestic spherical roller bearings, also can install bearing temperature measuring element.
In order to prolong the service life of wire rope, rim inside wedge liner with wear-resisting, withstand voltage, using D660 (1571) or nylon liner.
1) eccentric layout: on 1 side of a winding wheel have replaced bearing dismantling space, can not remove the pulley mechanism, only for bearing maintenance and replacement.
2) symmetry layout: relative with 4 wheels on both sides of the 2 bearing seat is symmetrical, but need to replace the bearing shell, only to remove the pulley mechanism.
sheave pulley and the common malfunction and technical guide wheel
1) to the problem of old structure pulley sliding bearing to burn tile should improve lubrication way; Because of the pulley is installed on the derrick, daily maintenance inconvenience, should add temperature alarm device, so as to timely maintenance to prevent the tile burning failure, or the original sliding bearing replacement into rolling bearing structure
2) for old structure pulley rope groove without liner, can no longer add padding on the original rope groove, need to change a gasketed pulley, adjacent assembly size can remain motionless, and installation
3) for mountain transportation difficulties or have some difficulties in roadway transportation in underground mine, the pulley is (guide wheel) change the structure into 2 or 4 and a half of head sheave.

Are there variations in rope pulley sizes and configurations?
Yes, there are variations in rope pulley sizes and configurations to cater to different applications and load requirements. Here’s a detailed explanation:
1. Sizes: Rope pulleys come in a range of sizes to accommodate various rope diameters and load capacities. Smaller pulleys are typically used for lighter loads or in situations where space is limited. Larger pulleys are employed for heavier loads and applications where additional mechanical advantage is required. The size of the pulley is determined based on factors such as the diameter and type of rope used, the anticipated load, and the available space for installation.
2. Configurations: Rope pulleys can be configured in different ways to suit specific requirements. Some common configurations include:
- Single Pulley: A single pulley consists of a single wheel with a grooved rim and a stationary or movable axle. It is used for basic redirection of force and change in direction.
- Double Pulley: A double pulley, also known as a block and tackle, consists of two pulleys mounted on a common axle. It provides increased mechanical advantage by dividing the load between the two ropes. Double pulleys are commonly used in lifting heavy loads.
- Multiple Pulleys: Pulley systems can be created by combining multiple pulleys. These systems can include fixed and movable pulleys arranged in various configurations, such as the compound pulley system or the complex block and tackle system. Multiple pulley configurations offer higher mechanical advantage and are used for lifting extremely heavy loads with reduced effort.
The choice of pulley size and configuration depends on factors such as the weight and type of load, the required mechanical advantage, the available space, and the specific application. Engineers, riggers, and designers consider these factors to select the most appropriate pulley size and configuration to ensure safe and efficient lifting and movement of loads.
