Hoists have many hidden parts, including the drive motor, hooks, and lever locks. Critical parts include the safety catch, operating handle, and mounting bolts. Air-operated hoists require line filters to prevent damage. Hoists are used to move heavy objects in manufacturing facilities, and critical parts include the control panel and drive motor. Water strainers and oil injection units aid in lubrication and prevent accidents. Emergency stops and spool clutches prevent accidents, and flashing lights and buzzers alert workers to safety issues.
There are many hidden parts of the hoist, such as the drive motor, hoist hooks and lift arm lever locks, that can often be overlooked with a quick glance. Other very important parts of the hoist such as the safety catch, operating handle and mounting bolts are critical to the operation and use of the hoist. Cables, chains and slings accompany roller guides and control switches are important parts of any hoist. Air-operated hoists use an air compressor, air hose, and line filters to prevent damage to the internal workings of the engine from exposure to water from the air lines.
In a manufacturing facility, a hoist is often used to move heavy objects from one workstation to another, as well as to load finished materials onto trucks. Many of the parts of the hoist used to move materials are often overlooked, with only the hook and chain or cable easily seen. Some of the invisible hoist parts used to build a working hoist are the cable/chain reel, the cable/chain roller guide, and the drive gears that actually engage the reel and release or retract the cable/chain. Several critical parts of the hoist which control the lifting function of the hoist are the control panel which houses all the control switches of the hoist, the drive motor which can vary from an electric motor to an air motor.
With an electric hoist, several components and parts of the hoist are located in the building’s electrical system. Fuses and wiring essential to supply power to the engine are commonly run within walls where they remain out of sight. An air hoist requires special lifting parts in the form of air line and filtration components placed between the hoist and the air compressor to be installed.
Water strainers that remove most of the trapped water from the air lines are critical to the long life and smooth operation of your hoist. One proactive component typically found installed in the air line of a lift engine is an oil injection unit. This device injects a fine mist of oil into the air line at set intervals to aid in lubrication of the lift motor.
Other proactive components of a hoist are emergency cable/chain stops that prevent a load from accidentally falling from a raised position. Also often incorporated into the hoist design is a spool clutch designed to slip when a load exceeds the hoist’s lifting capacity. Flashing lights and buzzers are parts of the hoist that are sometimes installed on the hoist to alert workers when the hoist is traveling overhead so they can be aware of any safety issues related to the movement of the hoist.
