Choosing Hoist Suppliers
Hoist Suppliers help lift and transport freight, building materials and engines. They are used in construction, warehouse operations and other industries. Rigging hoist equipment can be powered by manual or electric power. Some types require more maintenance than others.
Find the right hoist for your business by evaluating these characteristics:
Lifting Capacity
Hoists are used in a variety of settings to lift heavy loads that are too large for a worker to move by hand. They’re often seen on manufacturing lines, where they transport products between different stages along the assembly process. They also play a vital role in construction projects and warehouse operations.
A hoist’s lifting capacity is measured by the maximum gross load that it can safely lift under a specific working condition and operating configuration. It’s commonly known as the manufacturer’s rated capacity (MRC).
The MRC can vary depending on how the hoist is configured, its travel distance, and the weight of the load. It’s important to understand the hoist’s lifting capacity before making a purchase. The load capacity will hoist Suppliers determine whether a particular hoist is suitable for your application and will help you narrow down your options. You’ll also want to consider the type of suspension, trolley type, and other features. For example, you’ll need to choose between a fixed mounting or a trolley option and decide whether you need a rigid or swiveling hook.
Lifting Speed
Hoists come in various lifting speeds, which is important to consider as you choose equipment. The speed of a hoist affects its torque requirement, which is determined by the weight of the load and the gear ratio. Higher torque requirements require larger motors, which can add to the size and weight of the hoist and increase its power consumption.
Another thing to consider is how frequently you will be using the hoist. Hoists have a maximum duty cycle, which is the number of lift/lowering cycles they can complete in one hour. This is based on the total amount of time you make lifts and lowers each hour divided by the lifting speed of the hoist in feet per minute.
Hoist manufacturers design, produce, and install manual, electric, air, and hand chain hoists in capacities ranging from 1/4 to 2-ton. Some models are designed to operate on 115 or hoist Suppliers 230vac single-phase power while others can be wired for 208, 460, or 575v three-phase. These units are often used in garages, home workshops, and some light industrial facilities. Other types of hoists include free standing or wall mounted work station jib cranes and aluminum tie rod tool jibs.
Operation Type
A hoist is a device for lifting & lowering a load with the use of a drum or lift-wheel around which chain, rope or synthetic strap wraps. It can be operated manually, electrically or pneumatically. It can also be coupled to a structure, such as a crane, via a hook, clevis or lug. It can be used to move a variety of loads, including materials and equipment in manufacturing, transportation and warehousing applications.
The type of hoist you need depends on the load, travel distance and environment in which it will be used. For example, if the hoist will be used frequently and for long periods of time, an electric hoist may not be suitable as it can overheat and damage components. An air hoist, on the other hand, is better suited to these conditions as it is explosion-proof and has a 100% duty cycle.
A hoist supplier can offer an extensive range of options and accessories to suit your specific application. These can include load limiters, overload sensors and fault diagnostic systems. They can also provide servicing and repair services to help you maintain the performance and safety of your hoists.
Maintenance
Hoists must be serviced regularly to keep them in good working condition. A detailed inspection and lubrication are important parts of this maintenance process, which helps to prevent equipment problems. When performing maintenance, it is important to ensure that the power source is switched off and the isolating switch locked before starting work. A warning note should be attached to the switch to prevent the hoist from accidentally being operated while the inspection and repair work is underway. Only qualified service personnel should perform maintenance procedures on the hoist.
A daily visual inspection should be performed to check for damage and wear to the operating mechanism, load limits, hooks and latches, and lifting media (chain or rope). A more detailed inspection should be done on a monthly basis to document any existing problems with the equipment. Also, a service load test should be performed quarterly to observe how well the hoist functions while loading and unloading objects of various weights. Keeping spare parts on hand is a crucial part of hoist maintenance, as they can help to reduce downtime.
Safety
Hoists can be dangerous tools when they are used improperly. This is why it is important to follow the manufacturer’s instructions and keep the equipment properly maintained. This includes following the rated load capacities and recommended operating speeds, as well as keeping wire ropes and chains lubricated. Any twisted, kinked or damaged wire rope or chain should be tagged and removed from service.
In addition, the area where a hoist is located should be clearly demarcated using visible signs so that anyone not authorized to operate it knows not to enter the work area. Regular pest treatment should also be performed to prevent insects from weakening cables and attachments by chewing or gnawing through them.
Hoists should be designed with redundant critical circuits so that any accidental ground in the motor or DC power supply will not defeat field loss protection. This can be accomplished by placing a ground relay in the armature circuit of both the motor and the regulator drive and connecting its contacts to the emergency stop circuit. This will ensure that a hoist will always stop when power is lost.
