What is ER Hoist
Our ER electric hoists are designed for peak performance-even on the toughest jobs in the toughest conditions. Quiet operation and minimal vibration lowers workplace noise pollution, helps reduce worker fatigue and extends the life of the hoist. The ER's smart brake has an electrical fail-safe design that uses DC current to control brake activation. The fast activation drastically reduces wear on the brake discs, preserving the correct brake gap. The result is a maintenance-free braking system with a 10-year hoist brake warranty. Rayvanbo's ER electric chain hoists are high quality, full-featured hoists that include the latest technologies that have earned recognition for their world class design. These models are absolutely the best electric chain hoists on the market today!

3 Key Benefits Of Electric Hoists
Ease Of Lifting
The purpose of a hoist is to be able to lift an item without the user having to physically absorb the load. Instead, the user simply has to ensure the load has been safely connected and then use the electrical controls to determine where the load is lifted to. Compare this to trying to manually lift an item, particularly something which is large, heavy or both and having an electric hoist take the strain offers no comparison. Ease of lifting has a wide array of benefits since it will mean tasks can be completed quickly and with a far reduced chance of an injury occurring. Also, fewer personnel will be needed to assist or supervise the lift, since the machine does the work on their behalf.
Increase Lifting Capacity
When the lifting capacity increases, so do the potential for the business's operations. The total capacity for electric hoists differs depending on the brand but is typically superior seen as they are designed for industrial environments. All of this means electric hoists not only lift incredibly heavy loads but offer unrivalled precision too, meaning the possibilities of your business become endless.
Hoists Are Cheaper Than Cranes
On average, electric hoists are cheaper than cranes. For any business that requires increased lifting capabilities, the cost can often be a barrier. But hoists offer another solution, without skimping on lifting capabilities. This means that hoists are more accessible, including to smaller businesses or startups. Without this option, the business could struggle to expand, and workers would be at increased risk of injury.

Products Details
When Should You Use An Electric Chain Hoist?
- Any time your capacity is 3 tons or less apply a chain hoist unless some other circumstance specifically dictates wire rope.
- Any time your application is in a critical area, and the portability of a spare chain hoist allows easy replacement of another unit in need of repair.
- Any time you need true vertical lift and the lowest cost.
- Any time initial cost and total operating cost are important.
Factors To Consider When Choosing Electric Chain Hoists
1. Load Capacity And Lifting Height
The first factor to consider is the weight of the loads you'll be lifting. Electric chain hoists come in different capacities, ranging from a few hundred pounds to several tons. Determine the maximum weight you need to lift and choose a hoist with a suitable capacity. Additionally, consider the lifting height required for your application. Make sure the hoist you select has an adequate chain length to accommodate your lifting needs.
2. Duty Cycle And Lifting Speed
The duty cycle refers to the amount of time the electric chain hoist can operate continuously without overheating. If you have high-volume lifting tasks or require continuous operation, opt for a hoist with a higher duty cycle rating. Lifting speed is another important consideration. Choose a hoist with a speed that matches your productivity requirements. Keep in mind that higher speeds may result in increased wear and tear on the hoist components.
3. Power Supply And Control Options
Electric chain hoists are available in different power supply configurations, such as single-phase or three-phase. Select a hoist that is compatible with your facility's power supply. Additionally, consider the control options that best suit your needs. Some hoists come with pendant controls for easy operation, while others may have remote control capabilities. Determine the level of control and accessibility required for your application.
4. Safety Features
Look for hoists equipped with essential safety features such as overload protection, emergency stop buttons, and automatic brakes. Overload protection prevents the hoist from lifting loads beyond its rated capacity, while emergency stop buttons allow operators to quickly halt the hoist in case of an emergency. Automatic brakes ensure the load remains securely held in place when the hoist is not in use.
5. Durability And Maintenance
Electric chain hoists are subjected to heavy use and challenging work environments. Choose a hoist constructed with durable materials and components to withstand the rigors of your application. Look for features such as corrosion-resistant finishes, sealed bearings, and robust gearboxes. Additionally, consider the ease of maintenance when selecting a hoist. Opt for models with accessible components and readily available spare parts to minimize downtime.
6. Brand Reputation And Warranty
Research different manufacturers and read customer reviews to gauge their reputation in the industry. Additionally, pay attention to the warranty offered by the manufacturer. A comprehensive warranty can provide peace of mind and protect your investment in case of any defects or issues.
Safety Precautions in Operating Electric Hoists
Pre-Work Inspection:
- Attached to every hoist is a checklist that must be completed prior to operation. Included in the checklist are features, aspects, and areas of the hoist that require inspection. Most checklists are dated in regard to the last time the hoist was activated and if there were any problems during operation.
- Check the hook and cable or chain for nicks, gouges, cracks, twist, saddle wear, load-bearing point wear, and throat opening deformity. The chain or wire rope should be sufficiently lubricated prior to operation.
- Wire rope should be inspected and examined for crushing, kinking, distortion, birdcaging, unstranding or strand displacement, broken or cut strands, and general corrosion.
- Short and brief tests of the controls should be completed for proper functionality as well as examinations of wiring and connectors.
While Operating The Hoist:
- Loads should be secured using a hook and sling or lifter. Care should be taken to ensure that the hoist is not overloaded.
- The hook and upper suspension should be in a straight line. The chain or body of the hoist should not come in contact with the load.
- The area around and under the load should be clear of all personnel. For extremely heavy or awkward loads, warnings may be necessary to inform people in close proximity to the load.
- All hoists have a published load capacity that must be strictly followed to ensure the safe performance of the hoist. Serious and dangerous outcomes can be the result of not adhering to hoist guidelines and weight limits.
