JLC Electric Chain Hoist The JLC is our favorite value oriented, USA made Electric Chain Hoist in up to two ton capacity. The unit has a compact and clean design. Oil bath gear train is long lived. Standard 5 pocket load sheave provides smooth lifting and long chain wear. Multiple disc brake, mechanical overload device and upper and lower limits are standard. The only drawback is that the JLC is built on only one frame size so the only 2 ton unit available is relatively sow at 8' per minute lifting speed. The pricing is also very competitive for USA build and CM quality. Crane 1 Services stocks this unit for immediate shipment. |

Key considerations in selecting the correct hoist are:
Capacity:
The load capacity of the hoist must exceed the weight of the heaviest load you plan to pick with the hoist's hook.
Power Supply:
Industrial electric chain hoists are widely available for 3 phase power while only smaller horsepower units (usually 3 ton and under) are available for single phase power supplies. Many single speed, 3 phase units are reconnectable for either 230V or 460V, 3 phase.
Lift Height:
The amount of chain supplied with the hoist will limit the available lift height; however the more chain supplied with the hoist, the heavier the unit will weigh and the larger the chain collection bucket or bag will be.
Suspension Point:
A key consideration in using an electric chain hoist is how and where the unit will be suspended. Chain hoists are offered with Lug, Hook and Trolley to suspensions. A lug mount must be fixed to a structure; hook mounts allow the hoists to be moved easily from one acceptable suspension point to another. Trolley suspensions allow the hoist to travel along a structural beam in order to transport the load and offer alternative pick points. Tolleys are offered in three different configurations: Plain (which is a manual push pull type unit); manual geared (which requires a hand chain to be overhauled over a chain wheel to move the trolley) and motorized (using a motor, controlled from the pendant station to drive the trolley motion.)
Hoist Speed (s):
Hoist speeds are a function of capacity, motor horsepower and reeving. The faster the hoist in a given capacity, the higher the required motor horsepower. Chain reeving can also change capacity in some hoist models. Hoists are available in single speed and two speed control using single or dual wound motors as will as variable speed options using state of the art variable frequency drives. Variable frequency drives have come done in price to the point that they are only a little more expensive than two speed motor applications today.
Hoist Braking Means:
Electric hoists are all furnished with a motor brake that stops the motion of the motor when the up or down button are not depressed. In addition, some manufacturers include the added safety feature of a weston style mechanical load brake that further controls lowering speed and stops the load in the event of a motor brake or motor shaft failure.
Control:
Most hoists are controlled from a cable suspended pendant station with a button supplied for each motion or direction. A hoist with a motorized trolley would generally be supplied with a 4 button pendant with buttons controlling up/down, forward/reverse. To increase safety, an emergencey on/off switch which shuts off mainline power to the hoist motors can be easily added.
Available Headroom:
The available headroom is the distance you have from the top hoist suspension point to the position of the load hook in the required upper (highest lift) position. The hoist headroom of the hoist you select must not exceed your available headroom or you will not be able to lift your load to the desired height. The load heights, pick points, lifting devices (slings) and the placement points must be taken into consideration when you determine available headroom. In general, the higher the capacity of the hoist,the more headroom will be required. Note that some brands have slightly better headrooms than others at certain capacities and chain reeving configurations. Ultra low-headroom units are availble at a higher cost that place the hoist reeving in front of the hoist rather than below the hoist to maximize lift height.
Duty Requirement:
Duty requirements are a major consideration in the selection of electric chain hoists. Most manufacturers offer lighter duty units at a savings from their heavy duty offerings. If you buy a light duty hoist for a heavy application, you will experience significant breakdown issues as well as short hoist life.
Environment:
The environment of the hoist also plays a large role in the proper selection of the hoist. Most hoists are designed for inside applications in a dry, relatively dust-free environment. Moisture, corrosive elements, dust or abbrasive particulates may require the use of special, chain, controls and other features to maximize the troublefree life of the hoist.
