Std. pendant hangs approximately 4 ft. above the hoist's fully extended bottom hook. For lifts or push button cord lengths other than
standard, use 10 ft. base price plus adders for load chain and push button cord.
Hoists may require a chain container based on the capacity, lift or suspension, consult us.
Lifts larger than stated "Max. Lift w/Canvas Chain Cont." may require steel chain container for balance, consult us.
Standard power supply cord 1/8 - 5 Ton is 15 ft. For optional 30 ft. length add $145.75
. Standard power supply above 5 Ton is 30 ft
Extra per ft. over 30 ft. is $9.73
. No price deduction for shorter lengths.
Cable support hangers included for every 5 ft. of power supply cord. Thermal motor protection is standard.

NER Dual Speed Electric Chain Hoists
Smart Limit Option
|
Our unique Smart Limit is available on NER three phase dual speed electric chain hoists. Unlike geared limit
switches, this Smart Limit allows the user to add upper and lower limit positions that can be conveniently
programmed at the pendant. The soft stop feature within the Smart Limit slows the hook down as it approaches
each limit for smooth and very precise load positioning. |

*The NER/ER030LD listed is the previous hoist model (2 speed hoist & trolley via contactor control; trolley via VFD.
Consult us for VFD packages). |
Specify hoist model and voltage. VFD Control is not reconnectable voltage.
Retrofit Smart Limit to existing NER Series hoist is not available.
Smart Limit can only be added to NER dual speed (VFD Control) units.
Infinitely Variable Speed - VFD Adder (Add to Dual Speed Prices)
• 2-Step infinitely variable - add $138.66
for each infinitely variable directional axis.
• 3-Step infinitely variable - add $485.21
for each infinitely variable directional axis. |
|
| (N)ER VFD HOIST CONTROL DESCRIPTIONS |
|
Dual Speed Control
Uses a 2-step button and a VFD to control the speed. Pressing the button to the first step causes the hoist to
accelerate smoothly to the low speed. Pressing the button to the second step causes the hoist to accelerate
smoothly to the high speed. Releasing the button from the second step to the first step causes the hoist to
smoothly decelerate to the low speed. Releasing the button completely from any step causes the hoist to
decelerate quickly to a stop with the brake holding the load. |
|
2–Step Infinitely Variable Control
Uses a 2-step button and a VFD to control the speed. The acceleration rate can be changed by changing
parameters in the VFD. The 2-Step Infinitely Variable differs from Dual Speed Control in that when releasing
the button from the second step to the first step it will maintain whatever the speed was at the instant before
the button arrived at the first step. This allows you to hold any speed between the low and the high speed.
If the hoist is operating at a speed that is less than high speed, and you wish it to operate at a faster speed,
press the button to the second step to accelerate the hoist. When you reach the desired speed, release the
button to the first step. Note that there is no deceleration function other than completely releasing the button. |
|
3–Step Infinitely Variable Control
Uses a 3-step button and a VFD to control the speed. This control is similar to the 2-Step Infinitely Variable
Control with the added feature of a deceleration function. If the hoist is operating at a particular speed and
you wish it to operate at a faster speed, press the button to the third step to accelerate. When you reach the
desired speed, release the button to the second step to maintain that speed. If the hoist is operating at a particular
speed and you want it to operate at a slower speed, release the button to the first step to decelerate. When you
reach the desired speed, press the button to the second step to maintain that speed. |
