EHL-TS rated load between 250 and 3,000 kg

Mainfunction of EHL-TS Series

Spring Balancer is a device to suspend machines and equipment. Since the spring tension reduces the effective weight of the suspended load to nearly zero, you can control its vertical position effortlessly. Flexible operation is possible as stable balance can be achieved at any height

Features of EWF

Standard type with safety device (capacity: 4.5 Kg to 120 Kg)
The exposed part of the drum is reduced as much as possible to ensure worker safety.
The fall-arrest device prevents a suspended object from dropping even in the unlikely event that the spring breaks.
The balancer has a gauge for adjustment with respect to the suspended mass. Therefore, tension adjustment can be performed easily.

Accessories of EWF

Plain Trolley: When attached to a beam, this trolley enables smooth horizontal movement by hand.

General information of spring type cable reel

This reel utilizes the spring tension for winding. When the cable is pulled out, the spring is wound tightly and produces the counterforce that provides the power for winding up the cable. The models with the spring in a drum (Types CRF and CRL) are compact and easy to install.

Common types

Introduction of slip ring

ENDO’s slip ring is excellent on durability, quality and more. Slip ring assembly Slip rings are used to supply current to all kinds of rotating equipment. They are used for example on rotating cranes, manipulators, rotary tables, carousels, antenna installations, theatre stages as well as on all cable reel.

This cable reel is particularly suitable for long stroke lengths. Cable reel winds up and pulls out a cable using forward and backward rotations of its hydraulic motor. Compared with electric reels, its motor is compact and powerful. This product is resistant to the entry of dust or water and is suitable for large diameter cables (22 to 60 mm2) and long stroke winding. It is commonly utilized for tunnel excavators and concrete spraying carts. This type delivers higher performance for horizontal retrieve and is well suited for gantry cranes and carts with a long traveling distance. The drum, slip ring, and spring parts are separated to facilitate the maintenance and spring replacement.

Equipped with a motor, this reel serves as the primary driving force.
Additionally, it accommodates high-speed winding, continuous and frequent operations, and can handle cables with both large diameters and long lengths.
Furthermore, to ensure the best cable tension, the motor synchronizes perfectly with the movement of the object in motion.

Feature of contorq motor type cable reel

This “cable reel” boasts a driving force sourced from a totally enclosed fan-cooled motor combined with an oil immersion slip unit.
Moreover, it’s designed to ward off dust and rainwater.
Ideal for powering ship-to-shore cranes, stirring mechanisms, and steel mill carts, this reel offers a range of winding techniques.
However, one limitation is its inability to function in inverted or sideways installations.

Structure
Winding cable with Totally-enclosed-fan-cooled motor (IP55) drive. Assembled from the following modular components:
SLIP UNIT (slip mechanism)
Gearbox containing reduction gear Slip ring
Drum etc.
Slip unit
The SLIP UNIT plays a crucial role in ensuring consistent torque transmission from the motor.
This unit’s friction surface is created between radially arranged friction plates on the spindle and a circular plate linked to gears via an internal bearing.
By harnessing the friction from the oil film, it can regulate and deliver a steady torque. (For a detailed visual, refer to the accompanying picture on the next page.)

Control circuit (Reference)

This reel is equipped with a motor as the driving force.
This product supports high-speed winding, continuous operation, and frequent operation, as well as large diameter and long cables.
Motor-controlled synchronization with the motion of the moving object maintains the optimum cable tension.

Feature of Servo motor type cable reel

This reel uses a servo motor to wind up the cable. It’s a better choice for efficiency, energy saving, and cable longevity when compared to the inverter control type.
What’s special is that it has a unique feature called minimum tension control.
This feature works with the servo’s torque control to automatically manage the right winding force.
Moreover, this not only prevents cable damage but also slashes annual electricity usage by 97%, based on Endo testing. It’s perfect for large cranes that need to lift stuff vertically.
The servomotor, being a sophisticated power source, offers higher efficiency, energy savings, and longer cable life compared to the vector inverter system.
Here are some key points:
You can use it in challenging environments.
It uses Minimum Tensional Control for better torque control than the vector inverter system.
It generates a gentle winding force that extends the cable’s life more than the inverter system.
A combination of a Permanent Magnet motor and Minimum Tensional Control saves even more energy than the inverter system.
In Cable Replacement Mode, you can manually wind the reel forward and backward, ensuring easy and safe cable replacement.
The built-in control system in the reel body solves the headache of electrical work.
In short, this reel, with its servo motor, excels in winding cables

Applications
