Strain Link Stick
Strain Link Stick

On deadend structures and running corners, a Strain Link Stick is used as insulation between rope blocks and a cum­a-long clamp.
Conductor loads on long spans and H-frame structures are sometimes greater than can effectively be handled with wire tongs. To supplement the wire tongs, a Strain Link Stick is attached to the conductor close to the wire tong. The Strain Link Stick is supported from above by rope blocks, which are operated in unison with the rope blocks attached to the wire tong.
Strain Link Sticks are also used to support the middle conductor on H-frame structures during insulator or crossarm changes.
Hooks and ferrules are made of heat-treated aluminum alloy for the best ratio of high strength to light weight. Butt rings - for attaching rope blocks or hand lines - are forged of high quality steel. Butt swivel spins freely on ball thrust bearing. The edges of the jaws of Chance Link Sticks are rounded to prevent scarring of conductors.

Roller Link Stick
Roller Link Stick

The Chance Roller Link Stick is used to spread and hold conductors aside at midspan when relocating poles. It is applied to the conductor at the pole and pulled to position by a hand line attached to the butt ring. The handline should be secured by a temporarily installed screw anchor or other fixed object.
The tool is also used for measuring conductor-to-ground clearance by attaching a measuring tape or length of rope to the butt ring. Poles for Roller Link Sticks are 1-3/4 inches
... rotating the pole closes the hook ... leaving the head free to roll along the conductor.

Applications and design
Key to many transmission and EHV maintenance jobs, these hot-line tools help support conductors while insulators are removed and replaced. Adjustable strain poles can be used with yoke plates and hook assemblies at the conduc­tor and structure ends of suspension, V-string or deadend insulator strings.
To support the hot-end trunnions or hooks, five stainless ­steel crosspins are located at 6" intervals on the 2"-diameter Epoxiglas® poles. To engage deadend and suspension yokes at the hot end also requires the adjustable pole clamp of heat-treated aluminum. This pole clamp can be unlocked and positioned by hotsticks.
On the cold end, a high -strength steel strain-jack with bronze tongue provides take-up with a ratchet wrench and trunnions. Wrench and trunnions must be ordered as separate items. Standard strain jack furnished with each strain pole provides 12" of adjustment. Longer strainjacks (for 24" or 36" of take-up) and extra pole clamps also may be ordered as options below.

Insulator Cradles
Transmission Insulator Cradles

Three basic types of Insulator Cradles are available for various insulator changeout requirements:
TRANSMISSION CRADLE is designed to be used on 69 kV to 115 kV deadend or suspension strings supported by a pair of wire tongs or link sticks.
EHV TROUGH-DESIGN CRADLE is designed to be used on 345 kV to 500 kV deadend or suspension strings and in combination with insulator cradle carriers for moving the insulators. (See below.)
EHV SIDE-OPENING CRADLE is designed to be used on only EHV deadend strings for removing only one string in a double, triple or quad deadend bundle. (See below.)

TRANSMISSION INSULATOR CRADLE
This Chance Insulator Cradle is used to make insulator changes by supporting the string while damaged insulators are replaced, or to pivot the string so that it may be removed and lowered to the ground. On deadends or running corners these cradles are used in conjunction with strain carriers; and in straight suspensions they are used with various types oflink sticks or adjustable strain pole assemblies.
Insulator Cradles are made with three 1-1/2” dia. Epoxiglas® poles. Light in weight, they are easy to handle and adaptable to many applications.
Lugs located at the forward end of the cradle are used to support the insulator string with a pair of wire tongs or link sticks. The back end of the cradle is supported by ropes tied at the structure. Hinged in this manner the insulators may be lowered or raised to the best position for changing damaged insulators.
In some cases, the cradle is supported in eyes located on the forward yoke of Two-Pole Strain Carriers. This is done when raising or lowering of the insulator string is unnecessary.

EHV Trough Design Insulator Cradle

This Chance Cradle is used for making insulator changes on lines energized up to and including 500 kV. It is used to lower insulator strings on deadend and swinging-corner construction, and to raise the insulators on long suspension units. Heat-treated aluminum castings, durable Epoxiglas® poles, and steel hardware combine to make the cradle a strong and dependable piece of equipment. The aluminum castings are a weight-saving feature providing ease in handling. The deep "trough" design of the cradle holds the insulator string securely and prevents accidental dropping of the string while the slotted insulator-retaining plate secures the top insulator of the string. The insulator-laden cradle can be raised or lowered for easier insulator changes using a bail attached to a link stick. Hooks are furnished for installing and removing the deadend tool from insulator yokes.
The Insulator Cradle Carrier utilizes a spiral link stick as a support member for the three hook and clamp assemblies and has a 2-1/2” Epoxiglas® insulated ridgepole. The maximum load is 500 pounds.

Structure Yokes
TOWER YOKE
The Tower Yoke fits over the tower arm, serving as a support for the Chance Strain Poles to relieve tension on the suspension insulator string through the "hot end" yoke and the conductor yoke plate.
The legs of the yoke are so designed that they can be adjusted to fit most tower structure configurations. Still, it is recommended that the design drawings of the tower arms be submitted to Hubbell Power Systems, Inc. with the Tower Yoke order for engineering evaluation to assure a proper fit. Swivel trunnions are 26" center to center.

STEEL ARM YOKE
Designed for use on the arm of a steel pole, the Steel Arm Yoke mounts over a 3/4-inch-thick end plate as shown at lefL. Swivel castings in the end of the yoke assure proper alignment of the Chance Strain Poles to the conductor-end yoke. The load rating is dependent upon the angle of the end plate on the arm; 45° is maximum angle allowed with a maximum load of 9,000 pounds. In-line loading of the yoke permits a maximum load of 15,000 pounds. Bronze pins place the strain poles 21 inches apart, center-to-center. A lifting eye is cast into the top of the yoke for the purpose of landing the yoke upon the end plate of the pole arm.

Trolly Pole Suspension Insulator Tool
Trolley Pole Suspension Insulator Tool

The Trolley Pole Assembly serves as a convenient method of rolling a string of suspension insulators into the structure so that the damaged units can be replaced. The tool can be fastened, horizontally under the tower arm, using tower type wire tong saddles.
Two types of Trolley Wheel Units are available with single (H47234) or tandem (C4000152) wheels. The tandem wheel units are used on extremely long strings of insulators for better weight distribution. Both trolley wheel types will roll on either a 2'/2" or 3" Epoxiglas® pole.
The slotted Suspension Insulator Attachment bolts to the end ofthe Trolley Pole and can be fitted under the top insulator. So applied, the entire string can be lifted free by a slight down pressure on the structure end of the Trolley Pole.
The insulators are returned to position on the Trolley Pole after the necessary changeouts have been made.
