SWIVEL BOOM WITH MAST

The boom pole with mast is intended for heavy duty high voltage structures, particularly for removing insulator chains with the aid of the cradle.

In the boom poles with mast (RC400-0469 and RH1973/H-10) two saddles (R070496) already included are used to attach the gin to the pole: one at the top and one at the bottom. These saddles have handwheel chain stretchers.
In the boom poles with mast (RC400-0464, RC400-0465 and RH1973-814),
designed for tower mounting, two hardware models are used: a saddle (RC400-0602) mounted on the underside, which is attached to the tower, with two sets of screws and angle jaws, and a triple fork (FLV01644-1), already included, installed on the upper side, for coupling the trolley poles.

When the mast is not necessary, the adapter (FLV18133-1) must be used to couple the boom to the saddle (RC400-0602).
The coupling and the formation of the mast stabilization tripod on the metal frame are made by three trolley poles (RH4721-112) and respective metal frame saddles (RM4742-3), both specified separately.

The trolley pole have heat-treated aluminum alloy heads and forged steel swivel eye.
On all models, the mast is held in the mast with a strain link stick
(RC400-0816) and a hoist (1500E), both specified separately.

The mobile pole clamp on the square boom (RC400-0464, RC400-0465 and RC400-0469) can be adjusted to three different positions for easy operation of the assembly at different angles of the insulator chain. The boom has at its end an auxiliary head with two shackles for retaining or holding additional loads, tools, etc

NOTE
The swivel boom with mast has the rated working capacity above only when mounted with the arm support tripod, consisting of 3 trolley poles, 1 strain link stick, and 1 2-ton hoist (purchased separately).

The square swivel boom extension is used to bring the electrician to potential through the potential access chair (FLV12563-1).
It has two Ø 76 mm bronze alloy pole clamp (FLV00196-5) for coupling to the square head and the square pole clamp of the boom pole. It also has a head with two eyes, one for installation of the potential access chair and other for bracing with an insulating pole and block.

NOTE
For loads greater than 272 daN (600 lb) we suggest using the metal frame saddle (RM4742) with a 76 mm bronze alloy pole clamp (FLV00196-5) and an identical rear pole clamp to prevent slippage of the trolley pole used on the mast support tripod.
