The swivel boom with mast was designed for heavy duty live works on high voltage structures, particularly for removal of insulator strings in conjunction with the Insulator Cradle.

Swivel booms with mast RC400-0469 and RH1973/H-10 include two saddles (R070496), for pole mounting; one at the top and the other one at the bottom. These saddles have chain tighteners with adapters.

Swivel booms with mast RC400-0464, RC400-0465, and RH1973-814 were designed for tower mounting and use two hardware models: one saddle (RC400-0602) mounted at the bottom which is attached to the tower with two sets of screws and jaws for tower bracket and an included triple fork (FLV01644-1), installed at the top for attachment of the trolley poles.

When the mast is not required, the adapter (FLV18133-1) shall be used for attachment of the boom to the saddle (RC400-0602).

The attachment of the mast to the metallic structure is done with the use of three trolley poles (RH4721-112) and saddles for metallic structure (RM4742-3). These items must be specified separately.

Trolley poles heads are made from heat treated aluminum alloy and buttswivels are made from forged steel.

For all models, the connection of the boom to the mast is made through a strain link stick (RC400-0816) and a hoist (1500E), to be specified separately.

RC400-0464, RC400-0465, and RC400-0469 have a movable pole clamp on the square boom which can be adjusted in three different positions to facilitate the operation of the entire set at different angles of the insulator strings. The boom has an auxiliary head with two shackles on its end which it could be supported from, or for support of additional loads, tools etc.

SWIVEL BOOM WITH MAST

Composition of the Set:

- RC400-0464: (1) RC400-0602; (1) FLV01644-1

- RC400-0465: (1) RC400-0602; (1) FLV01644-1

- RC400-0469: (2) R070496

NOTE

The set composed of boom pole and mast pole has the working load increased only if it is assembled by a triple stick-set made by 03 Trolley poles, 01 Roller link stick and 01 hoist capable to withstand 2 tons (purchased separated).

The boom extension was designed for the lineman’s access to the line potential, using the bare-hand chair (FLV12563-1).

It is provided with two diam. 76 mm (3") cooper alloy clamps (FLV00196-5) for attachment to the head and square pole clamp of the boom. Also, one head with two eye links is available, being one for attachment of the chair and the other for guying purposes, using insulating pole and rope blocks.

 SWIVEL BOOM WITH MAST

Composition of the Set:

- RH1973-814: (1) RC400-0602; (1) FLV01644-1

- RH1973/H-10: (2) R070496

NOTE:

For loads greater than 272 daN (600 lb), the use of the saddle for metallic structure is recommended (RM4742), with a Ø 76 mm (3") cooper alloy pole clamp (FLV00196-5) plus an identical clamp for back-up, to avoid the slipping of the trolley pole, used in the tripod for support of the mast.
