Drive: The winch is driven by two axial piston type hydraulic motors through a two stage, spur gear reduction. The first stage of the reduction runs in a totally enclosed, oil tight gear case. The motors are connected in a series parallel circuit to give two speed and pull ranges as specified above.
Oil Required:
45 US gpm at 1,500 psi
34 US gpm at 2,000 psi
27 US gpm at 2,500 psi
23 US gpm at 3,000 psi
Frame & drum: Fabricated steel. All mild steel parts are sand blasted and coated with an epoxy primer. The complete winch is finished with one coat marine grade epoxy.
Gears: All gears are steel with machine cut teeth and are manufactured to AGMA Class 6 standards for industrial gears.
Bearings: The drum and drive shafts are supported on totally enclosed ball type bearings that are held in cast iron housings. All other shafts are supported on heavy wall bronze bearings that are held in fabricated steel housings. Provision is made for the lubrication of all bearings.
Base: The winch is equipped with a rotating base. This consists of a set of clamps that are located at the bottom of the winch frame. When these are released, the winch may be manually rotated through 360 and re-clamped in any desired position.
Clutch: The drum is connected to the drive by a manually operated jaw type clutch. When the clutch is disengaged and the brake is released, the drum will free wheel.
Controls: The winch is controlled by a single lever, three position valve that will give forward and reverse operation and is spring returned to a central neutral position. A second, single lever, two position detent valve is provided to select either the low or the high operating range of the winch. Also included is a hydraulic brake valve. This will automatically hold the load when the main control valve is in the neutral position and will give controlled payout of the line under load. All controls are supplied mounted and pre-piped at the rear of the winch.
Spooling: The winch is equipped with a fully automatic spooling mechanism. This consists of a set of vertical, stainless steel rollers that are mounted in a fabricated steel roller carriage. The rollers are supported on sealed ball bearings and stainless steel shafts. The space between the rollers is adjustable to accommodate wire diameters between 7/32" and 1". The roller carriage is also equipped with a horizontal stainless steel roller. This will support the wire when it is in the slack condition. The roller carriage may be tilted to accommodate wire leads from zero to 30 degrees above the horizontal.
The roller carriage assembly is mounted in a fabricated steel spooling carriage. This is supported on two stainless steel guide bars and is driven directly from the drum by a stainless steel roller chain reduction, a stainless steel diamond screw and a hardened steel shuttle. A clutch hand wheel is located at one end of the diamond screw. When this is disengaged the carriage maybe moved manually to suit the position of the wire on the drum.
A variable speed reducer is located in the drive between the drum and the diamond screw. This may be manually adjusted so the winch will spool any size of wire between 7/32" and 1" diameter.
Brake: The winch drum is equipped with a stainless steel, self-energizing, band type brake that is fitted with a woven lining. This is applied and released by a hand lever that is equipped with a ratchet holding device.
Slip rings: Provision can be made in the drum and at one end of the drum shaft for the mounting of a slip ring assembly of the customer's supply.
Wire counter: Provision is made on the winch for the mounting of an electronic wire counter. This consists of a sheave with a pitch circumference of one meter that is mounted on the spooling carriage. A suitable shaft and mounting arrangements are provided for the attachment of the counter-sensing unit.
Weight: Approximately
4,900 lbs, not including the wire
