Operation

Sheave Bearing Lubrication

The roller bearings in the Traveling Block sheaves require lithium based grease with extreme pressure qualities. Each bearing is lubricated through an individual passage drilled in the sheave pin. For convenience, both ends of these passages are accessible.

For each 24 hours of operation, inject 3 shots of grease in all of the fittings at either end, but not both ends, of the sheave pin. Use the lubrication corresponding to the operating temperature as indicated in Table 2.

Table 2: Lubrication Recommendations

Operating Temperature Recommended Lubricant

0°F to 155°F (-18°C to 68°C) NLGI Grade 2

-20°F to 40°F (-29°C to 4°C) NLGI Grade 0

Every 90 days, inject 3 shots of lithium based grease into the grease fittings at both ends of the becket and the grease fittings in all four side plate brackets.

Coat the contact surfaces of the becket and the hook or top drive bail with high tack extreme pressure grease.

Storage and Preservation

The packaging of the equipment should not be altered or removed before the equipment is to be commissioned. Disruption of the packaging may result in exposure of the equipment and its components which may cause damage and result in suboptimal operation.

In general, the equipment should not be submerged in water, exposed to excessive vibration, or allowed to collide with other equipment or property during transport or storage. This may cause severe damage to the equipment making it unsuitable for use at the site of commissioning.

A properly preserved Traveling Block will remain in operational condition for many years. The following are general recommendations for Traveling Block storage:

1. The traveling block should be stored indoors, although outside storage is allowable for brief periods.

2. The Traveling Block should be stored off the ground on wooden blocks when kept in outdoor or indoor locations.

3. Do not cover the Traveling Block with plastic because it will hold moisture against the metal parts.

4. Place the Traveling Block so the sheave and becket pins are horizontal and the weight of the traveling block is resting on the edges of the side plates and face of the becket.

Perform the following tasks when the Traveling Block is first put into storage and at regular 90-day intervals:

1. Lubricate each sheave bearing with three shots of grease while rotating at least one full revolution.

2. Inspect all painted surfaces. If corrosion is found, clean the area with emery cloth down to bright metal and coat with a zinc rich primer.

3. Lubricate each becket pin by putting three shots of grease into each of the three grease fittings for each pin (one in the end of the becket and one in each of the associated brackets).

4. Coat all unpainted surfaces with a suitable rust preventative. These surfaces include the sheaves, sheave pin, becket, and becket pins.
