What This Manual Covers

The Sandvik SB120S Boom Operation and Maintenance Manual is far more than a basic operator’s guide. It is a complete service library for the SB120S boom, combining operational theory, maintenance schedules, repair procedures, and troubleshooting in a single PDF. Every hydraulic function of the boom is explained with detailed oil-flow descriptions – from boom lift and lower to swing, zoom, bolting head tilt and swing, and rotation mechanism roll-over movement. The manual details the proportional boom control valve, pressure-controlled non-return valves, overcenter valves, and the swing extreme position monitoring circuit with its plunger valves and shuttle valves.

For maintenance, the manual provides greasing point diagrams with multiple views of the boom, torque specifications for cylinder pins and mounting bolts, clearance checks for the boom’s inner and outer tubes, and slide plate inspection criteria. The repair instructions walk through disconnecting the rotation mechanism, adjusting tube clearances, replacing bearing bushings and slide plates, flushing and bleeding the hydraulic circuit, and testing the plunger valve. Detailed disassembly procedures cover the rear assembly, boom swing head, and rotation head 230, with exploded-view illustrations for each step.

The troubleshooting chapter addresses the most common hydraulic problems: slow or non-functioning functions, the boom not holding its position, and the boom failing to swing sideways. Each symptom is linked to probable causes and corrective actions, from checking oil level and viscosity to inspecting overcenter valves, plunger valves, and one-way restrictor valve adjustments. The manual also covers the pressure-relief valves that protect the bolting head forward tilt and swing cylinders from excessive pressure during working or return movement.

The Russian-language supplement sections extend the manual’s coverage to the rotary actuator (Роторный привод) and hydraulic cylinders (Гидравлические цилиндры), including their operating principles, seal replacement procedures, assembly torque values, and expansion pin installation. The rotary actuator section explains how axial piston movement translates into rotary movement through left-hand and right-hand helical gears, while the hydraulic cylinder section covers load holding valves, cylinder disassembly, piston seal installation, and line testing procedures.

Who This Manual Is For

This Sandvik SB120S Boom Operation and Maintenance Manual is written for equipment operators, maintenance technicians, and field service engineers who work with the SB120S hydraulic drilling boom. If you operate or maintain a Sandvik rig fitted with the SB120S boom for tunneling or bolting work, this manual gives you the correct procedures, torque values, clearances, and hydraulic schematics to keep the boom running safely and efficiently. It is also a valuable reference for workshop managers planning repairs or training staff on the SB120S boom’s hydraulic systems.

Because the manual includes both English and Russian sections, it serves bilingual teams working in regions where Russian-language documentation is required or preferred. The Russian cylinder section is particularly useful for rebuild workshops that service hydraulic cylinders from Sandvik rigs, as it covers piston and rod seal replacement, bushing installation with temperature differentials, and expansion pin torque values.
