Industrial Air Brake Endorsement Types

airbrakes

An industrial (off-highway) air brake endorsement permits operating unlicensed vehicles equipped with air brakes used to transport natural resources on industrial roads. Code 18 covers unlicensed single-unit vehicles; Code 19 covers single-unit or combination vehicles. The endorsement appears in the 'restrictions' section of your licence.

Key Rules
  • Code 18 permits operating an unlicensed single-unit vehicle with air brakes on industrial roads
  • Code 19 permits operating an unlicensed single-unit OR combination vehicle with air brakes on industrial roads
  • You do NOT need an industrial endorsement to operate skidders, loaders, graders or yarders
📋

Driver's Duty to Inspect Vehicles

general

You must determine your vehicle is in safe operating condition before driving. Perform a pre-trip inspection daily before placing the vehicle in service and keep an up-to-date maintenance logbook. Report any defects to the proper company authority and never operate an unsafe vehicle.

Key Rules
  • Perform a pre-trip inspection daily before placing the vehicle in service
  • Keep an up-to-date maintenance logbook
  • Report defects to the proper company authority and do not operate an unsafe vehicle
🛑

Brake Testing on Industrial Roads

airbrakes

Industrial roads rarely have runaway lanes, so brakes must be in good condition. Test brakes before transporting any load and make a rolling brake test before descending steep hills. If brakes aren't safe, stop in a safe place, park and secure the vehicle, and don't drive until repaired.

Key Rules
  • Test the brakes before transporting any load
  • Make a rolling brake test before taking a loaded vehicle down steep hills
  • If brakes are not operating safely, stop, park securely and do not drive until repaired
📋

Right-of-Way on Industrial Roads

general

Use a turnout on a narrow road to give right-of-way to a loaded truck. Give right-of-way to a loaded truck coming down a steep hill. Drivers generally follow the rules of the road set out in the Motor Vehicle Act, with applicable sections determined by the Industrial Roads Act.

Key Rules
  • Use a turnout to give right-of-way to a loaded truck on a narrow road
  • Give right-of-way to a loaded truck coming down a steep hill
  • Follow the rules of the road in the Motor Vehicle Act as applied by the Industrial Roads Act
📋

Definition of an Industrial Road

general

An industrial road exists for transporting natural resources, machinery, materials or personnel, including company bridges, wharves and log dumps. It excludes public highways, forest service roads, development roads, privately owned farm/resident roads, power/telephone/pipeline maintenance roads, manufacturing plant roads and tote/cat/access roads.

Key Rules
  • An industrial road is used for transporting natural resources, machinery, materials or personnel
  • Public highways, forest service roads and development roads are NOT industrial roads
  • Company bridges, wharves and log dumps are included as industrial roads
🛑

Applying for Industrial Air Brake Endorsement

airbrakes

Apply at a driver licensing office. You must submit a medical report from a B.C.-licensed physician and a letter of proficiency from a current/previous employer outlining your experience, vehicle types and total operating time (minimum three months acceptable). An air brake pre-trip test is required.

Key Rules
  • A letter of proficiency requires a minimum of three months of experience
  • A medical report form completed by a B.C.-licensed physician is required
  • An air brake pre-trip test must be completed successfully before receiving the endorsement
🛑

Water Cooled Brakes

airbrakes

Many heavy industrial vehicles use water to prevent brake drum overheating. Turn on the water just after applying brakes when drums are only slightly warm, and turn off the water just before a complete stop so the drums contract evenly. Cooling only one side can crack the drums. Water tanks are pressurized with compressed air at least 15 p.s.i. (103 kPa).

Key Rules
  • Turn on water just after beginning to apply brakes when drums are only slightly warm
  • Turn off water just before a complete stop so brake drums contract evenly
  • Water tank pressure should be at least 15 p.s.i. (103 kPa)
🛑

Parking on Industrial Roads

airbrakes

When leaving a parked vehicle unattended, set the mechanical brake and secure the vehicle so it doesn't need air or fluid pressure to hold it in place. Overheating drums expand away from the shoes, reducing braking efficiency.

Key Rules
  • Set the mechanical brake when leaving a vehicle unattended
  • Secure the vehicle so it does not rely on air or fluid pressure to stay in place
📋

Warning Signals and Backing Procedures

general

Signal your intention to turn, stop or change course as on any public road. Before backing any truck or tractor-trailer into a loading area, sound your horn to warn others and have the head loader or responsible person direct you after confirming no one is in your path.

Key Rules
  • Sound your horn to provide a warning before backing into a loading area
  • Have a responsible person direct you into the loading area after checking your path is clear
  • Signal turns, stops and course changes as on any public road
📋

Railway Crossings on Industrial Roads

general

  • Once you have a learner's licence you must gain practical experience operating the type of vehicle you want to be licensed for, with instruction from an appropriately licensed driver or training facility

19.Shifting Skills

📋

Progressive Shifting and Shift Timing

general

Progressive shifting is recommended for many new vehicles with high-torque engines. The r.p.m. at which you shift becomes higher as you select higher gears. A tachometer helps determine when to shift. Smart driving techniques like progressive shifting save fuel.

Key Rules
  • Shift r.p.m. increases as you move into higher gears (e.g. 1,200 r.p.m. first-to-second, 1,350 r.p.m. fifth-to-sixth)
  • Use a tachometer to determine shift points
  • Refer to the vehicle manufacturer's guide for the best shifting method
📋

Shifting Gasoline (Non-Governed) Engines

general

For upshifting a gasoline-powered engine: start in low gear using only enough throttle to move; quickly shift to the next gear as the engine accelerates; allow the engine to develop more power before each shift as speed increases; engage the clutch smoothly while engaging throttle to avoid shock on drive train.

Key Rules
  • Start in low gear using only enough throttle to move the vehicle
  • Shift to higher gears as soon as you have the power
  • Engage the clutch smoothly and apply throttle simultaneously to avoid drive train shock
📋

Shifting Governed Engines

general

A governor controls fuel to the engine and regulates engine speed, allowing you to start on level ground and grades without using the throttle. Always squeeze the throttle rather than stab at it for smooth acceleration. If you need throttle to move off a loaded vehicle with a diesel engine, you should be in a lower gear.

Key Rules
  • Squeeze the throttle rather than stabbing/jabbing for smooth operation
  • Use only enough power to shift into the next gear
  • If throttle is needed to move a loaded diesel, use a lower gear
  • Engage the clutch smoothly to avoid shocking the drive train, load or passengers
📋

Entering Curves

general

Before entering a curve, slow to a safe speed and downshift to a gear that lets you use engine power throughout the curve. This keeps the vehicle stable and provides good acceleration when leaving the curve.

Key Rules
  • Slow to a safe speed before entering a curve
  • Downshift to a gear that provides engine power through the entire curve

20.Basic Driving Skills: Shifting Gears

📋

Progressive shifting and shift methods

general

Progressive shifting is recommended for many new vehicles with high-torque engines. The r.p.m. needed to shift increases as you select higher gears (e.g., first-to-second at 1,200 r.p.m., fifth-to-sixth at 1,350 r.p.m.). A tachometer indicates engine speed and helps you decide when to shift. An alternative is the standard r.p.m. split method. Always consult your manufacturer's guide for the best method.

Key Rules
  • Use progressive shifting for new high-torque engines, increasing r.p.m. at higher gears
  • A tachometer helps determine the correct time to shift
  • Consult vehicle manufacturer's guidebook for the best shifting method
📋

Shifting non-governed gasoline engines

general

For gasoline-powered engines without governors, start in low gear using only enough throttle to move. Quickly shift to the next gear as the engine accelerates, shifting to higher gears as soon as you have power. Let the engine develop more power before each higher shift. Engage the clutch smoothly and apply throttle at the same time to avoid drive train shock.

Key Rules
  • Start in low gear using only enough throttle to move the vehicle
  • Engage clutch smoothly and apply throttle simultaneously to avoid drive train shock
📋

Shifting governed engines

general

A governor controls the amount of fuel and regulates engine speed, letting you start on level ground and grades without using the throttle. Always squeeze the throttle rather than stabbing or jabbing at it for smooth acceleration. Use only enough power to shift into the next gear. You may skip gears on down or level grades depending on weight and gear ratios. If you must apply throttle to move a loaded diesel, you should be in a lower gear.

Key Rules
  • Squeeze the throttle smoothly rather than stabbing or jabbing at it
  • A governor lets you start on level ground and grades without throttle
  • If a loaded diesel needs throttle to move off, use a lower gear
📋

Entering curves

general

Before entering a curve, slow to a safe speed and downshift to a gear that lets you use engine power all through the curve. This keeps the vehicle stable and provides good acceleration as you leave the curve.

Key Rules
  • Slow to a safe speed and downshift before entering a curve
  • Choose a gear that provides engine power throughout the curve

21.Air Brakes: Foundation Brake Types

🛑

Wedge Brakes Operation and Adjustment

airbrakes

Wedge brakes use a wedge forced between brake shoes to apply the brakes. Unlike s-cam systems, drivers cannot easily check wedge brake adjustment. When lining thickness reaches a specific limit, automatic adjusters have failed. Only qualified mechanics should adjust or repair wedge brakes.

Key Rules
  • Drivers can't easily check wedge brake adjustment unlike s-cam systems
  • Wedge brakes should only be adjusted or repaired by a qualified mechanic
  • Automatic adjusters have failed when lining reaches inch limit for both linings
🛑

Air Disc Brakes

airbrakes

Air disc brakes use a rotor/disc mounted to the wheel hub that rotates with the wheel. Two brake pads press against either side of the rotor, similar to a large 'C' clamp. Most feature internal automatic adjustment for pad wear. Chamber stroke limits are the same as automatic slack adjusters. Drivers cannot easily check adjustment.

Key Rules
  • Air disc brakes press two pads against a rotor like a C-clamp
  • Chamber stroke limits are the same as for automatic slack adjusters
  • Air disc brakes should only be adjusted or repaired by a qualified mechanic
🛑

Air-Over-Hydraulic Brakes

airbrakes

Air-over-hydraulic brakes are found on middleweight trucks and buses, combining air brake and hydraulic braking features. The system consists of a compressor, governor, air storage tanks, foot valve and two air-over-hydraulic pressure intensifiers. Air pressure actuates the braking action while hydraulic pressure delivers braking force. Standard pressure is around 125 p.s.i. (862 kPa).

Key Rules
  • Air pressure actuates braking but hydraulic pressure delivers braking force to foundation brakes
  • Standard air pressure is around 125 p.s.i. (862 kPa)
  • An air brake-endorsed licence is required unless the system doesn't use an air treadle
  • Drivers must check air pressure gauges frequently as serious leaks stop brakes functioning
🛑

Air-Over-Hydraulic Parking Brakes

airbrakes

Many air-over-hydraulic systems have a parking brake chamber attached to the foundation brake. Applying the dashboard parking brake control valve applies the spring in the chamber, forcing a wedge between brake shoes. Releasing directs air pressure to contract the wedge and spring.

Key Rules
  • Parking brake controlled by same dashboard-mounted parking brake control valve as full air systems
  • Applying the parking brake forces a wedge between the brake shoes to apply brakes
  • Releasing directs air pressure to contract the wedge and spring

22.Introduction

📋

Purpose and Scope of the Guide

general

Operating commercial vehicles or vehicles equipped with air brakes requires special knowledge and skill because crashes involving large vehicles can be catastrophic. Most crashes are caused by driver error and are preventable. This guide provides information to apply for Class 1, 2, 3 or 4 commercial licences, or air brake, industrial air brake and heavy trailer endorsements.

Key Rules
  • Most commercial vehicle crashes are caused by driver error and are preventable
  • A professional attitude, plus knowledge and skill, is required to operate commercial vehicles safely
  • The guide is a source text, not a full training manual—practical experience and instruction are also required
