Do you have a question about the Bil-Jax XLB-4016 and is the answer not in the manual?

Overview

The provided document is an Operation and Maintenance Manual for the BIL-JAX XLB-4016 Hydraulic Boom Lift, an aerial work platform designed for positioning personnel and their tools at overhead work locations.

Function Description

The XLB-4016 Hydraulic Boom Lift is a mobile aerial work platform. Its primary function is to elevate a work basket, allowing personnel to perform tasks at various heights. The lift utilizes two hydraulic cylinders for basket elevation, controlling both the lower and upper boom sections. A hydraulic powered motor and worm gear enable the boom to rotate 360° around a vertical axis. The hydraulic power unit consists of a reservoir, pump, and control valves. The lift is designed to be towed as a single-axle trailer, equipped with a two-inch ball hitch, surge brakes, breakaway safety cable, safety chains, brake lights, and side marker lights.

Important Technical Specifications

The XLB-4016 has a Rated Platform Load of 474 lbs (215 kg) total. It can achieve a Maximum Work Height of 40 ft (12.2 m) and an Extended Basket Height of 33.5 ft (10.2 m). The Maximum Outreach is 16 ft (4.9 m). The Elevation Rate, Nominal is 1 ft/sec (0.3 m/sec), and Boom Rotation is 360° Non-Continuous with a Rotation Speed of 318° per Minute, Nominal. The Basket Dimensions are 47 in. W x 31.5 in. D x 43 in. H (1.20 m x 0.80 m x 1.10 m).

The Power Source is 12 Volt DC, supplied by 2 x 175 Amp-hour Batteries. A Battery Charger (110/210 Volt, 25 Amp) is integrated for recharging. The Hydraulic Pressure is 3045 psi (21 000 kPa). The hydraulic system includes a Reservoir Capacity of 1.98 Gallons (7.5 Liters) and a total Hydraulic Capacity of 3.96 Gallons (15 Liters), using Energol HLP-HM22 (BP Oil) hydraulic oil.

The Gross Vehicle Weight is 2866 lbs (1300 kg), with a Tongue Weight of 160 lbs (72.5 kg). The Vehicle Weight is 2821 lbs (1280 kg). The trailer is equipped with Mechanical Surge brakes.

Usage Features

The XLB-4016 features two control panels: one for ground operation and another for operation from the basket. Both panels include motion enable pushbuttons and proportional hydraulic valves to control boom lift and rotation speed. Operation of elevation and rotation controls is interlocked, requiring the outriggers to be correctly extended and the trailer to be level. Only one boom motion is permitted at a time, and motions cease if a safe operating limit is reached.

Outrigger load sensing interlocks and safety switches prevent boom lifting operations until all four outriggers are properly extended, the trailer is level, and the full weight is loaded onto the outriggers. An interlock also prevents outrigger retraction if the boom is raised two inches or more.

Emergency lowering of the basket is possible via manual valve plungers on the boom lift cylinders. This can be done by two people (one actuating plungers, one operating levers) for smoother control, or by one person opening emergency ball valves and slowly pulling valve plungers. An emergency rotation feature allows manual boom rotation in case of power failure by turning a hydraulic rotation motor bypass valve.

The basket includes a 115 Volt AC outlet for power tools, rated for a 15-ampere load.

Maintenance Features

The manual outlines a comprehensive maintenance schedule, including Daily/Weekly Service Checks and Monthly Service Checks.

Daily/Weekly checks include verifying decal presence, proper operation of controls and indicators, ensuring booms remain elevated without drift, checking boom down limit switch and outrigger position switches, checking/adding hydraulic oil, checking tire inflation (55 psi / 3.8 bar when cold), checking trailer running lights, and inspecting battery electrolyte level.

Monthly checks involve cleaning battery terminals, checking charger operation, verifying manual lowering valves, checking wheel nut torque, lubricating the trailer tongue jack, lubricating the slew ring bearing, inspecting battery cables and wiring, replacing hydraulic oil and oil filter (annually or when contaminated), checking boom pivot pins and sleeve bearings for wear, inspecting and adjusting trailer brakes, and load testing boom lift operations with 450 lbs (204 kg).

The manual provides detailed procedures for:

  • Wheel Nut Torque Requirements: Specific tightening sequences and torque values (25 lb-ft, 50 lb-ft, 70 lb-ft).
  • Lubrication: Instructions for weekly lubrication of the trailer jack post and semi-annual lubrication of the slew ring bearing with NLGI Grade 2 multi-purpose grease.
  • Hydraulic System Maintenance: Daily inspection of hoses and fittings, fluid check and replacement (using Energol HLP-HD46 or specific SAE hydraulic oils), air bleeding procedures, and hydraulic cylinder removal/installation.
  • Hydraulic Pressure Checks and Adjustments: Procedures for checking and adjusting pump output pressure (main bypass valve) to 2538 psi (175 bar).
  • Limit Switch Checks and Adjustments: Instructions for adjusting the boom down limit switch and outrigger position switches to ensure proper interlock functionality.
  • Troubleshooting: A chart detailing common problems, causes, and corrections for hydraulic pump motor, outrigger extension, boom lift functions, boom slew function, and hydraulic system issues.
  • Material Safety Data Sheets: Information for lead acid batteries and AW-46 hydraulic oil.

The manual emphasizes the importance of using factory-approved parts, adhering to safety precautions, and consulting the manufacturer for complex repairs or adjustments.
