The SPYDERCRANE PC094 is a revolutionary Pick and Carry Crane (PCC) designed for safe and efficient lifting operations in various environments, particularly in tight spaces and busy settings like warehouses and mechanical spaces. This manual provides comprehensive operational and basic service information to ensure safe and proper use of the PC094.
Function Description
The PC094 is a hydraulically telescoping boom crane capable of self-propulsion. Its primary functions include:
- Travel: Moving the unit under its own power. The travel drive system is optimized for smooth, safe movement on hard, smooth, and level surfaces.
- Lifting and Maneuvering: Picking up and manipulating attached loads both vertically and horizontally.
- Pick and Carry: Traveling with an attached load, though with reduced travel speed and stability compared to unloaded travel.
The crane operates on a battery-electric power system, making it a zero-emission and low-noise solution ideal for enclosed structures with limited ventilation.

Usage Features
The PC094 features a comprehensive set of controls and indicators for both travel and crane operations.
Operator Aids:
- Anti-Two-Block (A2B) System: Prevents damage by stopping winch-up and boom-out functions if the hook block approaches the boom tip. It consists of an A2B Switch and an A2B Weight.
- Boom Length Sensor: Measures boom length for accurate working radius calculation and indexing the correct lifting profile.
- Capacity Limiting System (CLS): Combines boom length, lift cylinder pressure, and the A2B System to prevent overloading. It does not replace operator responsibility for safe loading.
- Lifting Profiles: Three discrete profiles (Heavy-Weight, Medium-Weight, Light-Weight) are indexed based on Boom Stage and Stabilizer status (STORED/EXTENDED) to determine rated load capacity.
- Percentage of Rated Capacity Indicator (PRCI): A three-color LED (Green: <80%, Yellow: <100%, Red: 100% or disabled functions) indicating the percentage of actual load versus rated capacity.
- Rated Load Chart: A decal on the carrier providing manual lift planning aid based on Boom Stage, working radius, and Stabilizer status.
- Stabilizers Stored Switch: A limit switch that opens when stabilizers are stored, affecting lifting and travel functions.
- Safety Override: A key-operated switch that bypasses safety systems and operator aids, used for storing the hook block or recovering from electronic safety failures.
- Travel Speed Indicator (TSI): A three-color LED (Green: 100%, Yellow: 50% or 25%, Red: disabled) indicating maximum available travel speed, linked to PRCI.
- Minimum Wire Rope Safety: Prevents complete un-spooling of wire rope, disabling WINCH DOWN when a minimum of 3-5 wraps remain.
Operating Modes:
- Travel Mode: For moving the PC094 without an attached load. Boom and hook block are stored, and stabilizers are stored. Allows maximum travel speed.
- PC Mode (Pick and Carry Mode): For lifting and traveling with an attached load. Boom and hook block are in working positions. Stabilizer position affects lift capacity and travel speed is automatically limited.
Controls:
- Tiller Handle: Used for steering and includes travel controls. Can be locked into Travel or Crane Mode.
- Accelerator: Spring-loaded thumb-operated control for forward/backward travel and speed. Releasing it stops the PC094.
- Auto-Forward Switch: A large "slam button" that, when pressed, stops the PC094 and travels it forward at a slow rate. Its function reverses if the Tiller is rotated more than 90 degrees.
- Safety Horn Button: Activates the safety horn.
- Keyed Ignition Switch: Starts and stops the PC094.
- Emergency Stop Switch: Immediately stops all functions when pressed.
- Boom Telescope Control Lever: Controls boom extension (BOOM OUT) and retraction (BOOM IN).
- Winch Control Lever: Controls hook block raising (WINCH UP) and lowering (WINCH DOWN).
- Boom Angle Control Lever: Controls boom angle (BOOM UP/BOOM DOWN).
Travel Angle Limits:
- Without Load: Max 10-degree incline.
- With Load: Max 5-degree incline.
- With Attached Load (side-side): Max 3-degree incline.
- Always travel straight-on when approaching inclined surfaces.
Maintenance Features
The PC094 requires regular preventative maintenance to ensure longevity and performance.
Daily/Shift Inspection:

Charging System:
- Uses a 120VAC supply.
- Requires a properly grounded 3-prong outlet with a fuse/circuit breaker rated for at least 15A.
- Extension cord requirements: 16AWG (max 25ft), 14AWG (max 50ft), 10AWG (max 100ft).
- Battery Charger Status Panel monitors charging status, including Ammeter (rate-of-charge), Bulk Charge Indicator (80% charged), Charge Complete Indicator (fully charged/maintenance mode), and Fault Indicator.
Important Safety Notes:
- NEVER operate or handle loads near electric lines.
- DO NOT perform maintenance when the PC094 is running or allow bystanders in the work area.
- DO NOT modify the battery array or charging components.
- DO NOT use if hydraulic oil leaks or electrical system problems are apparent.
- ALWAYS check wire rope condition.
- NEVER use to lift personnel or lift/move loads with personnel underneath the boom.
- NEVER side-pull loads.
- NEVER leave unattended with a suspended load.
- NEVER travel over unstable ground or exceed travel angle limits.
- NEVER use to tow or drag loads.
- NEVER tamper with hydraulic valves or safeties.
- NEVER modify or replace wheels with non-designed parts.
- DO NOT pressure wash the unit.
- Ensure the boom is properly stowed and hook is secured before hoisting or transporting.
- Use designated tie-down points for transport; DO NOT use lift points.
The SPYDERCRANE PC094 is a robust and sophisticated piece of equipment designed for specialized lifting tasks, emphasizing safety through its integrated systems and detailed operational guidelines.
