The Lima Type 34 is a classic heavy-duty crane model renowned for its robust construction and reliable performance in lifting and material handling tasks. Proper knowledge and availability of parts for this crane are critical for maintaining operational efficiency and safety.
Key Components and Parts
Operators value the Lima Type 34 for its rugged design and adaptability to various jobsites, ranging from construction to heavy industrial lifts. Proper parts availability and maintenance practices are key to minimizing downtime during heavy operation cycles.
Summary
Lima Type 34 cranes are built with durable steel components including booms, outriggers, and swing mechanisms supported by powerful hydraulic and electrical systems. Ensuring access to genuine replacement parts and adhering to routine inspections and service enable continued safe, efficient crane operations. Familiarity with key components and system functions helps operators and technicians sustain performance and safety standards on demanding projects.
Key Components and Parts
- Boom and Boom Extensions: Made from high-strength tubular steel, with lengths generally customized to job demands. Extensions provide increased reach for various lifting scenarios.
- Hoist Drums and Wire Ropes: Include main and auxiliary hoist drums with grooved or smooth lagging designs for optimal rope grip. High-quality wire ropes rated for capacity and durability are essential for safe lifting.
- Outriggers and Support Beams: Heavy-duty steel assemblies designed to stabilize the crane during lifts. Outriggers are often hydraulically extended and feature locking mechanisms.
- Swing Mechanism: Large diameter single-row anti-friction bearings with sealed races prevent rocking motion during rotation. Swing gears and motors are built for long life and smooth operation.
- Hydraulic Systems: Dual hydraulic pumps with flow rates around 70 GPM power hoist, swing, and outriggers. Hydraulic controls are often “electronic over air” or traditional valve operated, depending on model and retrofits.
- Counterweights: Steel blocks designed to balance boom loads, customizable depending on boom length and jib attachments.
- Operator Cab: One-person, all-steel construction providing visibility, ventilation, and safety with features like air conditioning and instrument clusters displaying engine and operational parameters.
- Electrical and Safety Systems: Include load moment indicators for lift management, multiple CCTV cameras for visibility, and safety alarms or limit switches.
- Regular inspection of moving parts, especially wire ropes and sheaves, is critical to avoid wear-induced failures.
- Hydraulic seals and hoses require periodic replacement to prevent leaks affecting control responsiveness.
- Lubrication of swing bearings and joints extends component life and ensures smooth operation.
- Replacement parts must meet OEM standards for material and fit to maintain crane integrity.
- Boom: Primary arm of the crane used to lift loads.
- Hoist Drum: Cylindrical drum around which the wire rope is wound for lift hoisting.
- Outriggers: Extendable legs to stabilize the crane horizontally during lifting.
- Swing Bearing: The large bearing allowing the crane's upper part to rotate.
- Load Moment Indicator: Device monitoring load weight and boom position to prevent overturning.
- Sheaves: Pulleys around which hoist wire ropes run.
- Lagging: Gripping surface on drums, smooth or grooved, that aids rope traction.
