Excavator Lift Plans: A Complete Guide for UK Contractors

Excavators are primarily designed for digging, but they're frequently used for lifting operations on UK construction sites. While this versatility makes them invaluable, it also creates legal obligations under LOLER 1998.

When Do You Need a Lift Plan for Excavator Operations?

Under LOLER 1998, any lifting operation must be properly planned by a competent person. For excavators, this means you need a formal lift plan whenever the machine is used to lift and move loads rather than just digging.

The key distinction is simple: if the excavator bucket is replaced with lifting equipment (chains, slings, shackles) or if you're using the bucket itself to lift rather than dig, you're conducting a lifting operation that requires planning under LOLER.

Common Excavator Lifting Operations

• Drainage and utilities work - Lifting concrete pipes, manholes, and precast chambers
• Groundworks - Moving precast pads, kerb stones, and road gullies
• General construction - Lifting materials to elevated areas and positioning steelwork
• Demolition support - Controlled lifting of materials and equipment

Legal Requirements for Excavator Lifting

LOLER Regulation 8 requires that every lifting operation must be properly planned by a competent person, appropriately supervised, and carried out safely. For excavator lifting, this typically means engaging a CPCS Appointed Person.

What Must an Excavator Lift Plan Include?

A compliant excavator lift plan documents the safe system of work including:

• Excavator details and lifting capacity at various radii
• Specification of lifting accessories (chains, slings, shackles)
• Load description, weight, and centre of gravity
• Ground bearing capacity assessment
• Identification of overhead hazards and underground services
• Step-by-step lifting sequence
• Risk assessment and control measures

Understanding Excavator Lifting Capacity

Unlike mobile cranes with published lifting capacities, excavators have limited manufacturer guidance for lifting operations. Safe lifting capacity is typically 50-75% of the maximum theoretical capacity to account for dynamic effects, ground conditions, and wear.

Ground Conditions for Excavator Lifting

Ground bearing capacity is critical for safe operations. An excavator under load applies significantly more pressure to the ground than during normal digging. The Appointed Person must assess soil type, proximity to excavations, and requirements for ground mats.

Supervision and Communication

Most excavator lifting operations require a trained slinger signaller who attaches the load, directs the operation using standard hand signals, and supervises safe execution.

When to Engage an Appointed Person

While simple excavator lifting operations might be planned by experienced site staff, engaging a CPCS Appointed Person provides legal compliance assurance, technical expertise, risk management, and professional documentation suitable for HSE inspection.
