Why “Just One Brake” Is Unsafe Practice

Posted on 10 February 2026

Introduction

During a recent NHS training session on patient hoisting, a physiotherapist suggested that it was acceptable to apply one brake on a mobile hoist to help turn it – particularly on thick carpet where manoeuvring can feel difficult.

This advice was well-intentioned, but it is incorrect and unsafe.

After checking manufacturer guidance, best-practice manuals, and current manual-handling principles, it’s clear that applying a single brake to aid turning should not be taught or used in clinical practice.

Let’s unpack why.

Why the “One Brake to Turn” Idea Exists

This practice often comes from:

  • Frustration with thick or soft flooring
  • Older habits passed down informally
  • A belief that locking one wheel creates a “pivot point”
  • Pressure to “just get the job done” safely and quickly

While understandable, difficulty does not justify unsafe technique.

What Manufacturers and Guidance Actually Say

Across major hoist manufacturers (e.g. Arjo, Invacare, Oxford/Joerns), guidance is consistent:

Castor brakes are designed for:

  • Parking the hoist
  • Storage
  • Transfers when the hoist is stationary

They are NOT designed to be used while manoeuvring a hoist with a patient suspended.

No manufacturer recommends:

  • Locking one castor to steer
  • Creating a pivot during movement
  • Dragging or twisting a braked hoist

The Real Risks of Using One Brake

1. Increased Risk of Tipping

Locking one castor introduces torsional forces through the hoist frame. With a patient suspended, the centre of gravity is already elevated – adding resistance on one wheel increases instability.

2. Sudden Release = Loss of Control

If the brake slips or releases unexpectedly:

  • The hoist can lurch
  • The patient may swing
  • The handler may lose balance

3. Higher Manual Handling Risk for Staff

Forcing a hoist against a locked wheel:

  • Increases push/pull force
  • Raises shoulder, wrist, and lower-back strain
  • Encourages twisting – one of the highest-risk movements

4. False Sense of “Control”

It can feel more controlled – but that control is artificial and unpredictable, especially on carpet.

What Should Be Done Instead?

All Brakes Off When Manoeuvring

When moving a hoist with a patient:

  • All castor brakes should be released
  • The hoist must roll freely

This allows:

  • Even load distribution
  • Predictable movement
  • Reduced force through the frame and handler

Re-Position Before Lifting

If turning space is limited:

  • Adjust the hoist’s position before lifting
  • Align the legs and direction of travel early
  • Avoid mid-lift corrections where possible

Use Micro-Movements

Instead of trying to pivot:

  • Use small forward/backward rolling movements
  • Gently guide the hoist into alignment
  • Lower slightly if safe to improve control

Address the Environment

If thick carpet is the issue, the solution is not technique-workarounds:

  • Review flooring suitability
  • Consider glide sheets, track hoists, or alternative equipment
  • Escalate via risk assessment rather than improvisation

What This Means for Training and Teaching

This scenario highlights a key issue in manual handling education:

Clinical seniority does not override equipment guidance or biomechanics.

Even experienced clinicians can unintentionally pass on unsafe shortcuts if they’ve never been formally challenged.

As trainers, we have a responsibility to:

  • Teach manufacturer-aligned practice
  • Challenge myths respectfully
  • Model evidence-based decision-making

The Bottom Line

Putting one brake on a hoist to help turn it is not safe practice.

It:

  • Increases tipping risk
  • Raises manual handling injury risk
  • Is unsupported by manufacturer guidance
  • Should not be taught or used in healthcare settings

If a hoist is difficult to move, that’s a risk-assessment and equipment issue, not a technique problem.
