Operator Compartment Safety & Interlocks
When an operator contacts the Entry Bar safety switch during travel on a Crown RC 5700 stand-up forklift, the alarm sounds and the truck slows to a stop. Here is what the official operator manual specifies and how to handle unexplained activation.

Stand-up counterbalance forklifts require the operator to remain completely within the operator compartment to prevent crush injuries. On the Crown RC 5700 Series, the Entry Bar® safety switch guards the rear compartment entrance. If an operator places a foot on this switch while traveling, the truck sounds an audible alarm and initiates a controlled slow-to-stop response. Understanding this safety interlock helps distinguish normal operator-stance events from conditions requiring supervisor notification and removal from service under OSHA regulations.
On the Crown RC 5700, the Entry Bar safety switch is positioned across the rear entrance of the operator compartment. Per page 16 of the operator manual, if an operator places a foot on the entry bar while traveling, the alarm will sound and the truck will slow to a stop. Operators must keep both feet entirely within the operator area and clear of the entry bar during travel.
Confirm that the operator maintains the proper side-stance position within the compartment boundaries, with the left foot positioned on the brake pedal (stepping down to release the service brake) and the right foot on the sensor pad. Feet must remain clear of the entry bar and the posture relief step during active travel.
Per the Crown operator manual, do not use the truck if it is not working correctly. If the entry bar alarm sounds or the truck slows to a stop without physical foot contact on the entry bar, do not continue operating or attempt deliberate event reproduction.
In accordance with Crown instructions and OSHA 29 CFR 1910.178(p)(1), immediately take the truck out of service, notify your supervisor, and document the observed behavior (truck model, serial number, hour meter reading, and operating conditions) for authorized service personnel.
| Operating Scenario / Observation | Source-Defined Machine Response | Mandatory Operator Action |
|---|---|---|
| Foot contacts Entry Bar while traveling | Alarm sounds and truck slows to a stop | Keep feet in operator area and clear of entry bar during travel (Manual p. 16) |
| Alarm or slow-stop occurs without entry bar contact | Truck exhibits unexpected alarm or deceleration | Do not use truck; notify supervisor immediately (Manual p. 16) |
| Heel or foot removed from Left Brake Pedal during travel | Service brakes apply to stop truck in shortest distance | Maintain foot on brake pedal to keep service brake off (Manual p. 20) |
| Right foot off Sensor Pad during startup/operation | Truck is not ready for operation | Place right foot on sensor pad per pedal instructions (Manual p. 16) |
| Persistent or unexplained safety switch activation | Truck not in safe operating condition | Remove from service and tag out until repaired by authorized personnel (OSHA 1910.178(p)(1), (q)(1)) |
The Crown RC 5700 Series stand-up counterbalance lift truck incorporates an Entry Bar® safety switch along the operator compartment entrance. Stand-up rider trucks require the operator to remain completely within the operator compartment profile during travel to protect against pinch and crush hazards from fixed objects or passing warehouse structures.
The operator manual explicitly defines the function of this switch: keeping feet inside the operator area and clear of the entry bar is required during operation. When an operator places a foot on the entry bar while the truck is moving, the control system sounds an audible alarm and slows the truck to a controlled stop.
Safe operation of the Crown RC 5700 requires correct foot placement on the operator floorboard. As stated in the operator manual, normal operation requires placing the left foot on the left brake pedal and the right foot on the sensor pad. The truck is equipped with a posture relief step, but the manual specifies that an operator may rest a foot on this step only when the truck is not in operation.
Operators must avoid resting heels or footwear on the entry bar threshold during motion. When an alarm or slow-stop event occurs because an operator shifted stance onto the bar, restoring proper foot position inside the compartment and keeping clear of the bar aligns with manual guidelines.
When an Entry Bar alarm sounds or a slow stop occurs in the absence of foot contact, the truck is not working correctly. The Crown manual gives a clear instruction: 'Don't use the truck if it's not working correctly. Notify your supervisor.' Facility staff and operators must never bypass, wedge, shim, or open the entry bar assembly.
Under federal regulation OSHA 29 CFR 1910.178(p)(1), any powered industrial truck found to be defective or unsafe must be immediately taken out of service until restored to safe operating condition. Section 1910.178(q)(1) mandates that all repairs be performed exclusively by authorized personnel. Submitting a clear dispatch record with the truck model, serial number, hour meter reading, and detailed observation allows qualified service technicians to conduct proper diagnostic procedures.
This editorial guide applies specifically to Crown RC 5700 Series stand-up electric counterbalance forklifts. It details the source-documented behavior of the Entry Bar safety switch and operator floorboard controls per Crown Operator Manual 600092-200A and OSHA 29 CFR 1910.178. It does not provide component-level diagnostic procedures, electrical fault schemas, or internal mechanical repairs, which must be performed by authorized service personnel.
