1.0 Safety
1.1 General Safety
1.1.1 Intended Function and Expected Use:
1.1.1.1. The KEITH®WALKING FLOOR®system is a reciprocating slat conveyor primarily
intended to load, hold, or unload bulk materials. It can also handle unit loads such as
pallets by using special handling techniques and possibly additional safety controls. The
system is supplied as a kit primarily intended for installation into mobile trailers or truck
bodies. The oor is often loaded through an open trailer top or through the rear doors.
The oor typically discharges material out the rear door. It is hydraulically actuated,
powered by a pump mounted either to a PTO or an electric motor. The basic system is
controlled by mechanically-actuated valves, but has the option for electrically-actuated
valves. The system is compatible with options and accessories to improve performance.
For example, it can be electrically controlled by hardwired switches or a wireless remote.
A CleenSweep®device can improve clean out. Floor slat styles are selected based on
the materials to be conveyed. The standard system handles a wide array of materials in
a non-hazardous, non-explosive environment. Special modications may be required for
special environments like food-grade applications or explosive conditions.
1.1.2 Improper Use
1.1.2.1. This equipment has been manufactured utilizing state-of-the-art technology in accordance
with acknowledged safety regulations. Nevertheless, dangerous situations could arise
from improper use, which could endanger life and limbs of personnel and cause severe
damage to the equipment and other assets. This equipment may only be used for its
intended purpose. It may only be operated in impeccable technical condition and in
accordance with the proper use and this user manual. Problems, which could a󰀨ect
safety, must be resolved immediately. The manufacturer is not liable for any damage
caused by improper use or arbitrary modications. The installation, commissioning,
operation, and maintenance instructions must be followed as outlined in this manual.
1.1.2.2. Personnel must not enter the danger zone(s) when the system is enabled. Specically,
nobody should be inside, under, or behind the trailer in the unloading zone during
operation. Additionally, no one should be in a full or lling trailer. Lock-out and tag-out
procedures must be followed before accessing the drive area.
1.1.2.3. The maximum load capacity must not be exceeded. (See 2.0 Specications section)
1.1.2.4. The hydraulic power source must not exceed the pressure and ow ratings. Install a relief
valve to ensure the maximum pressure is not exceeded.
1.1.2.5. Control circuitry must not be altered or bypassed.
1.1.2.6. Safeguards must not be altered or bypassed.
1.1.2.7. The oor structure must not be altered.
1.1.2.8. The oor should not be used to handle any material other than specied.
1.1.2.9. The user and system designer must understand the characteristics and safe handling
requirements of the material that is being conveyed.
1.1.2.10. Bulk materials are by nature unstable and owable. Avoid burial by avoiding contact with
the material.
1.1.3 Training
1.1.3.1. Operators must read and understand this manual before operating or maintaining the
machine. Only qualied, trained personnel may execute commissioning, operation, and
maintenance of the system.

2 DOC06387 Rev. C
OWNER / OPERATOR MANUAL KICD - Container DriveOWNER / OPERATOR MANUAL KICD - Container Drive
1.1.4 Personal Protective Equipment
1.1.4.1. Always wear protective equipment appropriate for risks associated with each phase of
the system’s life, including transportation, installation, assembly, operation, inspection,
maintenance, and dismantling, disabling, and scrapping. As a minimum, this includes the
following personal protective equipment:
• Safety glasses • Protective/traction shoes
• Gloves • Helmets
• Welding/grinding protection • Hearing Protection
• Thermal protection such as coats
1.1.5 Airborne Noise Emission
1.1.5.1. There is not a dened workstation; sound pressure levels emitted by the
WALKING
FLOOR
® modules were measured at a height of 1.6 meters from the oor surface and a
distance of 1 meter from the surface of the
WALKING FLOOR
®system at the drive area.
• The A-weighted emission sound pressure level = 74.8 dB
• The peak C-weighted instantaneous emission sound pressure level = below 130 dB
[63 Pa]
1.1.5.2. Slower oor speeds result in less noise.
1.1.6 Temperature
1.1.6.1. Operation of the system generates heat in the hydraulic oil. Hot oil can damage the
internal seals, resulting in a failure to operate.
1.1.6.2. Overheated oil can degrade rapidly. Hot oil and the resulting hot surfaces can cause
burns. Do not allow the oil temperature to exceed 140 °F [60 °C].
1.1.6.3. KEITH recommends some or all of the following temperature control measures depending
on the circumstances. High duty cycle systems and hot environments will require more
control measures.
• Maintain adequate oil level in the reservoir.
• Install a thermometer or sensor to monitor oil temperature.
• Install a cooler.
• Set a sensor to automatically shut down the system if oil temperature exceeds
140 °F [60 °C].
1.1.7 Lighting
1.1.7.1. Do not use or service the system in an environment of insu󰀩cient light.
1.1.8 Movement Around the System
1.1.8.1. Hydraulic oil can be slippery. Clean up oil spills immediately.
1.1.9 Hydraulic Oil Safety
1.1.9.1. See the Material Safety Data Sheet (MSDS) for the oil used in your system for further
information about hydraulic oil safety.

3 DOC06387 Rev. C
OWNER / OPERATOR MANUAL KICD - Container DriveOWNER / OPERATOR MANUAL KICD - Container Drive
1.1.9.2. In an accident involving high pressure equipment, hydraulic oil may be injected under
the skin. Such an accident may result in a small, sometimes bloodless, puncture wound.
However, due to the system’s driving force, material injected into a ngertip can be
deposited into the palm of the hand. Within 24 hours, there is usually a great deal of
swelling, discoloration, and intense throbbing pain. Immediate treatment at a surgical
emergency center is recommended.
1.1.9.3. Do not use high pressure systems in the vicinity of ames, sparks, and hot surfaces. Use
only in well ventilated areas.
1.1.9.4. Use only designated appropriate ll and drain ports for the oil.
1.2 Design / Installation Safety
1.2.1 Kit Components
1.2.1.1. The kit consists of a drive unit, ooring, and miscellaneous boxed parts. These modules
are intended to be anchored in a shipping frame or stacked at and braced with dunnage
for shipping and storage.
1.2.2 Installation
1.2.2.1. Use designated lifting points if provided on drive or shipping frame.
1.2.2.2. Only use equipment with appropriate capacity ratings to lift and handle components.
1.2.2.3. Use appropriate lifting procedures when handling loose or boxed components.
1.2.2.4. The oor must be installed far enough away from other equipment or xtures to prevent
the moving parts of the oor module from creating a crush or pinch hazard.
1.2.3 Danger Zones
1.2.3.1. The reciprocating action of the oor creates pinch and shear points by nature. Specically,
drive area cylinder, cross-drive, and slats approaching each other, frame components, or
walls. These and any other relevant exposed areas must be guarded.
1.2.3.2. The oor must be incorporated into surroundings such that movement of the material on
the oor does not create crushing, burial, drawing in, or entrapment hazards. The system
must be designed to limit access to the material ow path.
1.2.4 Electric Components and Installation
1.2.4.1. KEITH recommends connecting to earth ground (whenever possible).
1.2.4.2. Wiring must be connected consistent with local codes and regulations, including
electromagnetic interference regulations.
1.2.4.3. Adequate electric overcurrent protection must be provided.
1.2.5 Hydraulics
1.2.5.1. Hydraulic piping and components must be constructed of materials that are rated for
system pressures, and must be installed with best industry practices. Follow all pipe,
tubing, tting, and hose manufacturer installation and routing guidelines.
1.2.5.2. Hydraulic piping should be supported and isolated from vibration. Contact KEITH for
recommendations on installation.
1.2.5.3. Place protective shrouds around the hydraulic tubing in any areas that may have
operators or people frequently nearby.

4 DOC06387 Rev. C
OWNER / OPERATOR MANUAL KICD - Container DriveOWNER / OPERATOR MANUAL KICD - Container Drive
1.2.6 Controls
1.2.6.1. The control panel must be located such that it is easily accessible for all sizes and
capacities of people, and allows the operator to move freely (whenever applicable).
1.2.6.2. Control devices must be located outside of danger zones, such that any exposed persons
in danger zones are visible from the control station.
1.2.6.3. An acceptable means must be provided to monitor the status and movement of the load.
1.2.6.4. The oor can generate enormous horizontal force which can destroy improperly designed
surroundings. The oor module must not be allowed to compact material against an end
wall or door, or end walls and doors must be designed to absorb these forces.
1.2.6.5. Do not allow the oor to move material toward the front of the trailer when material is
contacting the front wall. KEITH recommends installing limit switches to prevent this.
In the absence of a sensor switch, the operator must be keenly aware of the load
position, and the control system must require the operator to hold the run signal in the on
position to continue running, such that releasing the run signal causes the oor to stop
(momentary signal).
1.2.6.6. Material compacted against closed doors can force the doors open dangerously fast when
the door latch is released. The impact can cause serious injury or death. Do not allow
the oor to run when the doors are closed. Do not open a door when it is possible that
material may be compacted against it. KEITH strongly recommends installing a control
interlock switch to prevent the oor from running when the door is closed. KEITH also
recommends a door latch that can be remotely actuated by someone away from the door
area unload zone.

The rst group of slats (approximately every 3rd slat)
moves under the load.
Load does not move.
Stage 2
The second group of slats moves under the load.
Load does not move.
Stage 3
The nal group of slats moves under the load.
Load does not move.
Stage 4
All slats move together.
Load moves with the oor toward the discharge end.
(Stages 1, 2 & 3 require more pressure than Stage 4)

Stage 2
Stage 1
Pressure in the rear of all cylinders.
Control valve actuator sends pressure to close the control valve
and open the restrictor valve in the front manifold. Cylinder #1
is open to return, causing it to move. (Load does not move.)
Blocked by check valves.
Note: Stage 1 requires more pressure than stage 4.
Pressure still in rear of all cylinders.
Cylinder #1 completes its full stroke, opening the check valve,
allowing the oil in cylinder #2 to escape, causing it to move.
(Load does not move.)
Blocked by check valve.
Note: Stage 2 requires more pressure than stage 1.
Stage 3
Pressure still in rear of all cylinders.
Cylinder #2 completes its full stroke, opening the check valve,
allowing the oil in cylinder #3 to escape to return, causing it to
move. (Load does not move.)
Note: Stage 3 requires more pressure than stage 2.
Stage 4
Cylinder #3 completes its stroke, shifting the switching valve, which
reverses pressure and return, transferring the pressure to the front of
all cylinders.
All cylinders are now open to return and move to the rear of the
trailer together, moving the load.
As the cylinders complete their stroke, cylinder #1 shifts the
switching valve, which reverses pressure and return, transferring the
pressure to the rear of all cylinders again and the cycle starts over.
Note: Stage 4 requires less pressure than stages 1, 2, or 3.
