The LP350 Low Profile Skidding System is designed to work with most 10,000 psi (700 bar) hydraulic
power units; however, it is recommended to be used with Hydra-Slide’s synchronous HYDRA-PAC
power units. The system comes with a steel storage box to store all system components and necessary
hardware to assemble and operate.
1.3.1 The Workstation
The LP350 Low Profile Skidding System is remotely operated. It is suggested that the operator set up
his/her workstation in a safe location, clear of the load to be skidded, and with as much visibility of the
load and skidding system as possible.
1.3.2 Intended Use
The LP350 Low Profile Skidding System is used to move heavy equipment up to 350 tons (318 tonne)
safely and in a controlled manner.
1.4 Safety Precautions
Set up and operate the LP350 Low Profile Skidding System only under the direction and supervision
of experienced and qualified personnel.
This section contains information required for the safe operation of the LP350 Low Profile Skidding
System. Please read and understand the instructions and safety warnings that come with the equipment.
Failure to comply with these safe operating recommendations could result in property damage or
personal injury. Always follow safe work practices.
The LP350 has been designed and manufactured for a maximum load capacity of 350 tons (318 tonne).
The maximum operating pressure of the push cylinders is 10,000 psi (700 bar). Do not exceed these
values at any time when using the system.
Use in any other manner or for any other purpose is not intended and is not recommended by the
manufacturer. The operational safety of the system is only assured if used as intended.
1.4.1 General Safety Precautions and Potential Misuse
 Only qualified operators should install, operate, adjust, maintain, clean, repair or transport this
equipment.
 Only use this equipment in accordance with its intended use and follow all instructions.
 Never exceed recommended maximum pressure and stroke ratings. Good practice recommends
using only 80% of these ratings.
 Always wear appropriate Personal Protective Equipment.
 Protect all equipment from potential hazards such as fire, explosion, sharp surfaces, extreme
heat/cold, corrosives, and heavy impact.
 Anticipate possible problems and take steps to avoid them. If in doubt, ask.
 Never operate any equipment without all provided guards and safety devices in place and in good
working condition.
 Lift and move slowly and check often. Control the load at all times.

3
 Double-check track connections before loading the track.
 Avoid standing in the line of force of hoses or any hydraulic components.
 Lift or move equipment and components using only the provided lift lugs or handles, etc. and
only employ proper lifting equipment and techniques. Never lift by the hoses or hydraulic
fittings.
 Never place any part of your body under the load unless the load is on a solid support.
 Never place any part of your body between a moving load and a solid obstacle where there is
danger of crushing.
 Take steps to keep all equipment clean and free from possible damage. This is particularly
important for hoses and couplers.
 Don’t allow hoses to kink, twist, crush, cut or bend tightly. Bending radius should be at least 4½
inches. Inspect hoses and couplers before each use and remove from service if any signs of
damage are noted. Never attempt to repair a hose.
 Never handle hoses or couplers while they are under pressure, even when wearing Personal
Protective Equipment. There is risk of serious personal injury from hose leaks, faulty or
improperly connected couplers.
 Use safe practices to bleed a pressurized hose or coupler; use only a specially-designed coupler
bleed tool such as a CT-604 Safety Tool available through Hydra-Slide Ltd.
 Always ensure that jacks and cylinders are used parallel and in line with their axis. Never use a
jack or cylinder at an angle or to “kick” or move a load sideways. Use only Hydra-Slide’s AS500
Alignment Shoes for these types of operations.
 Do not apply any external forces to the load or track other than those from proper use of the
supplied hydraulic cylinder(s), i.e. do not use come-alongs, winches, etc. to push or pull the load
 If jacking a load, always use appropriate blocking or cribbing to guard against a falling or out of
control load.
 Do not use any lubricants on the system other than those provided and/or specified for use.
1.4.2 Operator Training
The operator should be experienced in the safe operation of high pressure hydraulic jacking systems.
The operator should also read and understand these Instructions in full prior to operating the system.
1.4.3 Residual Risks and Protective Measures
Observing the safety precautions indicated in these Instructions minimizes the risks associated with
using the LP350 Low Profile Skidding System, however residual risks remain in the event of loss of
control of the load while skidding. It is recommended to always use the provided stop blocks as
described in Section 3.3.

4
1.4.4 In Case of Breakdown
In case of equipment breakdown or other operational problems, cease operation immediately and take
any necessary steps to secure equipment and protect surroundings and personnel. Depressurize hoses
and all hydraulic components (use coupler bleed tool as required). Identify the problem. Jack up the
load to remove weight from skid system and secure it with blocking or other support. Correct the
problem and/or replace any broken or defective components. Jack down load onto skid system and
continue operations in accordance with these Instructions.
1.4.5. Airborne Noise Emissions
Operation of the LP350 Low Profile Skidding System does not produce airborne noise exceeding 70
dB(A).
1.4.6 Non-Ionizing Radiation
Operation of the LP350 Low Profile Skidding System does not produce non-ionizing radiation.

2 - ASSEMBLY AND SETUP
Before each use, inspect the system for any signs of damage or oil leaks. If any issues are found, do not
operate the LP350 until corrective measures have been taken.
2.1 General Instructions
 Establish a clear path for the load to be moved.
 Raise load (using other means) to a sufficient height to place skid system under.
 Place track under load.
 The track sections are bi-directional and symmetric; any two ends may be connected together.
 Connect the track plate sections using the connector plates supplied and secure with the
countersunk screws. Hand tighten only and ensure that the Tracks are set up parallel and level.
It may be advantageous to have a slight incline in the direction of travel but never set up or
operate the system on a decline without an adequate external holdback.
 Tracks must be oriented so the load will move in a straight line to the desired location.
 Tracks must be positioned such that the ratchet slots are equidistant from the edge of the load so
the push cylinders will be able to extend in synchronization.
 The track must be fully supported over its entire length. Excess deflection can cause severe
damage.
2.2 Track Plate Connection
The wedge design of the track connection requires that the ends of the track sections be in direct contact
so the feet of the connector plate can fit into the slots on the two adjacent track plate sections (see detail
figure below).
 Set up two track sections end-to-end with track ends in full contact.
 Place track connector plate over the two adjacent tracks ensuring bottom of connector plate is
sitting flat on the top face of the two track sections.
 Once the connector plate is in place, pull the tracks apart so the inside faces of the feet on the
connector plate come into direct contact with the tracks.
 Secure the track connector plate to the track sections using the supplied bolts (see figures below).

2.3 Slider Plate Assembly
Insert the skid shoe slider plates on the track under the load and connect the holes over the pins. Ensure
that the guide bars engage and that the slider plates move freely on the track.
The LP350 system has three different types of slider plates. This allows the system to be set up and
operated in several different configurations, depending on the size of the load being moved. The three
slider plate types are shown below.
The slider plates are connected to each other using male-female type connections (see above figures).
For moving longer, single-piece loads it is possible to divide the slider plates into front and rear sections.

7
For this configuration, it is necessary to ensure that the front and rear slider plates do not lose contact
with the load as they may become displaced; it is recommended to purchase additional pusher heads for
the rear end in order to maintain direct contact with the load.
When setting up and connecting the slider plates, ensure that the two slots on the ends of the male and
female slider plates are on the outsides of the slider plate assemblies so that the pusher heads can be
connected (see details in Section 2.4).
2.4 Slider Plate – Pusher Head Connection
 Attach the pusher heads to one end of each slider plate assembly and engage the hinged locking
pins.
 Ensure that the area on the bottom of the load where it will contact the slider plate assembly is
clear and is a suitable supporting surface.
 Position the slider plate assembly under the load and ensure that the weight of the load will be
distributed evenly over the surface of the slider plates. Note:
o Do not exceed 30,000 lbs per foot of slider plate length used (44,000 kg per meter
of length)
o Do not point-load
o It is good practice to use a friction material such as wood or rubber between the
skid shoe and the load
 The pusher heads must make direct contact with the load, otherwise the slider plates can bend
causing severe damage to the system.
