Introduction

The Thomson Engineering Design LBB20-02 Long Bearer Beam is designed for handling individual sleepers and bearers in the construction of switch and crossing panels.

The device is primarily designed for fi tment to an excavator but, using the THA20 adapter, may also be fi tted to telehandlers.

Bearers up to 4,850 mm long and weighing up to 750 kg are delicately handled and precisely placed using this precision attachment which features soft urethane gripper pads and a host of other features all designed to ensure that the bearers are handled swiftly and safely.

A load-levelling feature is built into the hydraulic system which allows the operator to pick up a bearer then shift it along the length of the beam so that unbalanced bearers can still be carried perfectly level. The load levelling feature engages automatically when a bearer is lifted and uses the same control as is used to grip and release the bearer.

A second automatic system disconnects the grab control once the bearer is lifted preventing release of the load until it is lowered onto the ground or a fi rm support.

The frame of the device is a fully welded steel construction painted yellow as standard (other colours to order).

The LBB20-02 Long Bearer Beam is one of a range of sleeper handling devices from Thomson Engineering Design. Please enquire or see our website for details of the full range.

Key Features

Carries all BearersLong stroke hydraulic cylinders allow for a wide range of bearer lengths to be handled by a single device.

Fully controlled from the cab of the host machine the LBB20-02 can safely handle bearers from 2,050 mm to 4,300 mm long.

Adjustable for all TypesBearers of different depths can be accommodated by a simple adjustment of the landing pad position at each end of the beam.

Delicate, Precise HandlingWhen the LBB20-02 is placed on the bearer its weight is supported by a hard delrin pad which protects the top surface of the bearer as the jaws slide to grip the load.

The grip force is transmitted into the bearer using soft urethane pads which, as well as being highly durable, improve the friction grip and help to secure the load.



Load LevellingOnce the beam is carrying a bearer it can be shifted along the beam length to achieve perfect balance of the beam and load.

Load DetectionSprings on the rotator mount check the weight of the beam and when it is laden with a bearer actuate valves to prevent release of the load and transfer control to the load levelling system.

Hose Burst ProtectionFailure of a hose on the device or failure of the hydraulic system on the host machine will cause the cylinder mounted check valves to automatically lock the cylinders in place securing the load.
