Upright POWERED ACCESS TL34, Service Manual

Page: 8 / 79

The
TL34
is a trailer mounted work platform with a 2-man cage giving access to maximum
height of 12.20m. It offers safe, versatile and easy access for two men plus tools up to a
total of 215Kg. Its unique boom configuration allows this height to be reached while still
offering compact closed dimensions and exceptional manoeuvrability. It is manufactured
from steel hollow sections conforming to BS4360 1986. All joints are fully welded by
Metal Inert Gas (MIG) or Manual Metal Arc (MMA) processes. The main pivots are set in
bushed housings. The bushes are self-lubricating for minimum maintenance and long
life. The main boom pins are chromed and all other pins are Tuftridge
TH
coated.
The platform is powered by a 12V DC battery pack operating an electric motor which
in turn drives a hydraulic pump. This provides a maximum hydraulic pressure output
of 210 Bar max. Battery powered models are fitted with an ‘on-board’ battery charger.
Limit switches are fitted to the stabilisers thereby ensuring that the booms cannot be
elevated unless the stabilisers are first deployed. Machines equipped with hydraulic
stabilisers are also fitted with a limit switch on the booms to ensure that the stabilisers
cannot be operated when the booms are elevated. Lift is provided by single acting
hydraulic cylinders on the top and bottom boom and rotation is achieved by the use of a
hydraulic motor driving a pinion via a gearbox.
Control is provided by a live hydraulic system. Lift is controlled from monoblock bank
valves, mounted in the cage and in the control cabinet at the ground, which allows
precise control of the two platform functions (Lift and Rotate). The lift cylinders are fitted
with solenoid operated check valves which ensure that in the event of hose failure, the
platform will not descent without deliberate action being taken to lower the platform. The
lift cylinders are also fitted with a flow control valve to control the rate at which the
platform descends.
All equipment at ground level except the rotation motor is situated on the cabinet on the
side of the platform.
Facility is provided for lowering the platform at ground level in the case of any emergency
